Foreword
Pesticide poisoning in the United States remains under-recognized and under-treated. The lack of
attention to pesticide poisoning exists in spite of the ubiquity of pesticides in our homes, work-
places, and communities, and despite the considerable potential for pesticide-related illness and
injury. Communities expect that their primary care providers will be prepared to deal with
pesticide-related health conditions, as well as other environmental illnesses, but often times they
are not.

This document is part of a national initiative aimed at changing the current situation. The National
Strategies for Health Care Providers: Pesticides Initiative has set forth a strategic direction for the
nation to improve the recognition, management, and prevention of pesticide-related health
conditions.The vision is for all primary health care providers to:

•  Possess a basic understanding of the health effects associated with pesticide exposures as
    well as broader environmental exposures.

•  Take action to ameliorate such effects through clinical and prevention activities.

Achieving this vision means incorporating some changes in educational institutions related to                           ฐ
the health professions - medical schools, nursing schools, residency, and practicum programs -
to equip students better to deal with pesticide-related exposures and health conditions.

These guidelines outline the knowledge and skills that students in the health professions need to
have about pesticides. We recognize the challenge that health educational institutions face in
terms of incorporating additional content. Nevertheless, it is important to find room for pesticide
concerns - both in terms of the very real health threats that they pose, and as a first step in
addressing the growing problem of environmental toxins. Medical and nursing schools - and
individual faculty members - will of course wish to make their own choices about how and where
to incorporate this information in their courses. We hope these guidelines help in that task.

These guidelines form one of two documents that outline the competencies and skills that health
care professionals should have in the pesticides/environmental health area. This document focus-
es on the knowledge base that should be mastered by students as part of medical or nursing
training. The companion document defines the skills and knowledge base that should be mas-
tered and demonstrated by primary care physicians and nurses in the practice arena. The authors
of both documents collaborated to ensure consistency across both documents.

The two documents were developed specifically for everyday, frontline health care professionals,
rather than for specialists and researchers. The Educational Competency guidelines are aimed at
basic and advanced components of educational  institutions, rather than specialties such as occu-
pational and environmental medicine. Similarly, the Practice Skills guidelines are aimed at primary
care providers, rather than medical toxicologists  or specialists in occupational or environmental
medicine.

As faculty and administrators in medical and nursing  schools decide how to incorporate pesticide-
related information, it is hoped that these national guidelines and the larger initiative on pesti-
cides and health care providers will serve as a model  for integrating other environmental health
issues into health care provider education and training.
                       Background  on Pesticides and Health Care Providers

                       The need for improvements in environmental health training has been expressed by a number of
                       health professional groups, academic institutions, as well as government and community organiza-
                       tions. In 1994, the American Medical Association adopted a resolution urging Congress, govern-
                       ment agencies, and private organizations to support improved strategies for the assessment and
                       prevention of pesticide risks.These strategies included systems for reporting pesticide usage and
                       illness, as well as educational programs about pesticide risks and benefits.

                       In a number of studies published in the 1990s, the Institute of Medicine expressed its concern that
                       health care providers are not prepared to manage this problem, focusing on the issue of environ-
                       mental health education and the roles of nurses and physicians (IOM 1988, IOM 1991, IOM 1993,
                       Pope et al, 1995). Each report outlined the deficits in current educational curricula for environmen-
                       tal medicine, and recommended improvements. At a minimum, primary care physicians and nurses
                       should be able to identify possible occupationally or environmentally induced conditions and make
                       appropriate referrals (IOM 1988).The 1993 report offered additional recommendations: eliciting a
                       detailed environmental history, recognizing signs and symptoms, understanding the relevant toxi-
                       cology and exposure factors, identifying the available resources for assistance, and understanding
                       legal and ethical responsibilities.

The National Strategies for Health Care Providers: Pesticides Initiative (http://www.neetf.org/Health/
providers/index.shtm) began in 1998 and is a partnership of the U.S. Environmental Protection
Agency (EPA) and The National Environmental Education & Training Foundation (NEETF),in collab-
oration with the U.S. Department of Health and Human Services (DHHS), the U.S. Department of
Agriculture (USDA), and the U.S. Department of Labor (DOL).

From the outset, this national interagency initiative has been conceived of as a long-term effort.
Working with an expert panel and multiple workgroups, the initiative sought a broad-scale
involvement of stakeholders, including federal agencies, academic institutions, professional organi-
zations, foundations, farmworker and farm groups, industry and trade associations.  As part of this
initiative, EPA issued a substantially revised edition of Recognition and Management of Pesticide
Poisonings (Reigart and Roberts, 1999), a landmark handbook used by health care professionals
around the world. In 2002, the Implementation Plan: National Strategies for Health Care Providers:
Pesticides Initiative was published (NEETF, 2002). It outlines a set of strategies to move the initiative
forward in education, practice, and resource development.


Role  of Health Care Providers

Primary care providers are on the frontlines of health care. Patients and communities often look to
their primary care providers as important sources of information and guidance on suspected pesti-
cide-related health conditions. Primary care providers can play a key role in identifying and amelio-                        c
rating potential pesticide poisonings and exposure - but only if they are prepared for this role and                        ฐ
know where to turn for assistance. Providers must be able to problem solve with patients who
think an exposure has occurred. With the potential effects of pesticide exposure on health so
widespread  and consequential, an understanding of the pathophysiology and management of
pesticide exposure and toxicity is important in all areas of health care practice (general and
advanced/specialty), including assessment, diagnosis, planning intervention/treatment, and evalu-
ation (IOM 1993, Pope et al, 1995).

Prevention, health maintenance, and illness and injury management are included in the manage-
ment of pesticide exposure. Essential skills include a basic understanding of the health hazards of
pesticides, prevention and abatement methods, recognition, diagnosis, and treatment of pesticide
exposure, and utilization of resources for referral and assistance at both a patient and community-
based level. In addition to direct patient interventions, health care providers may assume the role
of educator, advocate, and policy planner on behalf of an individual patient or population of
patients.

When pesticide toxicity is discussed, most people usually think of an acute pesticide poisoning
incident in an agricultural setting. However, pesticide exposure regularly occurs in settings outside
agriculture as well, including urban environments, homes, and schools. Pesticides are also of con-
cern because of potential chronic health effects from long-term exposures. This is particularly
important for children, given their developmental risks for pesticide exposure and due to pesticide
residues on food.

Health  care providers must be aware of the potential effects of pesticide exposure on high-risk
groups such as infants, children, the elderly, and those with compromised immune systems. The
      Extensive resources on pesticides can be found at www.neetf.org/Health/Resources/healthcare.htm

-------
                        issue of children's susceptibility prompted Congress to enact the Food Quality Protection Act of
                        1996, the highlights of which are discussed in Competency 1-3 of this document. Epidemiological
                        studies tend to focus on worker exposure. Since the majority of the pesticide applicator work
                        force is overwhelmingly male, studies of women exposed to pesticides at work are few. In the
                        absence of good data, pregnant women should take extra care to avoid exposure to pesticides.

                        A comprehensive approach to nursing and medical practice requires awareness, recognition, and
                        treatment of critical factors that affect individual and community health, even if these factors are
                        not obvious at first to patients or providers.This initiative recognizes the unique role and functions
                        served by registered nurses and advanced practice nurses. In urban, suburban, and rural settings,
                        nurses are often the initial, and sometimes only, points of contact for people seeking health care. In
                        the context of a busy medical practice, physicians often rely on nurses to provide more in-depth
                        patient education  on many preventive issues, and pesticide-related exposures may be included
                        among these. Community or home health nurses also may visit patients in their homes, work-
                        places, and local communities, thus gaining firsthand knowledge of potential pesticide exposures
                        in these settings (Pope et al, 1995). Where possible, the physician should maintain community
                        contacts as well, as is the case with those with particular expertise  in environmental health and
                        occupational medicine.The opportunity for close interactions when health care providers are
                        "onsite" provides a better chance of detecting previously unrecognized health problems related to
                        pesticide exposure.

                        Finally, health  care providers have a role to play in minimizing the unnecessary use of pesticides.
                        Integrated Pest Management (IPM) is a sustainable approach aimed at providing effective control
ฐ-                       of pest populations while  minimizing economic, health, and environmental risks. Rather than rely-
                        ing solely on pesticide applications, IPM employs other tactics as well, including biological control
                        controls (parasites and predators); cultural controls such as mulching to prevent weeds, varying
                        planting dates to avoid susceptible windows for pest infestation, etc; and physical controls such as
                        installation of screens, improved sanitation practices, etc. Based on the identification of pests, mon-
                        itoring of pest populations, assessment of damage levels, and knowledge of available pest man-
                        agement strategies, an IPM specialist can provide intelligent advice. Many successful IPM pro-
                        grams have reduced energy inputs and pesticide use. Health care  providers should encourage
                        patients and communities to contact their local Cooperative Extension offices (see the county list-
                        ings of the local telephone book) for advice on IPM programs and  strategies suitable for their
                        homes, yards,  schools, and communities.


                        Incorporation into the  Curriculum

                        Although some progress has been made in introducing environmental health issues into the cur-
                        riculum of medical and nursing schools, more remains to be done. And yet, it is hard to find  space
                        in the already crowded curricula of medical and nursing schools for new topics and subject areas.
                        To facilitate integration, this  document notes possible "Points of Insertion" for each competency.
                        We strongly recommend that pesticide content be integrated into existing adult health, pediatric,
                        research, ethical/legal units of  instruction and community health nursing courses, both didactic
                        and clinical. This can be done,for example, by using pesticides to enhance existing case studies, or
                        as exemplars.

-------
The changing worlds of medical and nursing education present a challenge in identifying where in
the curriculum a particular pesticide topic would be most appropriate. Curricula are highly variable
in the form and substance of topics. Some schools of nursing and particularly some schools of
medicine have adopted Problem Based Learning or other case-based methods or organ system
approaches to all or most of their curricula. Many schools continue to use a traditional curriculum
and maintain a traditional governance structure based on departmental control of curriculum
structure. A topic such as pesticides may be adapted by faculties with either style of curriculum,
but the vehicle used may require modification of the teaching method and style.

In suggesting points of insertion into the curriculum, we have included such components as envi-
ronmental or preventive medicine electives, public sector medicine courses, etc. These serve only as
examples; many schools will have other courses or departments that the material could fit into
equally well. Schools that do not have such courses in place are certainly encouraged to consider
adding them.

The competencies proposed in this document recommend  integration of content into medical
and nursing curricula at all levels.  Competency I, Knowledge and Concepts of Pesticides, is consid-
ered the most important and basic level that should be incorporated into all curricula as a top pri-
ority. Content items marked with an asterisk (*)  are considered appropriate for the more
advanced health care student (i.e., residents or nurse practitioner students), in addition to the
other content items.

The role of faculty development in advancing a pesticide-related curriculum cannot be over-
emphasized. If one or more faculty members are identified  as having a special interest or ability in
Environmental Health/Toxicology, those members may serve as a resource for other faculty mem-
bers, especially when the small group clinical case scenario  method is used.

The next section of this document contains a brief "primer" on pesticides, with background materi-
al on pesticide regulation, uses, exposures, and absorption. The remainder of the document out-

A  Pesticide  Primer
A pesticide is defined as any substance that is used to kill or otherwise control a pest.The term "pesti-
cide" includes insecticides, herbicides, fumigants, fungicides, repellents, rodenticides, and disinfectants.
About 940 million pounds of pesticidal active ingredients are applied yearly to agricultural land to
control insects, weeds,fungi, nematodes, bacteria, and other crop pests (Aspelin and Grube, 1999). This
figure accounts for about three-quarters of the total used, with the remainder split about evenly
between applications by homeowners and professional pest control applicators (Aspelin and Grube,
1999). However, it should be noted that on a per-acre basis, homeowners use many times more pesti-
cide on their lawns and gardens than the amounts applied on agricultural land (Robinson et al, 1994).

Pesticides in use in the U.S. today differ in significant ways from the pesticides relied on from the
1940's through the 1970's. DDT and several other organochlorine insecticides have long since
been banned from use in this country. Although these older products tended to have low acute
toxicity to humans, they had very long half-lives. Their persistence in the environment, coupled
with their tendency to be stored in fat, allowed them to accumulate in living organisms and to bio-
concentrate in the food chain.
By contrast, the newer pesticides tend to have shorter half-lives and to be water-soluble, so that
they are excreted (primarily in urine) and are less persistent in the environment. However, the acute
toxicity of some of the newer products (notably organophosphate and carbamate insecticides) is
much higher than the older products, making them more hazardous for users to handle. In addi-
tion, their increased water solubility raises the likelihood of contamination of ground water as a
result of improper application, poor well construction, improper disposal, or leaching. Whereas earli-
er pesticides were aimed at controlling a broad spectrum of pests, many  pesticides today are far
more specific in their action. Also, today's pesticides are effective at much smaller concentrations
than in the past. Together, the latter two factors mean that a larger variety of different products are
in use, but in a far smaller volume (ounces per acre, rather than pounds per acre) than in the past.
Nevertheless, overall pesticide use (Ibs/yr) has steadily increased over the years.                                         11
By volume, herbicides account for the majority of applications to agricultural crops. Other uses of
pesticides include applications to:

    forests to control insects and understory vegetation;
    rights-of-way along railroads and under electric wires to control vegetation;
    boat hulls to control fouling organisms;
    houses, schools, and commercial and office buildings to control insects, rodents, and fungi;
    landscapes, parks, and recreational areas to control weeds, insects, and disease pests;
    aquatic sites to control mosquitoes and weeds;
    wood products to control wood-destroying organisms;
    food preparation areas to control insects and rodents;
    human skin to kill or repel insects;
    household pets to control fleas and ticks; and
    livestock to control  insects and other pests.

                        When used properly, pesticides can benefit humans and the environment. Pesticides control
                        important crop pests, ensuring a plentiful and diverse food supply. They prevent disease in
                        humans and animals, and control pests that infest homes, schools, hospitals,food warehouses, and
                        other buildings.

                        The remainder of this section provides an overview of the regulation of pesticides, effects of pesti-
                        cidal formulations on potential absorption into the body, and patterns of exposure to pesticides.


                        Regulatory Context

                        In the United States, the Environmental Protection Agency (EPA) is responsible for regulation of
                        pesticides.  Pesticides may only be sold in the U.S. if EPA has reviewed and approved the manufac-
                        turer's application for registration, and determined that use of the product will not present an
                        unreasonable risk to humans or the environment. A pesticide that passes EPA's scrutiny will be
                        registered for use  on specific crops or sites, and must be sold with specific label directions for how
                        the product is to be used.

                        Nearly 900 active ingredients and  more than 20,000 pesticide products are registered for use in
                        the U.S. (Aspelin and Grube, 1999). Each pesticide product consists of one or more active ingredi-
                        ents (the substance that kills or controls  the pest) and may have one or more inert ingredients
                        (substances for which no pest control claim is made). Inert ingredients are added for a number of
                        reasons, such as to make the product safer or easier to apply, or to increase the efficacy of the
                        active ingredient by making it last longer in the range of the target  pest. Inert ingredients may
                        also cause adverse effects in people and/or the environment.  As of the writing of this document,
                        inert ingredients are not required to be identified on the pesticide label, although their percentage
                        must be indicated. EPA is considering changes that would require some or all inert ingredients to
                        be identified on the label.

                        A single active ingredient may be registered for different uses - such as several different crops,
                        a yard, and a food warehouse - and the concentration, application method, and application
                        rate may differ for each use. Also, products with the same active ingredient may include differ-
                        ent inert ingredients. For most applications, such as crops, pets, and livestock, pesticide usage
12  )                   patterns are seasonal. For other uses, such as structural pest control and greenhouse situa-
                        tions, pesticide applications may continue throughout the year. Pesticides may be applied as
                        sprays, dusts, granules, baits, fumigants, injection  systems, roll-on  applications, shampoos or
                        animal dips, and other methods.

                        Each active ingredient intended for use on food must have a food tolerance established. The tol-
                        erance is the legal amount of residue that may remain in or on the food at harvest. EPA sets a spe-
                        cific tolerance for  each pesticide/crop, pesticide/meat, or pesticide/meat byproduct combination.
                        Pesticides used on food or feed crops often have a pre-harvest interval (PHI) established by EPA
                        that appears on the product label. The PHI is the amount of time that must pass before a treated
                        crop can be harvested. The PHI is  important in allowing time for the pesticide to degrade to a level
                        at or below the legal tolerance.

                        In setting a tolerance, EPA considers the  relative proportion of each food in the diet, as well as the
                        acute and chronic toxicity of the active ingredient. Differences in the foods most relied on for
                        infants and children's diets are also considered. Under the Food Quality Protection Act of 1996,

EPA was charged with reviewing all tolerances for existing pesticides within ten years to determine
that they pose a "reasonable certainty of no harm"from aggregate and cumulative exposures.
Aggregate exposure refers to exposures from all sources, including residues in food and drinking
water, occupational exposures, and incidental exposures. Cumulative exposure refers to exposure
to different pesticides that share a common mechanism of action.

Pesticides that may cause unreasonable adverse effects on humans and/or the environment even
when used according to label directions are classified by EPA as restricted use pesticides (RUP).
These products may be purchased and used only by certified applicators, or by someone under
the supervision of a certified applicator. In order to become certified, applicators must receive
instruction in the proper use of RUPs and, in most states, pass a written examination.  By federal
law, all pesticides not classified as RUP are available for sale to, and use by, anyone without a
requirement for special training. However, many states have stricter pesticide laws requiring train-
ing and/or certification for anyone who applies pesticides to someone else's property, regardless of
whether the product used is classified as RUP.

-------
                        About three-fourths of U.S. households use pesticides (Aspelin and Grube, 1999). Few homeown-
                        ers who use pesticides themselves have received any training. Because products can be purchased
                        at grocery stores, hardware stores, and pharmacies, consumers may assume that the products they
                        use themselves do not pose potential hazards to health or the environment.  In fact, most products
                        marketed for the homeowner contain the same active and inert ingredients as those for commer-
                        cial markets, although usually at lower concentrations.

                        Pesticides are designed to be toxic to the pests they control, but they may also pose risks to
                        humans and wildlife. Therefore, it is extremely important that pesticides be used only in strict
                        accordance with the label. A pesticide should never be used  on a crop, plant, or site for which it is
                        not labeled, and should never be applied more frequently or  at a higher rate  than the label allows.
                        Potential risks can be minimized by choosing alternative measures when feasible and by using
                        pesticides  sparingly. When applying pesticides, care should be given to wearing the proper pro-
                        tective gear (as indicated on the label), and applying, storing, and disposing of pesticides properly.
                        Consideration should also be given to the presence of children  in the area. Children are more apt
                        to have extended contact with ground level surfaces and may have extended contact with pets.
                        Spot treatments, directed or crack and crevice sprays, baits, gels, and pastes pose less potential for
                        exposure than broadcast treatments.


                        Exposure and  Absorption

                        There are three main routes of exposure: oral, inhalation, and dermal. (Eye exposure is considered a
                        special type of dermal exposure.)  Most pesticide active ingredients can be absorbed to some extent
                        by all three routes, but the formulation of a product has a large effect on potential absorption:

                        •  Emulsifiable concentrates (liquid  active ingredient with one or more petroleum-based solvents
                            and an agent that allows the product to form an emulsion when mixed with water) and ultra-
                            low-volume concentrates (products that may approach 100% active ingredient and are
                            designed to be used as is or diluted with only very small quantities of water) are easily absorbed
                            through the skin.

                        •  Wettable powders (dry,finely ground formulations designed to be mixed with water) are less
14  )                       easily  absorbed than emulsifiable  concentrates and other liquid pesticide formulations, but
                            the powder may be inhaled during the mixing/loading process.

                        •  Fumigants (pesticides that form poisonous gases when  applied) are highly toxic to humans
                            and all other living organisms.  Some active ingredients are liquids when packaged under high
                            pressure but change to gases when released. Others are volatile liquids  when enclosed in an
                            ordinary container and so are not  formulated under pressure.  Still others are solids that
                            release gases when applied under conditions of high humidity or in the  presence of water
                            vapor. Fumigants can injure workers severely through inhalation and dermal exposure even in
                            a short period of exposure. They require the use of specialized protective equipment, includ-
                            ing respirators.

                        •  Aerosols (typically, low percentage of active ingredient sprayed out as a fine mist or fog) are
                            difficult to contain on site and are easily inhaled.
                                Extensive resources on pesticides can be found at www.neetf.org/Health/Resources/healthcare.htm

-------
    Dusts (typically, a low percentage of active ingredient plus a very fine, dry, inert carrier made
    from talc, chalk, clay, nut hulls, or volcanic ash) are applied as dry material. Dusts are less easily
    absorbed through the skin but are easily inhaled. Some dusts, such as sulfur, contain high lev-
    els of active ingredient. Sulfur is one of the most heavily used pesticides in California and has
    been responsible for the highest number of pesticide-related illnesses/injuries there.

    Granules (low percentage of active ingredient with larger, heavier absorptive materials such
    as clay, corn cobs, or walnut shells forming the carrier) are also applied dry but pose less risk of
    inhalation.

    Baits (low percentage of active ingredient mixed with food or another pest-attractive substance)
    may pose an ingestion hazard  if they are placed where children or pets can access them.
Patterns of Exposure

Three types of exposure patterns are considered here: occupational, incidental, and intentional exposures.

Occupational  Exposures
People who work in manufacturing or distribution plants for pesticide products have the most
potential exposure to pesticides, but they often have relatively low actual exposure as a result of the
installation of engineering controls at the facilities and use of personal protective equipment
(PPE). Wettable powders and most liquid pesticide products, except those specifically designed for
use by homeowners, require dilution with water, oil, or other solvent prior to application.Those who
mix and load the concentrates into the application equipment also have a high potential for expo-
sure, especially if they do not wear the PPE designated on the product label. Farm workers, migrant
laborers, and others who must reenter treated areas to perform tasks such as cultivation, harvest,
irrigation, and equipment maintenance, may be exposed to pesticide residues remaining on  the
plants, but their jobs may require them to spend more time in treated areas than the applicator.

Since the majority of the pesticide applicator work force is overwhelmingly male, there are few
studies of women exposed to pesticides at work.  Women who work with pesticides may want to
consider switching to other tasks, if possible, at least during the first trimester of pregnancy, or
should maximize their use of personal protective clothing.

EPA's Worker Protection Standard is the federal regulation that applies to agricultural pesticide
handlers and field workers.  It includes requirements for: posted warnings about pesticide applica-
tions, use of personal protective equipment  (PPE), restrictions on  re-entry into treated areas,
decontamination, emergency medical assistance, and pesticide safety training.

To keep exposures at safe levels, the pesticide product label specifies whether PPE must be worn; the
length of time that workers must wait after treatment before reentering a treated area without PPE
(called the restricted entry interval or REI);and whether training is required for workers and pesti-
cide handlers on farms, forests, greenhouses, and nurseries. As of the writing of this document, the
REI applies only to workers, not to the general public. EPA is currently considering instituting sepa-
rate REIs for others, including, for example, consumers who enter treated "pick-your-own" operations.
The rationale is that workers may be in the field eight hours per day for many days, while a consumer
would only be in  the field for a short period of time. Thus, the exposure potential for workers is much
greater than for consumers, and the REI established for each type of reentry might differ.

-------
                        The type of equipment used in applying pesticides provides different opportunities for exposure.
                        The selection of equipment varies with the crop or site, the formulation of the product, the pest
                        being targeted, the pesticide chosen, and the economic situation of the applicator or business.
                        Airplanes and helicopters, tractor-mounted sprayers, backpack sprayers, canister sprayers (com-
                        monly referred to as B&G type), granular spreaders, and other equipment may be used. Some
                        application equipment, such as closed cab systems where the operator is separated from the sur-
                        rounding environment, provides very good protection from exposure. Sometimes pesticides can
                        be loaded through closed systems, where there is very little opportunity for exposure of the
                        mixer/loader. Many structural applications of liquid pesticides call for crack and crevice treatment,
                        i.e., a stream of pesticide is directed into the angles formed where floors and walls meet or other
                        such corners along which pests run, rather than a broadcast or space spray. Homeowners typically
                        have the least specialized application equipment, but they usually apply dilute materials.

                        Many types of personal protective equipment are available, and label directions specify what
                        equipment must be worn when performing specific tasks, such as mixing and loading, applying, or
                        reentering treated areas.  In general, the hands and forearms receive the most exposure.
                        Depending on the application equipment, splashback may occur to the lower legs, drift may fall on
                        the head and ears, or a vortex effect may be generated, resulting in contamination of the back of
                        the neck. A full protective suit, gloves, respirator, hood, and boots, while providing excellent pesti-
                        cide protection, constitutes a very hot outfit and may present a heat stress hazard.  Applicators
                        may also be overexposed if equipment  is not properly maintained, e.g., when respirator filters are
J?                       not changed often enough.

-Q
                        Incidental Exposures
                        Outside of occupational exposures, people may be exposed to pesticides through residues in foods
                        and water; in and around their apartment buildings, homes, and yards; in their office buildings,
                        schools, and public buildings; and at recreational areas. National attention is focusing interest on
                        integrated pest management (IPM) strategies rather than relying solely on conventional pesticide
                        treatments in and around schools and public buildings. Long utilized in many agricultural systems,
                        IPM combines physical, cultural, biological, and other means of pest control as well as the use of
                        pesticides to minimize the potential adverse effects on human health and the environment. IPM
                        considers aspects such as pest detection, quantification of threshold levels for treatment, placement
                        of pesticide, and timing of applications in the interests of maximizing crop yield, aesthetic benefits,
                        and public health. Pesticides may be needed,for instance, to control cockroaches and rodents in
                        school cafeterias, but they may be applied as baits contained in bait stations, with little opportunity
                        for exposure of children and staff. Herbicides are frequently needed to control weeds on athletic
                        fields to prevent potential injuries associated with uneven playing surfaces, but they may be
                        applied as spot treatments rather than broadcast applications.

                        Many homeowners have herbicides and fungicides applied to their lawns throughout the growing
                        season either by themselves or by commercial firms.  Consumers also use insecticides, herbicides,
                        and fungicides on their own fruit and vegetable gardens and inside their homes and apartments.
                        Because members of the general public do not have  special training or knowledge about the
                        proper use of pesticides, they may be more  likely to misuse pesticides than trained commercial
                        applicators. They may use a pesticide at a higher rate or more often than the label allows, or not
                        use PPE to minimize exposure.

                        Another problem is use of a pesticide on a site for which the product is not registered, e.g., applica-
                        tion of pesticides labeled for use on ornamentals to vegetable and fruit gardens, or use of a  pesti-

cide labeled for outdoor application only to areas inside homes or apartments. Some products are
not registered for additional sites only because there has been no particular need for them (for
instance, if more effective products already exist for such use), but in other cases, the product is
not registered for a particular site because it would present a hazard. A common source of acci-
dental exposure in the home is improper storage of household pesticides, in areas accessible to
children. Children and others have also been injured when empty pesticide containers have been
re-used for other purposes, as residues remain in the containers.

Infants, children, the elderly, and those with compromised immune systems are at special risk if
overexposed to pesticides. Children incur more risk than adults due to the immature nature of
their immune system, larger surface area to body weight ration, higher metabolic rate, different
diet patterns and activities, different exposure profiles, and hormonal changes at puberty.

Intentional Exposures
Suicide attempts, primarily through ingestion, have accounted for deaths and serious injuries. A
total of 808 cases of suicide attempts involving pesticides were reported to Poison Control Centers
in 1995 (Litovitz et al, 1996). Pesticides used in suicide attempts are often those commonly found
in homes or on  farms.

Pesticides are thought to be a possible choice for terrorists. Even products not considered to be
highly acutely toxic could disrupt the infrastructure and/or cause panic if introduced into water
sources, sprayed over populated areas, or otherwise misused.

                      Pesticide  Competency  Guidelines  for
                      Medical  and  Nursing  Education
                      Content, Insertion Points, and Resources for Educational Curricula
                      The Pesticide Education Competencies outlined in this document are intended to apply to medical
                      and nursing schools as guidelines in training students to recognize, manage, and prevent pesti-
                      cide-related illness. The guidelines laid out below are intended as an accompaniment to the
                      Recognition and Manaqcment of Pesticide Poisonings (U.S. EPA, 1999) handbook for health profes-
                      sionals.

                      The five competencies (see list on next page) were developed as part of the Draft Implementation
                      Plan (NEETF, 2000) of the National Strategies for Health Care Providers: Pesticides Initiative. An initial
                      start at defining competencies was carried out by a subgroup of the Education Workgroup in May
                      1999, and was further elaborated in July 1999 by a small committee. This set of five competencies
                      was accepted by the full Education Workgroup. They are derived from a combination of recom-
n                     mendations from the Institute of Medicine for incorporating environmental health into medicine
3                     and nursing curricula. Competency I, Knowledge and Concepts of Pesticides, is considered the
"
                      most important and basic level that should be incorporated into all curricula as a top priority.
                      For each competency area, we specify the content of the information to be learned, identify points
                      in the curriculum where this information might be inserted, and suggest resources to consult. An
ฐ-                     asterisk (*) denotes material for residents and nurse practitioner students over and above that of
                      the undergraduate.

                      We strongly recommend that pesticide content be integrated into existing adult health, pediatric,
                      research, ethical/legal units of instruction and community health nursing courses, both didactic
                      and clinical. This can be done, for example, by using pesticides to enhance existing case studies, or
18   )                  as exemplars. In suggesting points of insertion into the curriculum, we have included such compo-
                      nents as environmental or preventive medicine electives, public sector medicine courses, etc.
                      These serve only as examples; many schools will have other courses or departments that the mate-
                      rial could fit into equally well, such as Problem-Based Learning.

1-1 b. Understand the broad spectrum of chemicals classified as pesticides and
their areas of use.

Content

The student should be aware of various types of pesticides, especially the following categories and
selected agents within each category. Students should be aware that brand names for pesticide
products change from year to year, therefore the focus should be on active ingredients.

•  Insecticides

    I   Agents that inhibit cholinesterase: organophosphates and n-methyl carbamates
    I   Pyrethrins (ocloresin extract of chrysanthemum) and pyrethroids (the synthetic derivative
        of natural pyrethrins. A clinically recognizable example of a pyrethroid is permethrin
        (Nixฎ, Elimiteฎ); however, there are many other brand names of permethrin, and many
        other pyrethroids.
        Organochlorines
        DEET
        Boric Acid
        Fluorides
        Nicotine (There were still reports of toxicity in the 1990s from old stores of nicotine.)
        Arsenicals (Rarely used anymore, with the exception of some ant bait stations.)

    Herbicides

    I   Chlorophenoxy herbicides (2-4D, mecoprop are both widely available)
    I   Paraquat and diquat
    I   Pentachlorophenol and dinitrocresol (wood preservatives)
    I   Copper chromium arsenate (Primary source of wood preservative for decks, fences, and
        children's wood playground sets - discontinued in 2003.)

    Fumigants

    I   Include: cyanide, 1,3-dichloropropane, metam-sodium, methylbromide, naphthalene,
        phosphine gas (from aluminum phosphide)
    I   Accidental dermal exposure and inhalation, especially after premature re-entry, can cause
        severe toxicity. Most fatalities are due to suicidal ingestion, because of the high concen-
        tration of exposure.

    Rodenticides

    I   Warfarin-related compounds: warfarin, coumarins, brodifacoum, difenacoum (so-called
        "super warfarins")
    I   Others: thallium, zinc phosphide, sodium fluoroacetate

    Fungicides

    I   Include: hexachlorobenzene, thiram, maneb, methylmercury compounds
                                Extensive resources on pesticides can be found at www.neetf org/Health/Resources/healthcare.htm

-------
•   Disinfectants

    I   Agents used for sanitization and sterilization in the home and hospital
    I   Registered as pesticides by the U.S. EPA
    I   Examples include alcohols, chlorhexidine, hypochlorites, iodines, phenols, and pine oil.


1-1 c.  Understand mechanisms and pathways of exposure.

Content

•   Know the most common patterns of exposure:

    I   Unintentional (common exposure pattern in children)
        I   For acute poisoning, pathway is generally intestinal absorption from unintentional
            ingestion.
        I   Inhalation exposure and dermal from surrounding environment
        I   Hand to mouth activity in children

    I   Occupational

        I   Inhalation is a common pathway.                                                                      a
        I   Dermal exposure is important, especially for pesticide applications.
        I   Ingestion is less common in the occupational setting, but can occur through failure to
            wear protective gloves and following poor hygiene practices.

        Intentional (suicide attempt/intentional abuse)
                                                                                                              o
        I   Ingestion is primary pathway.
        I   Inhalation is another pathway, although primary agents of abuse in this manner are
            non-pesticide chemicals (aromatic solvents).
    Know the biochemical mechanism of action for organophosphates/ carbamates.
                                                                                                              
-------

                        *l-1d. Understand temporal relationship between exposure and symptom.

                        Content

                        •   Know that onset of symptoms of acute poisoning will occur shortly (within 24-48 hours) after
                            exposure.

                        •   Know that some chronic symptoms may follow an acute exposure, such as organophosphate-
                            induced delayed neuropathy with onset a few weeks after exposure.

                        •   Know that in cases of continued but lower level exposure (chronic or subacute exposure),
                            symptoms may present much later. Examples include possible links to cancer following long-
                            term pesticide exposure.

                        Content
*l-1e.  Understand advanced toxicology, specifically related to organophosphates,
carbamates, and pyrethroids.
                            Know that cholinesterase inhibition is readily and spontaneously reversible with carbamate
                            poisoning.  Poisoning due to carbamates therefore does not require the use of pralidoxime.
                            However, cholinesterase inhibition due to organophosphate poisoning is less reversible. The
                            enzyme can be reactivated by pralidoxime, especially in the first 48 hours following
                            organophosphate poisoning.
o                       •   Know that pyrethroids are rapidly metabolized in the mammalian liver, accounting for their
                            relatively lower toxicity than organophosphates.

                        •   Know that cyano-pyrethroids are more toxic than other pyrethroids.

                        plays to potential hazards and exposures.

                        Content

                        •   The student should know about the common pesticide hazards associated with major rural
                            and urban industries, occupations, and avocations, including commercial agriculture,farming,
                            grounds keeping, plant nursery maintenance, general lawn care, structural pest control / exter-
                            minators, parks, playgrounds, home or apartment yards, in-house treatments for pests (e.g.,
                            ants, roaches), home and gardens, schools and day care centers.

                        •   Numerous pesticides are used for public health protection, including water purification,
                            sewage treatment, vector control.
o
                        ~   Be aware that the vast majority (80-90%) of pesticides produced are used for commercial agri-
                            culture; the remainder are used for structural pest control, horticulture, and consumer home
                            and garden purposes.

                            Be aware that health  care professionals typically use and are exposed to a large number of
                            registered pesticides  on a regular basis.

                            Understand that children are at risk for greater pesticide exposure from residuals in food than
n                          are adults due to greater consumption per kilogram of body weight, and that prevention of
                            this excess exposure  is addressed by the Food Quality Protection Act of 1996.

                        l-2b. Identify risk factors for occupational pesticide exposures.

                        Content

                        •  Understand that commercial preparations of pesticides may be more concentrated, and there-
                            fore pose greater risk to someone in an occupational setting (particularly manufacturing) than
                            the use of a diluted final product.

                        •  Understand that highest risk of exposure is faced by individuals working in agricultural pest
                            control operations: mixing, loading, applying, and flagging. Mixers and loaders are exposed to
                            concentrated pesticides and large volumes.
                                Extensive resources on pesticides can be found at www neetf.org/Health/Resources/healthcare.htm

-------
•  Understand strategies for reducing the risk of exposure, including engineering controls, such
    as closed systems for loading pesticides into tanks, and correct use of personal protective
    clothing and devices.

•  Know that pesticide handlers and workers on farms, forests, greenhouses, and nurseries are
    required to be supplied with appropriate protective gear by their employers.

•  Understand that pregnant women who work with pesticides are at high risk and should con-
    sider switching to other tasks, if possible, at least during the first trimester of pregnancy, or
    should maximize their use of personal protective clothing.

•  Understand that workers are at risk of exposure if insufficient time is allowed before re-entry
    to treated fields.

•  Understand need for proper removal and handling of contaminated clothing and showering
    prior to going home to reduce risk of exposure to residuals on clothing and skin.


l-2c. Identify risk factors for pesticide exposures at home.

Content

•  Understand that women, especially those who are pregnant, and children of farming families
    are vulnerable to pesticide exposure even if they don't work in the fields. Migrant workers
    and their families may also suffer from poor living conditions, lack of command of the English
    language, and sporadic medical care.

•  Know that homes located near farmlands may constitute a particular hazard (above the base-
    line risks of personal pesticide application to yards).

•  Know that children family members on farms are at risk for exposure to concentrated agents
    and old supplies of chemicals that are no longer used. Children playing in or near the fields
    while their parents work are at risk for exposure to pesticides.                                                     E
    Emphasize to families that care should be taken to reduce exposure to pesticides in areas
    where food is prepared and consumed, and in children's play areas.

    Be aware that pesticides used by consumers for home and garden are often nearly identical in
    formulation as those used by professional applicators or differ only in reduced strength of
    active ingredient.

    Be aware that pesticide residues are implicated in chemical sensitivities reported by patients
    who may experience symptoms in multiple systems in response to exposures to chemicals
    and environmental agents widely tolerated by a majority of people.

    Know that children incur more risk than adults due to the immature nature of their immune
    system, larger surface area to body weight ratio, higher metabolic rate, different diet patterns
    and activities, different exposure profiles, and hormonal changes at puberty.

                            Be aware that children are more apt to have extended contact with ground level surfaces and
                            may have extended contact with pets. Properly applied spot treatments, directed or crack and
                            crevice sprays, baits, gels, and pastes pose less potential for exposure than broadcast treat-
                            ments.

                            Know that contamination of food, clothing, and other objects can occur through improper
                            application of pesticides in homes, or  if items are not removed or covered prior to treatment
                            of the area.

                            Know that improper practices, including use of food or drink containers to store pesticides,
                            reuse of empty pesticide containers, and failure to lock pesticides away from children, have
                            resulted in serious illnesses and injuries to children.

                            Recognize that consumers generally have less education and training on how to properly
                            apply pesticides than farmers or commercial applicators.

o                       •  Be aware that residues may be carried into homes on shoes  worn across treated surfaces
73                           (lawns) or on clothing worn to apply pesticides.

I   Establishes a single, health-based standard for all pesticide residues in food.
I   Requires a re-evaluation of all tolerances (maximum amount of pesticide allowed on food)
    by August 2006.                                                                                        0
I   Requires that EPA use an additional 10-fold safety margin when setting standards for pes-
    ticides on foods to protect children, and allows EPA to use a different margin of safety
    only if, on the basis of reliable data, such a margin will be safe for children.
i   Requires that EPA ensure that there is a reasonable certainty that no harm will result to
    infants and children from aggregate exposure to the pesticide  residue (including from
    other sources such as water, residential, etc.).
I   Requires that EPA consider the cumulative effects from all pesticides that share a common
    mechanism of action.
I   Provides certain right-to-know provisions for consumers.

Competency  II:
Diagnosis  and  Assessment
11-1.  Environmental History.  Be able to take  an environmental history.

When considering taking an environmental history related to pesticide exposure, it is useful to
compare it to the chances of finding relatively uncommon diseases in a lifetime of general prac-
tice. Although one may obtain thousands of complete blood counts to find one case of childhood
leukemia, we are taught to include such illnesses in a differential diagnosis. If we don't consider
the uncommon illness in the diagnosis, one day it might be missed. Similarly, if pesticide poison-
ing is not considered in a patient's differential diagnosis, it will surely be missed.

Content

       www.phys.ksu.edu/area/jrm/Safety/msds.html
    I   Agency for Toxic Substances Disease Registry (ATSDR) (www.atsdr.cdc.gov)
    I   Pesticide manufacturer: Contact information should be on the label, or go to:
       http://npic.orst.edu/manuf.htm

•   Be able to complete a detailed environmental history for the adult patient when indicated, to
    include the following elements:

    I   Occupation, including length of time on job, nature of work, involvement with hazardous
       materials, use of protective equipment, habits at worksite (eating, smoking), and prior jobs
    I   Home environment, including presence of or use of pesticides in house, lawn, garden; use
       on pets; storage of pesticides; location of home in relation to industries, dump sites, farms
       Source of drinking water
       Food sources
       Relocation of home due to health problems
       Source of heat in home (e.g., wood stove)
       New/recent construction or new materials (e.g., carpets)
       Medical condition and  symptoms, including temporal relationship to any given place or
       time, others with similar problems (co-worker or family member)
    I   Use of tobacco, alcohol, other drugs (illegal, prescription, and over-the-counter), constant
       exposure to second-hand smoke
    I   Recreational activities and hobbies of the patient or family

    Be able to complete a detailed environmental history for the pediatric patient, to include the
    following elements. (Under most circumstances, similar items in the adult history should  be
    covered, from the child's perspective.)

                             I    Do you feel sick while in the fields?
                             I    Were the fields wet when you were picking? (Note: Dry fields can be a source of residues
                                 and are potentially hazardous with certain crops such as citrus, grapes.)
                             I    Do your children play in the fields?

3                              >   Children are much more likely to present with lethargy, coma, seizures than adults
                               I   Other typical cholinergic signs, especially the hyper-secretory signs, were found less
                                   likely to occur at initial presentation in several case series

                            I   *Chronic pesticide toxicity may go unrecognized because of failure to obtain a thorough
                               exposure history. Some exposures are complex, signs and symptoms are nonspecific, and
                               may be similar to other chronic illnesses. Consultation with specialists may be indicated
                               for timely or optimal diagnosis and treatment.
                            I   Know what organophosphate-induced delayed neuropathy (OPIDN) is:

                               I   Chiefly manifested by weakness, paralysis, and paresthesias, especially of lower
                                   extremities
                               I   Other symptoms of chronic toxicity to organophosphates may include headache,
                                   blurred vision, muscle weakness, depression, memory and concentration problems,
                                   irritability, and intolerance to selected chemicals

38   I                   •  Pyrethroids
                                Know that within the class of pyrethroids, the sub-category of cyano-pyrethroids is more toxic.
                                Know that the most severe toxicity is to the central nervous system, but that it occurs less
                                frequently than other signs and symptoms.
                                Seizures and disturbed level of consciousness are the chief signs.
                                Know that paresthesias are a common presenting sign.
                                Know that sensitization and allergic reactions also have been reported.
                                *Know that several additional signs and symptoms may mimic organophosphate toxicity:

                                I  Vomiting and diarrhea
                                >  Salivation and pulmonary edema
                                I  Muscle fasciculations

                            I   *Know that pyrethroid poisoning has been misdiagnosed as organophosphate poisoning

                       MM. Treatment:  Be able to effectively treat health conditions  related
                       to  pesticide over-exposures.

                       Content (Medicine)

                       •  Know that supportive therapy is often the mainstay in treating the pesticide-poisoned patient.

 in
                          I   *Be able to intubate the patient and provide emergency ventilation (residents, selected
                              advance practice nurses)
                          >   *Understand pesticide-specific instances with regard to 02:

                              >   Diquat / Paraquat: Oxygen is contraindicated in the early stages due to progressive
 3                                oxygen toxicity to lung tissue.
                          Understand principles of gastrointestinal decontamination:
                          I   Know the uses, indications, and contraindications for each of the following: syrup of
                              ipecac, gastric lavage, catharsis, & activated charcoal.
                          )   Know that ipecac is no longer recommended for routine use in most poisonings.
                          ป   *Know proper dosage of activated charcoal.
                          I   *Know that if a second dose of activated charcoal is needed in children, it should be with-
40                            out a cathartic to avoid sudden electrolyte shifts.
                       •  Understand principles of seizure management:

                          I   Diazepam is used in many of the reported pesticide poisonings including organochlorines
                              and others.
                          I   Lorazepam  is now being recognized as the drug of choice for status epilepticus, although
                              there are few reports of its use with certain pesticides.
                          I   *Know that with organochlorine poisoning, seizures can be refractory and may require
                              several medications and possibly pentobarbital coma.

                       •  *Be able to provide necessary cardiac life support.

                       •  Understand that decontamination, life support, and emergency care may need to be provid-
                          ed concurrently.

                       * An asterisk denotes material for residents and nurse practitioner students over and above that of the undergraduate.

    Know that many signs and symptoms are non-specific and many agents have no specific anti-
    dotal treatment.

    Understand special treatments required for certain pesticides:

    I   Organophosphates and Carbamates

        I   Know that tissue oxygenation must be improved as much as possible prior to giving
            atropine.
        I   *Know required atropine dose and dosing intervals.  Be aware that the dose for
            cholinesterase-inhibiting insecticides is much higher than that for cardiac resuscitation.
        I   *Know the indications for pralidoxime.
        I   *Know that pralidoxime is usually not needed for carbamates because the enzyme-
            pesticide  complex rapidly dissociates; therefore atropine alone is effective.

    I   Pyrethroids

        >   Be able to provide supportive therapy.
        >   *Know that Vitamin E oil preparations may prevent or stop paresthesias.                                   cc-
        I   Know that initial chelation is performed using dimercaprol (BAL) as an intramuscular
            injection.
        I   After gastrointestinal tract is free of arsenic, one may consider an oral chelating agent
            such as DMSA ("Succimer"), which is available in the U.S. but not labeled for this use.

        *0rganomercury Compounds (fungicides)

        I   DMSA ("Succimer") is probably the most effective agent available in the U.S.

        *Hydrogen Cyanide and Acrylonitrile (transformed to hydrogen cyanide)
                                                                                                                TJ

    I   *Rodenticides (specifically "superwarfarins" such as brodifacoum)

        >   For ingestion larger than about 1 mouthful, prothrombin time (PT) is currently recom-
            mended at 24 to 48 hours post-ingestion.
        I   More recent data suggest that if a known quantity (small amount) is unintentionally
            ingested, PT measurement may not be necessary.
        I   Phytonadione (vitamin K1) is given for an elevated PT or signs of bleeding.
        I   If taken during the preceding 15 days, determine patient's PT and give vitamin K1
            intramuscularly if PT is significantly prolonged.
        I   Intravenous vitamin K1 should be reserved for patients with active bleeding only, due
            to potential severe side effects.

-------
                                I   Be aware that PT prolongation and bleeding are much more likely in cases of inten-
                                    tional ingestion, and that due to a very long half-life of superwarfarins, PT prolonga-
                                    tion may persist for months.

                             I   *Sodium chlorate and cyanide can result in methemoglobinemia.

                                I   Know that methylene blue is indicated when about 25-30% of hemoglobin has con-
                                    verted to methemoglobin.
                                I   The dose is 0.1 ml/kg body weight of 1 % solution over 10 minutes.
                                >   Know that an exchange transfusion may enhance clearance in severe cases.

                             Chronic effects: Be aware of recent research on chronic effects associated with pesticides,
                             including the following (non-exhaustive) list:

                                 I    Epidemiology suggests that DDT and other agents may increase risk for breast and
                                     ovarian cancer.
                                 I    Risk factors:
