Food experts surprised at lack of concern over mislabelled fish in Canada

While controversy over horsemeat in the European beef and pork supply has captivated people around the world, food experts say Canadian consumers are blasé about mislabelled seafood in North America.

DNA analysis shows 33 per cent of fish sold in grocery stores, restaurants and sushi venues in the U.S. is mislabelled, according to a recent study conducted at the Biodiversity Institute of Ontario (BIO) at the University of Guelph.

The result is consistent with a 2011 study by BIO that looked at samples from five Canadian cities, including Vancouver, Toronto, Gatineau, Que., Montreal and Quebec City and found that 41 per cent of fish was mislabelled.
