I Am Sickened': Alleged Undercover Video of Wyo. Pig Farm Produces Shocking Animal Cruelty Images

Yet another shocking video showing the poor treatment of animals on a U.S. farm has been released by an animal rights advocacy group. Hiring an undercover investigator to examine the Wyoming Premium Farms facility in Wheatland, Wyo., the Humane Society of the United States pulled together a video that shows hogs being beaten, piglets being swung by their legs and injured animals neglected, among other horrors.

According to the HSUS statement, at one point a worker sat and bounced on the back of a sow with a broken hind leg as it squealed in pain.

"I am sickened and outraged by what I've seen, and any right-thinking person will have the same reaction," Wayne Pacelle, president and CEO of The HSUS, said in a statement. "The shocking abuse at this facility shows why so many Americans are calling for reforms in the pork industry."

Watch the four-minute video inside the farm (Content Warning: Graphic and cruel treatment of animals shown and some strong language):

The video states the farm is a supplier to Tyson Foods, but the Huffington Post received a response from the company denying this claim (but then clarified one of its subsidiaries has purchased pigs from the farm):

Tyson Foods spokesman Worth Sparkman emailed a statement to HuffPost, saying the company was "appalled" by the video and denying any connection between the Wyoming farm and the pork processed by Tyson. "Tyson Foods does not buy any of the hogs raised on this farm for our pork processing plants. We do have a small, but separate hog buying business that buys aged sows; however, these animals are subsequently sold to other companies and are not used in Tyson’s pork processing business," the statement said.

Sparkman clarified in a follow-up email: "A company that we own has purchased hogs from the farm. We will not purchase from this farm until we've had a chance to investigate."

The Huffington Post goes on to note that Tyson requires all suppliers to be certified through the Pork Quality Assurance Plus program, but HSUS only last month filed a complaint with the Federal Trade Commission that the program makes false claims of quality assurance. Here's what the National Pork Producers Council had to say about the complaint:

"The FTC complaint is the latest attack by animal-rights activists on America's hog farmers, an assault that seems obviously in response to the U.S. pork industry's strident opposition to congressional legislation that would allow federal bureaucrats to tell farmers how to raise and care for their animals."

The NPPC has also issued a statement about HSUS's recent undercover video of the Wyoming farm:

 Providing humane and compassionate care for their pigs at every stage of life is one of the ethical principles to which U.S. pork producers adhere. U.S. pork producers are committed to caring for animals in a way that protects their well-being. Just as it is to others, mistreatment of animals is appalling to pork producers. We do not defend and will not accept mistreatment of animals.

NPPC understands that the farm in question is taking immediate steps to address the situation, including an unannounced inspection of the facility by the farm’s consulting veterinarian. Individuals responsible for willful abuse of animals must be held accountable.

The Huffington Post reported the farm in question was a breeding farm with 5,000 sows and even touted providing a "clean" environment to rear the pigs. The Wyoming Premium Farms website appears to have since been taken offline or is temporarily down.

Last June, the Blaze reported a similar case of animal cruelty revealed in an undercover video of a pig farm in Iowa. The Huffington Post notes that as of March 2012, Iowa has made it illegal to access a farm "under false pretenses," meaning tactics for obtaining revealing videos such as this will be harder to come by in the state.
