Foster Farms was also looking into the incident, said Tim Walsh, a spokesman for the poultry processing company. DELHI, Calif. – A Foster Farms mill supervisor died of injuries suffered when he was buried under five feet of animal feed, the company said Saturday. Kevin Southerland, 51, was trying to remove corn stuck on the wall of a 150-foot-tall silo at the Foster Farms feed mill in Delhi on Wednesday when the feed fell on him. Police officers dug an unconscious Southerland out with their bare hands. He died Friday night at a local hospital, Foster Farms said. “Our thoughts and prayers are with Mr. Southerland’s family at this time,” said Foster Farms CEO Ron Foster. “Mr. Southerland was well regarded by all who knew him, and we will miss him.” 160Want local news?Sign up for the Localist and stay informed Something went wrong.
