INITIAL DRAFT ADVISORY
AN IMPORTANT MESSAGE FOR PREGNANT
WOMEN, WOMEN WHO MAY BECOME PREGNANT, NURSING MOTHERS AND YOUNG CHILDREN ABOUT
THE RISKS OF MERCURY IN FISH AND SHELLFISH
Fish
and shellfish can be an important part of a balanced diet. It is a good source of high quality protein
and other nutrients and is low in fat.
However,
some fish and shellfish contain high levels of a form of mercury called
methylmercury that can harm the developing nervous system of an unborn baby or
young child. It is important for
pregnant women, women of childbearing age who may become pregnant, nursing
mothers, and young children to eat the types and amounts of fish and shellfish
that are safe, to prevent any harm from methylmercury and still enjoy the
health benefits of eating seafood. Young children should follow the same advice
as adults regarding the types of fish to eat, but should eat less because they
are smaller.
HOW DOES
MERCURY GET INTO FISH AND SHELLFISH?
Mercury
occurs naturally in the environment and it can also be released into the air
through industrial pollution. Mercury
falls from the air and can get into surface water accumulating in streams and
oceans. Bacteria in the water cause
chemical changes that transform mercury into methylmercury that can be toxic.
Fish and shellfish can absorb methylmercury as they feed on aquatic organisms.
HOW CAN YOU
AVOID LEVELS OF MERCURY THAT COULD HARM CHILDREN?
Nearly
all fish and shellfish contain trace amounts of methylmercury, which are not
harmful to humans. However, some fish
and shellfish, including those sold in grocery stores and restaurants and those
which are caught in local lakes and rivers can accumulate
more mercury than others and therefore pose the greatest risk to people who eat
them.
WHAT FISH AND
SHELLFISH PURCHASED IN A GROCERY STORE OR RESTAURANT SHOULD YOU AVOID?
You
should not eat these fish that can contain high levels of methylmercury.
Ø
Shark
Ø
Swordfish
Ø
King mackerel
Ø
Tilefish
IS IT ALL
RIGHT TO EAT OTHER FISH AND SHELLFISH PURCHASED FROM GROCERY STORES OR
RESTAURANTS?
Yes.
As long as you select a variety of other kinds of fish and shellfish
purchased in stores and restaurants, it is safe to enjoy eating them as part of
a healthful diet. It is safe for adults
to eat up to 12 ounces per week (usually 2-3 meals per week). Children should eat lesser amounts depending
on their size.
It is important to choose a variety of
different species each week. Choose a
combination from shellfish, canned fish, smaller ocean fish, or farmed-raised
fish. Some of the most commonly
consumed fish and shellfish that have low levels of mercury are shrimp, salmon,
pollock, farm-raised catfish, and light canned tuna.
Tuna is the most frequently consumed
fish in the United States. Mercury
levels in tuna vary. Unlike canned
light tuna, tuna steaks and albacore canned tuna contain higher levels of
methylmercury because they are larger fish.
WHAT ABOUT
FISH AND SHELLFISH CAUGHT BY FAMILY AND FRIENDS OR FROM LOCAL WATERS? ARE THEY
SAFE TO EAT?
Some kinds of fish and shellfish caught
in your local waters may have higher or much lower than average levels of
methylmercury. Those with lower levels may be safely eaten more frequently and
in larger amounts. Contact your state or local health department or other
appropriate food safety authority for specific consumption recommendations
about fish and shellfish caught in your local area.
If no local advice is available, adults can safely
consume up to 6 ounces (one meal) of locally caught fish and shellfish per
week. Children again should eat lesser
amounts depending on their size. If no local advice is available, do not
consume fish and shellfish bought in stores and restaurants AND fish and shell
fish bought by family and friends in the same week unless your local advisories say it is
safe to do so.
WHAT IF YOU
EAT MORE THAN THE RECOMMENDED AMOUNT OF FISH AND SHELLFISH A WEEK?
There is no harm in eating more than
the recommended amount of fish and shellfish in one week as long as you don’t
do it on a regular basis. One week’s
consumption does not change the level of methylmercury in the body much at all.
If you eat a lot of fish and shellfish one week, you can cut back the next week
or two.
SECOND DRAFT ADVISORY
ADVICE FOR WOMEN WHO ARE PREGNANT, OR WHO MIGHT BECOME
PREGNANT, AND NURSING MOTHERS, ABOUT
AVOIDING HARM TO YOUR BABY OR YOUNG CHILD FROM MERCURY IN FISH AND SHELLFISH
Fish
and shellfish can be an important part of a balance diet. It is a good source of high quality protein
and other nutrients and is low in fat.
The Food and Drug Administration and the Environmental Protection Agency
are advising pregnant women and nursing mothers to eat the types and amounts of
fish and shellfish that are safe to prevent any harm to the developing nervous
system of their baby or young child.
Since mercury may build up in your body and be there when you become pregnant, women who may become pregnant need to follow this advice
as well.
To protect your baby follow these 3 rules:
Ø Do not eat
Shark, Swordfish, King mackerel, or Tilefish.
Ø Limit your
consumption of all other fish and shellfish you buy to no more
than 12 ounces (2 to 3 meals) of fish and shellfish a week. Mix up the types of
fish and shellfish you eat and do not eat the same type of fish and shellfish
more than once a week.
Ø Check local
advisories about the safety of fish caught in your local rivers and
streams. If no advice is available,
limit consumption of fish from local waters to 6 ounces per week.
Follow these same 3 rules when feeding fish and shellfish to your young
child, but the serving sizes should be smaller.

What is
mercury?
Mercury occurs
naturally in the environment and can also be released into the air through
industrial pollution. It falls from the air and can accumulate in streams and
oceans and is turned into methylmercury in the water. It is this type of
mercury that is harmful to your baby.
Fish absorb the methylmercury as they feed in these waters and so it may
build up in the fish. It builds up more
in some types of fish than others, depending on what the fish eat, which is why
the levels in the fish vary.
Is there
methylmercury in all fish?
Nearly all
fish contain traces of methylmercury. However, larger fish that have lived
longer have the highest levels of methylmercury because they've had more time
to accumulate it. These large fish (swordfish, shark, king mackerel and
tilefish) pose the greatest risk to pregnant women. Other types of fish are
safe to eat in the amounts recommended by FDA and EPA If you want more information about the levels in various types of
fish see the FDA food safety web site. www.cfsan.fda.gov or the EPA website at www.epa.gov/ost/fish
What about
tuna?
Tuna is the
most frequently consumed fish in the United States. Mercury levels in tuna vary.
Tuna steaks and canned albacore tuna generally contain higher levels of
mercury than canned light tuna.
I'm not
pregnant - so why should I be concerned about methylmercury?
If you
regularly eat types of fish that are high in methylmercury, it can accumulate
in your blood stream over time.
Methylmercury is removed from the body naturally, but it may take over a year for the levels to drop
significantly. Thus, it may be present in a woman even before she
becomes pregnant. This is one of the reasons why women who are trying to become
pregnant should also avoid eating certain types of fish.
How could
methylmercury affect my baby or young child?
The developing
nervous system of a baby in its mother’s womb is susceptible to high levels of
methylmercury. Babies exposed to high
levels of methylmercury can develop problems such as minor delays in learning
to walk or talk. Once the baby is born
and as it gets older the risks become less and less. If you follow the advice
given by FDA and EPA you will gain the positive benefits of fish but avoid the
medical problems associated with the mercury in fish.
But I
though fish was good for me when I am pregnant.
It is in
moderation. Scientists have learnt that
some types of fish contain levels of mercury in them that may harm your unborn
child. This is why FDA and EPA are advising you to avoid certain types of fish
and eat other fish in moderation. By
eating these other types of fish in moderation you will get the benefits of
fish but avoid the harm.
Why do I need to get local advice for
locally caught fish?
Some kinds of
fish and shellfish caught in your local waters may have higher or much lower
than average levels of mercury. This depends
on the levels of mercury in the water in which the fish are caught. Those fish with lower levels may be safely
eaten more frequently and in larger amounts.
What are
“types” of fish and shellfish?
Types of fish and shellfish are identified by their common names such as albacore tuna, Atlantic salmon, cod, haddock, grouper, blue crabs, shrimp, etc.
How can
learn about local advisories?
Before you go fishing,
check your Fishing Regulations Booklet for information about local
advisories. You can also contact your
local health department for information about local advisories.
