Can you remove mercury from fish?

Cooking does not remove mercury from fish because the metal is bound to the meat. For example, a piece of tuna will have the same amount of mercury whether it is eaten raw as sushi or cooked on the grill. People concerned about exposure to mercury because of the fish they eat should consult a doctor.

Why is there so much mercury in fish?

The methylmercury is absorbed by the bigger animal, and — since the bigger the fish, the longer it lives and the more it eats — larger fish species accumulate a lot more methylmercury in their body. In other words, fish higher up the food chain “bioaccumulate” more methylmercury than do those lower on the food chain.
