An undercover investigation at Colorado pig farm belonging to a major supplier of pork to Walmart allegedly reveals disturbing treatment of pigs in the company's supply chain, as well as the use of gestation crates, cages that keep pregnant sows from turning around or lying down. Along with eight other U.S. states, Colorado has passed laws to ban these crates - but the laws don't go into effect until 2018.
Actor Joaquin Phoenix introduced the footage, which was shot at a Seaboard Foods, the nation's third-largest pork producer and a supplier to Walmart. Shot by the animal welfare organization Mercy for Animals, the footage shows piglets being castrated and their tails taken off with shears, as well as pregnant animals living in cramped metal cages.
