There's something awfully fishy about your seafood dinner

According to researchers who surveyed 60 businesses in South Florida, there’s almost a one-in-three chance that the fish you order at a restaurant is not the fish served on your plate. The findings from Oceana, an ocean conservation organization, found mercury-laden king mackerel being sold as grouper, and that six out of seven red snapper samples from restaurants and markets were not red snapper at all. Tuna was not, in fact, tuna 100 percent of the time at the sushi outlets investigated, with the common substitute being escolar. As bad as this is (escolar, or snake mackerel, can cause “severe gastrointestinal problems”), the rate of fish fraud in South Florida was actually 20 percent less than in Boston and Los Angeles. [Source]
