The mercury problem isn’t contained to New York City’s sushi restaurants and markets

In case you needed another reason not to consume the dangerously overfished bluefin tuna: This week, The New York Times had a story about a study of mercury contamination, conducted by the newspaper, of leading sushi restaurants in New York. Guess which species showed the highest level of mercury? In the study, the Times collected samples of tuna sushi from leading restaurants like Blue Ribbon Sushi and Nobu Next Door. The results "found so much mercury in tuna sushi from 20 Manhattan stores and restaurants that at most of them, a regular diet of six pieces a week would exceed the levels considered acceptable by the Environmental Protection Agency."

In addition, the Times noted that "sushi from 5 of the 20 places had mercury levels so high that the Food and Drug Administration could take legal action to remove the fish from the market." In a sidebar about the health risks related to mercury, the Times noted that "several studies have concluded that elevated mercury levels may be associated not only with neurological problems but with cardiovascular disease among adults as well."
