Last year the FDA issued a consumer advisory about the risks of mercury in fish consumed during pregnancy The advisory described seafood as an "important part" of a pregnant women's diet but listed four types--shark, swordfish, king mackerel, and tilefish--that should be avoided by pregnant and lactating women and women of childbearing age who may become pregnant because the fish have high levels of methylmercury.
That advisory came under fire from the Center. for Science in the Public Interest, a Washington-based consumer advocacy group. The CSPI charged that tuna in the form of steaks or sushi can contain methylmercury levels that exceed the action level set by the FDA. Canned tuna contains much lower levels of methylmercury but can still be problematic if eaten in large quantities, they said.
