About the GuideAbout the Guide
The Eat Safe Fish Guide (ESF Guide) is provided by the Michigan
Department of Health and Human Services (MDHHS).
• The fish listed under each lake or river in the ESF Guide
have been tested for chemicals.
• Scientists from MDHHS test only the part of the fish
you would eat — typically the filet — to determine the
guidelines included in the ESF Guide.
• MDHHS uses the test results from the edible portions
to find the average amount of chemicals in the
fish species from that lake or river. They use this
information to determine how much fish is safe to eat
per month.
• The ESF Guide is not a rulebook. These are only
guidelines to help you make safer choices for you and
your family. You are not required to use it.
• The ESF Guide does not include rules and regulations
about catching or keeping legally-sized fish.
• The ESF Guide provides advice for the size range of fish
that are typically caught and eaten.
Michigan DNR Fishing Laws
You should get a copy of the DNR Michigan
Fishing Guide when you purchase your fishing
license. If you lost your Fishing Guide or
have other questions about fishing legally,
please call the Michigan Department of
Natural Resources at 1-517-373-1230 or visit
Michigan.gov/Fishing.
Questions About Eating Safe Fish?
If you have questions about choosing safer fish
to eat or would like the ESF Guide for another
region, please call the Michigan Department of
Health and Human Services at 800-648-6942
or visit Michigan.gov/EatSafeFish.

Choosing Safer FishChoosing Safer Fish
The guidelines in the ESF Guide are set to be safe for everyone.
This includes children, people who are pregnant or breaseeding,
and people who have health problems, like cancer or diabetes.
But the ESF Guide is also for healthy adults who want to avoid
getting too many chemicals in their bodies. Polychlorinated
biphenyls (PCBs), dioxins, and perfluorooctane sulfonic acid (PFOS)
are linked to cancer and other illnesses. Mercury can cause damage
to your brain and nerves. MDHHS uses chemical limits in the ESF
Guide that will protect everyone who eats fish.

How much is MI Serving?
Weight of PersonWeight of Person MI Serving SizeMI Serving Size
45 pounds 2 ounces
90 pounds 4 ounces
180 pounds 8 ounces
Weigh Less?
For every 20 pounds less than the weight listed in the table,
subtract 1 ounce of sh.
For example, a 70 pound child’s MI Serving size is 3 ounces of fish.
90 pounds - 20 pounds = 70 pounds
4 ounces - 1 ounce = a MI Serving size of 3 ounces
Weigh More?
For every 20 pounds more than the weight listed in the table,
add 1 ounce of sh.
For example, a 110 pound person’s MI Serving size is 5 ounces of fish.
90 pounds + 20 pounds = 110 pounds
4 ounces + 1 ounce = a MI Serving size of 5 ounces
Are you
pregnant?
Fish is good for you and your baby! Use your
pre-pregnancy weight to find your MI Serving
size. It is best to avoid eating fish labeled as
“Limited” if you’re pregnant or breastfeeding.

Special MI Serving Categories
Do Not Eat LimitedLimited
MDHHS suggests you avoid eang all sh
listed as “Limited” because of higher levels of
chemicals if you:
• Are under the age of 15.
- or -- or -
• Have health problems, like cancer or diabetes.
- or -- or -
• Might have children in the next several years, are
currently pregnant, or are breastfeeding.
If NONE of the above apply to you, it is usually OK to eat fish
listed as “Limited” one or two mes each year.
Do Not Eat
No one should eat sh listed as
Do Not Eat, regardless of age or health.
When these fish were tested, MDHHS found very
high levels of chemicals. Eating even one meal of
these fish could possibly lead to health problems
in the future, regardless of age or health.
Finding a Balance
Sometimes a child might eat more than 2 ounces of fish, or a 180
pound adult might eat more than 8 ounces of fish, in one sitting. It’s
OK; just count the number of MI Servings you eat in that meal.
For example, let’s say the 180 pound adult
ate 16 ounces of fish during one meal. That
is two MI Servings of fish for a person of that
size. If the fish is listed as two, four, or twelve
MI Servings in the ESF Guide, they’re still
within their range. If the fish is listed as one
MI Serving per month or Limited, they might
want to avoid eating other meals of fish for a
while to give their body time to process the
chemicals.
No one should eat any amount of sh listed
as Do Not Eat in the ESF Guide.

Choose
If you eat fish often, you can use the ESF Guide to choose
the safest fish to keep and eat from any Michigan lake
or river. Is that fish limited to one or two MI Servings per
month in the ESF Guide? Use the map to find another
lake or river nearby where you can eat more!
22
Clean
When you clean your fish, try trimming away as much
of the fat as you can see. Some chemicals, like PCBs
and dioxin, are stored in the fat. If you cut out the fat,
you cut down on the chemicals in your fish. Just note,
you can’t remove mercury or PFOS from your fish by
trimming. Mercury and PFOS are stored in the meat of
the fish.
33
Cook
Not only is grilling or broiling your fish healthier than
frying, it also helps to get rid of more chemical-carrying
fat. When you cook a fish on a grate, any fat hiding
inside the filet can melt and drip away from the fish. This
removes even more of those harmful chemicals.
If you follow the 3Cs carefully, you can remove up to half of the
chemicals in your fish.
That means you can double the number of MI Servings per month, if:
• Mercury or PFOS are not listed in the “Chemical of Concern”
column.
• The MI Serving is not listed as “Limited”.
For example:

These guidelines are based on the typical amount of chemicals found in fish filets
tested from around the state. Some fish may be higher or lower. If any of these
fish are listed in the guidelines for the lake or river you are fishing in, use those
guidelines instead of statewide guidelines. The MI Servings recommendation will
be more exact for that lake or river because those filets have been tested.

FAQsFAQs
How often is the Eat Safe Fish Guide (ESF Guide) updated?
The ESF Guide is updated regularly, but due to time and funding, not all
fish from all bodies of water listed in the ESF Guide are tested every year.
If there are special problems in the area, fish may be tested more often or
sooner than planned.
PCBs, dioxin, mercury, PFOS, and other chemicals that can
be found in fish stay in our environment for a very long
time. The amount of chemicals found in the fish is not
expected to change a lot from year to year.
What part of the sh is tested for the ESF Guide?
While the entire headless, gutted smelt is tested for chemicals, for all other
fish it is only the filets of the fish that are tested for chemicals. The skin is
left on or taken off depending on common practice when cooking the fish.
The organs and head are not tested for the ESF Guide. Internal organs (liver,
fish eggs, etc.) typically have higher levels of chemicals than the filet and
shouldn’t be eaten.
Can I review the data myself?
Yes. All of the data, procedures, and scientific reports used to create the
ESF Guide are available online under Reports & Science at Michigan.gov/
EatSafeFish. If you do not have internet access, call MDHHS at 800-648-
6942, and we’ll be happy to provide you with the information.
Will I be able to tell if the sh are safe to
eat by looking at them?
No. You will not be able to see any of the chemicals,
even mercury or PFOS, in the fish. You also can’t
taste or smell the chemicals listed in the ESF Guide.
To find the chemicals, MDHHS tests the fish in a
laboratory. MDHHS only tests the part of the fish that most people eat —
typically the filets — for chemicals.
You can’t see these chemicals in the water, either. Some very clear lakes or
rivers can still have fish with higher levels of chemicals. If you eat a lot of
Michigan fish, you can check the ESF Guide to find the safest options from
the lake or river that you’re fishing.
10
Michigan.gov/EatSafeFish
Is it safe to touch a sh that has chemicals in it?
Yes. You do not need to wear gloves or worry about getting the chemicals
on you. They will not absorb into your skin from the fish.
Catch and release is almost always safe in Michigan regardless of where
you’re fishing. However, sometimes your local health department may
issue a temporary warning against touching the water - including the
fish that live in the water - because of problems like sewage overflow or
harmful algae blooms.
You can contact your local health department or visit
Egle.state.mi.us/beach/ for local warnings about water quality.
Why should I use the Eat Safe Fish Guide?
If you eat fish, you might also be eating chemicals — like mercury, PCBs,
PFOS, or dioxins. These chemicals can stay in your body for a long time.
The ESF Guide is designed to protect everybody — men, women, and
children — who eats fish on a regular basis.
Using the ESF Guide and following the MI Serving suggestions will keep
you from getting too many chemicals in your body at once. Scientists set
the limits in the ESF Guide so that you are protected from possible health
problems from the chemicals, no matter how long they stay in your body.
The ESF Guide is designed to protect any person who eats fish on a regular
basis. If you are a healthy adult who is not pregnant and only eats Michigan
fish once or twice a year from waters that are not posted with MDHHS
signs, then you don’t need to use the ESF Guide.
The S.A.F.E. fishing tips and the 3Cs in the MDHHS Eat Safe Fish in Michigan
brochure will help the occasional Michigan fish eater avoid eating too many
chemicals. Call 800-648-6942 to get a free copy of the brochure.
You may choose to eat more fish than the ESF Guide recommends. These
guidelines are not rules; it is your choice. And not everyone will get sick
from eating too many of these chemicals. The chemicals in the fish won’t
make you sick right away, either. Some people will be fine after years of
eating fish with these chemicals in them. Others can have health problems.
It is difficult to know who might get sick from the chemicals in fish and who
won’t. The ESF Guide makes it easy for you to make safer choices for you
and your family and avoid eating too many chemicals in fish.
I don’t see a sh species listed in the ESF Guide. I don’t
see my favorite shing hole. What does this mean?
Michigan is lucky to have over 11,000 lakes, rivers, and streams. Because
of that huge number, it is not possible to test every fish species from every
body of water in the state.
If you don’t see the fish species you’re going after listed in the ESF Guide
for your lake or river OR you don’t see the lake or river listed at all, see
page 9 for the Statewide Safe Fish Guidelines.

The fish species listed on the following pages have been tested
for chemicals by the Michigan Department of Health and Human
Services (MDHHS).
The guidelines issued by MDHHS are based only on the amount
of chemicals in the filet of the fish — the part that you would eat.
All fish listed here are not tested every year. Because the
chemicals found in fish don’t break down quickly, the amount of
chemicals in the fish will not change that much from year to year
and neither will the guidelines.
If you would like to review the data collected to support these
guidelines, they are available at Michigan.gov/EatSafeFish. If you
do not have access to the internet or have additional questions,
we are available at 800-648-6942, Monday-Friday, 8am-5pm.

What Are the What Are the
Chemicals of Concern?Chemicals of Concern?
The chemicals that cause Michigan’s Eat Safe Fish guidelines are DDT,
dioxins, mercury, PCBs, PFOS, selenium, and toxaphene. Many of these
chemicals were put into the environment - by accident or on purpose -
before we knew the long-term health and environmental problems they
can cause.
These chemicals can travel through the air, and they can be carried by rain
run-off and storm drains into our lakes, rivers, and wetlands. Once in the
water, the chemicals sink to the bottom and become a part of the fish food
chain. Some of these chemicals can stay in the environment, in the fish,
and in the human body for a long time.
Efforts to reduce pollution under the U.S. Clean Water Act and U.S. Clean
Air Act have cut the levels of these chemicals in the environment. In fact,
the amount of DDT, dioxins, PCBs, and toxaphene in our fish are slowly
going down. However, mercury continues to be a worldwide problem and
newer chemicals, like PFOS, might stay in the environment for a long time.
Chemical of
Concern
What is it?
Potential Health
Problems
DDT
(dichlorodiphenyl-
trichloroethane)
• was one of the first
modern insecticides
• was banned in 1972
• linked to the
development of cancer
• linked to the
development of
diabetes
Dioxins
• are not made on
purpose
• are created when
chlorine chemicals are
made or used
• can be released when
things that have
chlorine in them - like
paper or plastic - are
burned
• also can be released
from old or poorly
contained waste sites
or intentional dumping
• linked to the
development of cancer
• can harm fertility
• can harm thyroid
function

Chemical of
Concern
What is it?
Potential Health
Problems
Mercury
• is a natural element
• can be released from
smokestacks of coal-
fired power plants and
other industry
• can harm brain
development in fetuses
and children
• can harm heart function
in older adults
• can harm the immune
system
PCBs
(polychlorinated
biphenyls)
• were used in electrical
equipment - like
transformers
• were found in
hydraulic oils
• can harm brain
development in fetuses
and children
• linked to the
development of cancer
• linked to the
development of
diabetes
• can harm the immune
system
PFOS
(peruorooctane
sulfonate)
• is used for
waterproofing clothes,
in fire-fighting foams,
papers and packaging,
cleaning products, and
pesticides
• is now rarely used in
the United States
• can harm thyroid
function
• can harm brain
development in fetuses
and children
Selenium
• is a natural element
• is needed for your
body to function, but
too much is harmful
• through mining
activites, selenium-rich
rock and water were
added into waterways
• hair loss
• loss of fingernails
• fatigue
• irritability
• mild nerve damage
Toxaphene
• was an insecticide for
cotton and vegetables
and on livestock and
poultry
• was sometimes
added to lakes to kill
unwanted fish
• was banned in 1990
• can harm the immune
system
