Oceana, an international ocean advocacy group with an office in Toronto, Canada,  recently released a report that tested for seafood fraud in five Canadian cities. Seafood fraud can adversely affect human health, economies, human rights, and ocean ecosystems.  Of the 382 fish samples collected from 177 retailers and restautrants, 44% of samples were mislabelled and 100% of ‘snapper’ were mislabelled. 

Dr. Robert Hanner, Associate Professor at the University of Guelph played a key role in the study by having his commercial lab, TRU-ID, carry out DNA barocoding tests to verify the species of fish sampled.
