The next time you order tuna at a sushi restaurant - watch out! - it may not be what you think it is. A team of scientists from Columbia University and the American Museum of Natural History conducting a genetic research project found that more than half of tuna ordered from 31 restaurants were "misrepresented" or selling endangered southern bluefin tuna. Some samples were not tuna at all, but escolar, a fish with fatty flesh that could pass as tuna but can cause diarrhea when consumed. "A piece of tuna sushi has the potential to be an endangered species, a fraud or a health hazard," reports the authors. "All three of these cases were uncovered in this study."
