The U. S. Department of Agriculture has shut down a meat processing company in Chino, Calif. after evidence was released that showed how workers committed “egregious violations of humane handling regulations” against animals.

The Humane Society of the United States released a shocking video last week revealing how workers of the Westland Meat Co. tortured cows that were too injured or weak to stand up.

The footage was obtained by an employee of the Humane Society who worked undercover in the meat company for several weeks and recorded terrible acts of torment and torture committed on the animals.

The USDA promptly suspended business with the company last week, initiated an investigation at the plant and warned schools across the country to stop serving beef from the company to children.

Westland Meat Co. and sister company Hallmark Meat represent one of the largest suppliers of beef to the USDA, which distributes it to school lunch programs, the elderly and American Indians.

Officials said Tuesday the suspension would remain in place for the Westland Meat Company until “written corrective actions” are submitted that prove animals have been treated humanely, The Associated Press reports.

“On Feb. 4, the Food Safety and Inspection Service suspended inspection at Westland Meat Company based on the establishment's clear violation of federal regulations and the Humane Methods of Slaughter Act,” the USDA said in a written release late Tuesday. “This Notice of Suspension is a regulatory course of action available when FSIS finds egregious violations of humane handling regulations.”

The video caused controversy over the unfair and cruel treatment of animals as well as over the safety of products provided by the company. “Downer” cows, those that are not able to stand up, are more likely to produce beef contaminated with foodborne illnesses such as mad cow disease, E. coli and salmonella.

The USDA has so far said there is no indication any unsafe meat left the facility. “We maintain an inspection system that safeguards the safety and wholesomeness of our food supply. USDA will take appropriate action based on the findings of the investigation,” the statement added.
