Healthy and Green Living

Pregnant women and women considering pregnancy should not eat shark,
swordfish, king mackerel or tilefish because they could contain
enough mercury to harm an unborn infant’s nervous system, according to an FDA advisory. Young children and nursing women also should
avoid those species of fish.

The problem with these particular species of fish is that they live for a long time, giving time for higher amounts of contaminants to accumulate in their tissues, according to the FDA. The FDA notes that pregnant women can safely eat 12 ounces of other types of cooked fish each week.

Bacteria in both fresh and salt water convert mercury into methylmercury, a neurotoxic chemical that can cause brain damage, memory loss, personality change, tremors, spontaneous abortion, and damage to a developing fetus. Fish absorb and ingest the mercury and methylmercury, and store it in their tissues. Mercury is naturally occuring, but half of the mercury in the environment comes from smokestack emissions, incinerators, and coal-fired power plants.
