High Mercury Levels Found in Tuna Sushi

A quarter of tuna sushi sampled in New York contained mercury levels so high that the FDA could take legal action to ban the fish from the market, reports the New York Times.  Although the sushi was collected in New York City, experts believe samples elsewhere would be similar. “No one should eat a meal of tuna” more than once about every three weeks, said the professor who analyzed the samples.

Mercury has attracted attention over the last few years after the FDA warned pregnant women and small children not to eat too much mercury-bearing fish. Ongoing studies are underway, but no agency currently tests food products for mercury levels. “Maybe we won’t sell tuna sushi for a while, until we get to the bottom of this,” said one shopowner.
