Can I eat seafood during pregnancy?
Certain types of seafood are safe to eat in pregnancy in limited amounts. The concern is the amount of mercury found in seafood, which if ingested in high amounts can be harmful to your baby’s neurologic development. Fish that contain high levels of mercury (and should be avoided) are shark, tilefish, king mackerel, and swordfish. It is safe to eat other types of seafood including shellfish, up to 12 ounces per week. Albacore (white) tuna contains more mercury than canned light tuna, so you may eat up to 6 ounces of albacore tuna per week. Examples of commonly eaten seafood that are low in mercury include shrimp, canned light tuna, salmon, and catfish.
