FRESNO, Calif. (AP) — Federal officials say nothing they have seen so far in covert video shot in a California slaughterhouse shows meat from cows that may have been sick made it into the food supply.

But the federal government and McDonald’s Corp. have suspended purchases of meat from the facility.

The suspensions by the U.S. Department of Agriculture and the fast-food chain came after an animal welfare group’s video shot at a slaughterhouse operated by Central Valley Meat Co. showed cows that appeared to be sick or lame being beaten, kicked, shot and shocked in an attempt to get them to walk to slaughter.

“There are behaviors in the video which appear to be unacceptable and would not adhere to the standards we demand of our suppliers,” McDonald’s said in release.

The video was shot in June and July by an undercover operative for the group Compassion Over Killing who worked at the plant and also gave a written statement to the USDA about events not on tape.

“We do know that workers were trying to make non-ambulatory cows not eligible for slaughter go to slaughter,” said Erica Meier, executive director of the animal welfare organization. “We believe red flags are raised for sure with our video, but it’s up to the USDA to decide.”

It’s against the law to slaughter a nonambulatory animal for food out of concern that it could be infected with bovine spongiform encephalopathy, also known as mad cow disease.

The Hanford slaughterhouse is in the same city where a dairy cow at a rendering plant was discovered in April to have mad cow disease. The USDA said earlier this month it was an isolated case and didn’t pose a threat to the food supply.

Central Valley Meat Co. primarily slaughters dairy cows that have lost their value as milk producers.

The USDA bought 21 million pounds of beef from the company in 2011 for the national school lunch and other federal food programs.

Records show the government made five large-scale purchases of ground and chunk beef, spending more than $50 million of the total $135 million allocated by the government for such acquisitions that year.
