Can I eat swordfish while pregnant?

The FDA and EPA categorize swordfish as a "Choice to Avoid" for pregnant women, those who might become pregnant, and breastfeeding mothers. This classification is based on the high concentration of methylmercury found in large, long-lived predatory fish. Methylmercury is a neurotoxin that can cross the placenta and potentially damage the developing brain and nervous system of a fetus. Even occasional consumption is discouraged because mercury accumulates in the body over time and takes months to naturally clear. While fish is an important source of omega-3 fatty acids, guidelines emphasize selecting lower-mercury alternatives to achieve nutritional benefits without the associated risks of heavy metal exposure. These recommendations remain consistent across major health organizations, including ACOG and the CDC, to ensure optimal maternal and fetal health outcomes.
