One in five fish sold in America may be mislabeled, according to a report Thursday by an NGO that tested samples from several hundred markets and restaurants and alleged fraud runs through the entire fisheries supply chain.
The NGO Oceana said it analysed the DNA of 449 fish purchased from March to August 2018 in half of the US states and found that 94 were incorrectly labelled. That comes out to 21 per cent.
Oceana said it looked at species which for the past year have not been covered by a limited tracing programme implemented by US authorities. The tracing programme covers species such as salmon, cod, blue crab and grouper, which a previous Oceana study had shown were also subject to a high level of mislabeling.
The study said that the more expensive the fish, the more often it is labelled incorrectly.
