Studies show that mercury inhibits Ca²⁺ATPase in the brain, heart, and skeletal muscles.
Practice responsible seafood consumption.
Lowest levels of mercury (eat as desired): catfish, clams, crab, flounder, haddock, oyster, pollock, wild salmon, sardine, scallops, and shrimp
Moderate (eat maximum six times per month): striped bass, carp, cod, lobster, mahi mahi, perch, skate, and snapper
Higher mercury (eat maximum three times per month): croker, halibut, Spanish mackerel, perch, sable fish, Chilean sea bass, and albacore/yellowfin tuna.
Highest mercury (avoid completely): bluefish, grouper, king mackerel, marlin, orange roughie, and swordfish.
For expectant and nursing mothers and young children, reduce fish intake per FDA and EPA guidelines.
These guidelines recommend complete avoidance of shark, swordfish, king mackerel, or tilefish, and a limited intake of other seafood, such as shrimp, canned light tuna, salmon, pollock, and catfish to 12 oz a week (two average meals).
