"If you order tuna at a D.C. restaurant, chances are half the time you’ll be getting another, less expensive fish in its place. But those odds are better than if you had wanted snapper. Testers nationwide found that 87 percent of the time, restaurants and grocery stores were selling something else under that label."
"As much as one-third of seafood sold in restaurants and groceries is fraudulently labeled, according to a report the advocacy group Oceana released Thursday. The group sampled 674 retail outlets in the District and 20 states between 2010 and 2012, often finding cheaper, farmed fish being sold in place of wild-caught ones.
Ninety-five percent of the sushi restaurants, 52 percent of other restaurants and 27 percent of grocery stores surveyed sold mislabeled seafood. While academics, consumer groups and media outlets in the United States and elsewhere have scrutinized fish labeling before and found major errors, Oceana’s effort is one of the largest seafood investigations to date."
