DNA Tests Uncover Fish Restaurant Fraud

Something is fishy in American fish restaurants. Restaurant patrons spend big bucks on sushi, tuna steaks and halibut. DNA tests of fish samples from 700 restaurants in 21 states showed that 33 percent sold mislabeled products. Seventy-four percent of fish tested at sushi bars were frauds. Ninety-four percent of fish labeled white tuna was actually escolar, a cheaper fish that sometimes contains dangerous toxins. Only seven of 120 samples of red snapper were legitimate. Scientists from the environmental group Oceana conducted the study. About 90 percent of fish in the United States comes from foreign sources, and few people can tell the difference between the many varieties of white fish. (Oceana.org, 2016)
