7 of the most faked seafoods in the world

Seafood is one of the most commonly fraudulent foods we come in contact with, according to the ocean-conservation nonprofit Oceana. Your red snapper could actually be a tilapia fillet. That wild-caught salmon? It could be farm-raised. Crab, lobster, and scallops have also been victims of fraudulent swaps — and some of the substitutions could be harmful to human health. But there are also entire criminal rings smuggling seafood across the world. They often fish illegally and have been involved in human trafficking. Why is it so hard to catch bad actors in seafood supply chains? And how can we make sure we're getting the seafood that's on the label?
