The New York Attorney General's Office has just published a report of a survey into the labelling of fish species in New York's supermarket chains. Fish (snapper, grouper, cod, wild salmon, halibut, sole, striped bass and white tuna) was sampled from 155 retail locations from 29 supermarket chains, and sent to Northeastern University for DNA testing. 27% of the samples were found to be mislabelled. A group of 5 of the supermarket chains were responsible for most of the mislabelled samples with more than 50% of their samples mislabelled. 87.5% of the lemon sole, and 67% of the red snapper were mislabelled, and 28% of the salmon was wrongly sold as wild when it was farmed. The report gives best practice for businesses to ensure that the consumer is not purchasing mislabelled fish.
