Last week, the Guardian reported that Thai exporter CP Foods purchases fish meal for its shrimp stock made with fish caught by human trafficking victims aboard Thai fishing vessels. The fishermen reported brutal physical violence, even murder, regularly occurring on boats. The report identified major retailers – including Walmart, Costco, Tesco and Carrefour –buying shrimp from CP Foods, a groundbreaking link between forced labor in the “trash fish” industry in Thailand and the seafood on menus and in grocery store freezers around the world.
