FDA Announces Advisory On Methyl Mercury In Fish

WASHINGTON, DC -- January 16, 2001 -- The Food and Drug Administration (FDA) is

announcing its advice to pregnant women and women of childbearing age who may

become pregnant on the hazard of consuming certain kinds of fish that may

contain high levels of methyl mercury.

The FDA is advising these women not to eat shark, swordfish, king mackerel, and

tilefish. As a matter of prudent public health advice, the FDA is also

recommending that nursing mothers and young children not eat these fish as well.

Fish such as shark, swordfish, king mackerel, and tilefish contain high levels

of a form of mercury called methyl mercury that may harm an unborn baby's

developing nervous system. These long-lived, larger fish that feed on smaller

fish accumulate the highest levels of methyl mercury and therefore pose the

greatest risk to the unborn child. Mercury can occur naturally in the

environment and it can be released into the air through industrial pollution and

can get into both fresh and salt water.

The FDA advisory acknowledges that seafood can be an important part of a

balanced diet for pregnant women and those of childbearing age who may become

pregnant. FDA advises these women to select a variety of other kinds of fish --

including shellfish, canned fish, smaller ocean fish or farm-raised fish -- and

that these women can safely eat 12 ounces per week of cooked fish. A typical

serving size of fish is from three to six ounces.

The FDA's Center for Food Safety and Applied Nutrition will launch a

comprehensive education program to reach pregnant women and women of

childbearing age who may become pregnant and their health care providers

concerning the hazard posed by methyl mercury to the unborn child. As one of its

priorities for fiscal year 2001, the Center will also develop our overall public

health strategy for future regulation of methyl mercury in commercial seafood.

The EPA is also issuing advice on possible mercury contamination to women and

children eating fish caught by family and friends (non-commercial fish). EPA

particularly recommends that consumers check with their state or local health

department for any additional advice on the safety of fish from nearby waters.
