NGO Oceana released its nationwide survey of seafood labeling. Much of the seafood we consume is mis-labeled and of all the fish, 89% of fish sold as snapper was not. It could be tilapia. It could be another species of snapper. It could be rockfish.
Why does this matter? Because if you're trying to buy sustainable fishes, you need to have faith in what you're buying is labelled correctly.
My new motto is that 'it takes a PCR machine to know what fish you're eating'. Consumers beware!
