Nonprofit ocean protection group Oceana took 1,215 samples of fish from across the United States and genetically tested them in order to bring us the following astonishing facts:

Sushi restaurants were far more likely to mislabel their fish than grocery stores or other restaurants.
In Chicago, Austin, New York, and Washington DC, every single sushi restaurant sampled sold mislabeled tuna.
84% of fish samples labeled “white tuna” were actually escolar, a fish that can cause prolonged, uncontrollable, oily anal leakage.
The only fish more likely to be misrepresented than tuna was snapper, which was mislabeled 87% of the time, and was in actuality any of six different species.
