Is Bigeye tuna safe during pregnancy?
High-mercury fish — FDA advises not eating bigeye tuna while pregnant or breastfeeding. Swap for salmon, shrimp, cod or light tuna.
What the sources say
Bigeye tuna is on the FDA/EPA "Choices to Avoid" list (highest mercury). Mercury can harm a developing baby's brain and nervous system and passes into breast milk; cooking or trimming skin and fat does not lower it. If you've already eaten some, FDA advises choosing lower-mercury fish going forward. Lower-mercury "Best Choices" (2–3 servings a week) include salmon, shrimp, cod, sardines and canned light tuna. Canned light tuna is a Best Choice; albacore and yellowfin are Good Choices.
