Today, PETA released undercover footage depicting cruelty to dairy cows inside a Land O’Lakes supplier facility in Pennsylvania. The photos and video reveal filthy living conditions, abuse, and animal welfare violations. Some cows are in such failing health that they collapse and are left for dead. PETA reports that Land O’Lakes inspected the farm in June 2009 and noted some concerns, but did not follow up with them. Video also caught farm personnel electro-shocking and kicking sickly cows, and even jabbing one cow with a pocketknife. Those employees have since been charged with animal cruelty. In a response posted Tuesday afternoon, Land O’Lakes announced that it’s investigating the claims.
