The Guardian published a story about fraud going on in the seafood industry called “Seafood fraud happening on a vast global scale.” The full article can be linked to below.
“A Guardian Seascape analysis of 44 recent studies of more than 9,000 seafood samples from restaurants, fishmongers and supermarkets in more than 30 countries found that 36% were mis-labelled, exposing seafood fraud on a vast global scale. Many of the studies used relatively new DNA analysis techniques.
In one comparison of sales of fish labelled ‘snapper’ by fishmongers, supermarkets and restaurants in Canada, the US, the UK, Singapore, Australia and New Zealand, researchers found mis-labelling in about 40% of fish tested. The UK and Canada had the highest rates of mis-labelling in that study, at 55%, followed by the US at 38%.”
At 36%, more than one in three pieces of fish purchased is mis-identified either intentionally or accidentally. With so many fishes sold using geography as an adjective, the opportunity and necessity to mis-labelling are heightened. The other factors are over-fishing and global warming causing some species to go to colder waters.
Apparently, there is less Cod in Cape Cod these days, but plenty of Dogfish. For some reason, Americans do not like Dogfish, but based on the above, my guess is many are eating it without even knowing it. It is cheaper and available, so a cost conscious chef can do the math and substitute it.
So, be aware that the Chilean Sea Bass is most likely not such, no matter how much you paid for it. How about a nice piece of Flounder?
