New undercover footage has prompted the firings of seven pig farm workers and raises questions about the ethics of Walmart's supply chain.
Warning: Video contains graphic content.
Mercy For Animals (MFA) released the undercover footage, taken at a Seaboard Foods in Colorado, on Wednesday. The video shows workers beating pigs in the face and body with heavy cans, and snaring a terrified pig and shooting him in full view of the other animals.
Investigators also witnessed pigs biting desperately at the bars of their pens, and packed into dirty pens so tightly they couldn't move.
"The industry wouldn't even defend the malicious hitting and punching of animals," Matt Rice, director of investigations for MFA, told The Dodo.
