DNA testing found that one-third (33%) of the 1,215 samples analysed nationwide (US) were mislabeled, according to US Food and Drug Administration (FDA) guidelines.
Of the most commonly collected fish types, samples sold as snapper and tuna had the highest mislabeling rates (87 and 59%, respectively), with the majority of the samples identified by DNA analysis as something other than what was found on the label. In fact, only seven of the 120 samples of red snapper purchased in the US were actually red snapper. The other 113 samples were another fish.
The findings demonstrate that a comprehensive and transparent traceability system – one that tracks fish from boat to plate – must be established at the national level. At the same time, increased inspection and testing of seafood, specifically for mislabelling, and stronger federal and state enforcement of existing laws combatting fraud are needed to reverse these disturbing trends, the company said.
