Pregnant women can enjoy grouper as part of the three six-ounce servings of high mercury cooked seafood they eat per month. The FDA recommends a limit on the amount and kind of seafood pregnant women ingest to prevent harm to themselves and their baby caused by high levels of mercury. Grouper is in the class of fish considered to have a high amount of mercury according to the American Pregnancy Association. Additionally, pregnant women should only eat grouper if it is fully cooked. According to the FDA, pregnant women should not eat any raw or undercooked seafood and should cook seafood to at least 145 °F.
