Should I Eat the
Fish I Catch?
Printed on recycled paper,
A guide to healthy eating
of the fish you catch
Developed in collaboration with the Agency
for Toxic Substances and Disease Registry,
U.S. Public Health Service
Introduction
Fish are an important part of a healthy diet.
They are a lean, low-calorie source of protein.
Some sport fish caught in the nation's lakes,
rivers, oceans, and estuaries, however, may
contain chemicals that could pose health risks if
these fish are eaten in large amounts.
The purpose of this brochure is not to
discourage you from eating fish. It is intended
as a guide to help you select and prepare fish
that are low in chemical pollutants. By following
these recommendations, you and your family
can continue to enjoy the benefits of eating fish.
Fish taken from polluted waters might be
hazardous to your health. Eating fish containing
chemical pollutants may cause birth defects,
liver damage, cancer, and other serious health
problems.
Chemical pollutants in water come from many
sources. They come from factories and sewage
treatment plants that you can easily see. They
also come from sources that you can't easily see,
like chemical spills or runoff from city streets
and farm fields. Pollutants are also carried long
distances in the air.
Fish may be exposed to chemical pollutants in
the water, and the food they eat. They may take
up some of the pollutants into their bodies. The
pollutants are found in the skin, fat, internal
organs, and sometimes muscle tissue of the fish.
What can I do to reduce my health risks
from eating fish containing chemical
pollutants?
Following these steps can reduce your health
risks from eating fish containing chemical
pollutants. The rest of the brochure explains
these recommendations in more detail.
1. Look for warning signs or call your
local or state environmental health
department. Contact them before you
fish to see if any advisories are posted in
areas where you want to fish.
2. Select certain kinds and sizes of
fish for eating. Younger fish contain
fewer pollutants than older, larger fish.
Panfish feed on insects and are less likely
to build up pollutants.
3. Clean and cook your fish properly.
Proper cleaning and cooking techniques
may reduce the levels of some chemical
pollutants in the fish.
HEALTH NOTE
Advisories are different from
fishing restrictions or bans or limits.
Advisories are issued to provide
recommendations for limiting the
amount of fish to be eaten due to
levels of pollutants in the fish.

Catching Fish
How can I find out if the waters that I
fish in are polluted?
It's almost impossible to tell if a water body is
polluted simply by looking at it. However, there
are ways to find out.
First, look to see if warning signs are posted
along the water's edge. If there are signs, follow
the advice printed on them.
Second, even if you don't see warning signs,
call your local or state health or environmental
protection department and ask for their advice.
Ask them if there are any advisories on the
kinds or sizes of fish that may be eaten from the
waters where you plan to fish. You can also ask
about fishing advisories at local sporting goods
or bait shops where fishing licenses are sold.
If the waterbody has not been tested, follow
these guidelines to reduce your health risks
from eating fish that might contain small
amounts of chemical pollutants.
Some chemical pollutants, such as mercury
and RGBs, can pose greater risks to women
of child bearing age, pregnant women, nursing
mothers, and young children. This group
should be especially careful to greatly reduce or
avoid eating fish caught from polluted waters.
Trim away the skin and fatty tissue before cooking to
reduce the level of some pollutants in the fish you eat.

Do some fish contain more pollutants
than others?
Yes. You can't look at fish and tell if they contain
chemical pollutants. The only way to tell if fish
contain harmful levels of chemical pollutants is
to have them tested in a laboratory. Follow these
simple guidelines to lower the risk to your family:
• If you eat gamefish, such as lake trout,
salmon, walleye, and bass, eat the smaller,
younger fish (within legal limits). They
are less likely to contain harmful levels of
pollutants than larger, older fish.
• Eat panfish, such as bluegill, perch, stream
trout, and smelt. They feed on insects and
other aquatic life and are less likely to contain
high levels of harmful pollutants.
• Eat fewer fatty fish, such as lake trout, or fish
that feed on the bottoms of lakes and streams
such as catfish and carp. These fish are more
likely to contain higher levels of chemical
pollutants.

Cleaning Fish
Can I clean my fish to reduce the amount
of chemical pollutants that might be
present?
Yes. It's always a good idea to remove the skin, fat,
and internal organs (where harmful pollutants are
most likely to accumulate) before you cook the fish.
As an added precaution:
• Remove and throw away the head, guts,
kidneys, and the liver.
• Fillet fish and cut away the fat and skin
before you cook it.
• Clean and dress fish as soon as possible.
Can / cook my fish to reduce my health
risk from eating fish containing chemical
pollutants?
Yes. The way you cook fish can make a
difference in the kinds and amounts of chemical
pollutants remaining in the fish. Fish should be
properly prepared and grilled, baked, or broiled.
By letting the fat drain away, you can remove
pollutants stored in the fatty parts of the fish.
Added precautions include:
• Avoid or reduce the amount of fish drippings
or broth that you use to flavor the meal.
These drippings may contain higher levels of
pollutants.
• Eat less fried or deep fat-fried fish because
frying seals any chemical pollutants that
might be in the fish's fat into the portion that
you will eat.
• If you like smoked fish, it is best to fillet the
fish and remove the skin before the fish is
smoked.
HEALTH NOTE
Mercury is found throughout the tissue in fish,
so these cleaning and cooking techniques
will not reduce the amount of mercury in a
meal offish.
