Newly installed Agriculture Secretary Ed Schafer said the department was taking the allegations seriously after video footage showed workers at the Hallmark Meat Packing Co. repeatedly kicking cows and ramming them with the blades of a forklift as the animals squealed in pain.

Schafer said “appropriate actions will be taken” if violations are found in the facility but he said there was no evidence that the nation’s beef supply was at risk.

“There is no immediate health risk that we are aware of,” he said.

Hallmark, based in Chino, Calif., supplies the Westland Meat Co., which processes the carcasses. The facility is a major supplier to a USDA program that distributes beef to needy families, the elderly and to schools through the National School Lunch Program. Westland was named a USDA “supplier of the year” for 2004-2005 and has delivered beef to schools in 36 states.

The video, released Wednesday by The Humane Society of the United States after a six-week undercover investigation, also showed plant workers jabbing in the eyes and applying electrical shocks to the “downed” dairy cows — those who are too sick or injured to walk — in an effort to force them into the federally inspected slaughterhouse.

In one scene, the workers shoot high-intensity water sprays up the cows’ noses in what The Humane Society described as a form of animal “waterboarding,” or torture that simulates drowning.
