What precautions should women take to reduce these risks?

The FDA recommends that pregnant women and women of childbearing age who may become pregnant should not eat shark, swordfish, king mackerel or tilefish. FDA advises that pregnant women and women of childbearing age who may become pregnant "can safely eat 12 ounces per week of cooked fish. A typical serving size of fish is from 3 to 6 ounces. Of course, if your serving sizes are smaller, you can eat fish more frequently. You can choose shellfish, canned fish, smaller ocean fish or farm-raised fish-just pick a variety of different species." The EPA recommends that pregnant women or who may become pregnant, nursing mothers and young children should limit their consumption of fish caught by family and friends to one meal per week. Of course, all consumers and especially pregnant women should follow the basic nutritional guidelines.
