The Humane Society of the United States (HSUS) has released a new undercover video, taken at Oklahoma pig breeding facilities owned by two leading U.S. pork producers.

One of the facilities is owned by Seaboard Foods, the nation’s third-largest pork producer and a supplier to Walmart.

The video (WARNING: Very Graphic Content) shows animals suffering inside cramped gestation crates and, in some cases, at the hands of abusive employees.

“The pork industry’s notorious disregard for animal welfare is perhaps greater than in any other sector of the meat industry,” said Paul Shapiro, HSUS senior director of farm animal protection. “Permanently cramming pigs into cages so small they can barely move is simply out of step with mainstream American values about the proper treatment of animals.”

The HSUS has filed legal complaints with the U.S. Securities and Exchange and Federal Trade Commission alleging false and misleading statements about animal care by Seaboard Foods.
