Can eating crab legs during a pregnancy hurt the baby?

Not in general: I imagine you are concerned about mercury levels in fish. In general mild consumption of sa;t water. Fresh water and shell fish is fine. Make sure its fresh and cooked properly as improperly cooked shellfish may cause infection issues.

Not if cooked: Freshly cooked crab and lobster are safe to eat during pregnancy. Do not eat uncooked shellfish, shark, swordfish, tilefish or king mackerel due to possible bacteria and high mercury levels in the latter.

Likely not: As long as they were cooked well, there is little likihood of any harm to the baby. Also, i'm assuming you didn't eat 500 pounds of them either.The caution with fish and seafood during pregnancy is mainly related to mercury contained in them, and if you just ate them a few times in normal quantities, you did not put the baby at risk. Always cook your food well an dwash hands, esp. When pregnant!
