Which one of the following should NOT be consumed during pregnancy due to a potentially high mercury content?
B) Crawfish, shrimp, and lobster
C) Flounder and haddock
D) Salmon and trout
E) Shark and swordfish
Larger ocean fish that consume other fish may accumulate mercury levels that can cause neurologic problems when consumed, so these fish should be avoided by children and pregnant or nursing women. Shark and swordfish are among the fish with the highest mercury content. Catfish, crawfish, shrimp, lobster, flounder, haddock, salmon, and trout have the least amount of mercury.
