Asian slave labor producing prawns for supermarkets in US, UK

Slaves forced to work for no pay for years at a time under threat of extreme violence are being used in Asia in the production of seafood sold by major US, British and other European retailers, the Guardian can reveal.

A six-month investigation has established that large numbers of men bought and sold like animals and held against their will on fishing boats off Thailand are integral to the production of prawns (commonly called shrimp in the US) sold in leading supermarkets around the world, including the top four global retailers: Walmart, Carrefour, Costco and Tesco.

The investigation found that the world's largest prawn farmer, the Thailand-based Charoen Pokphand (CP) Foods, buys fishmeal, which it feeds to its farmed prawns, from some suppliers that own, operate or buy from fishing boats manned with slaves.

As officials try to raise awareness about the existence of people who have been trafficked, a Seattle woman tells her unusual story. Her mother’s family was victimized by her father, a Ph.D. and concert violinist who worked with the U.N.
