The vast majority of the trace amounts of methylmercury in ocean-going fish is from natural phenomena such as underwater volcanoes. There has never been a single case of mercury poisoning in the United States due to the normal consumption of seafood.

Got Mercurys warning messages along with frightening but false claims from other activist groups are a large part of the reason why the North American diet contains the second-lowest percentage of fish in the world (7.0%) even though the dietary law of the land, the 2010 USDA Dietary Guidelines for Americans, recommends that 20% of the protein we eat should be seafood.

Seafood deficiency is the real grave health concern, not mercury, according to scientists and doctors. In fact, a 2009 study published in the Public Library of Science found that that some 84,000 cardiac-related deaths could be prevented each year if only people ate the amounts of seafood recomended by government and medical guidelines. Other research from the Institutes of Medicine, Harvard School of Public Health and the FAO/WHO say the benefits of seafood (eye health, brain health, heart health) far outweigh the risk from the trace amounts of methylmercury found in all ocean-caught commercial seafood.
