Adeel Ayub, 60, apologized for his actions in the videos, which were taken before he left the company in 2006, after supermarket chain Asda said it was investigating his actions at the Preston, England, store, the Lancaster Evening Post reported Monday.
The videos include footage of Ayub licking raw chickens that were returned to shelves, urinating into a trash bin, destroying awards earned by the store, slashing coworkers' clothing and setting off fire extinguishers.
"I know there is no excuse for my atrocious behavior and I am truly sorry for what I did back then. I express my profound apologies to Asda and to its staff and customers," Ayub said.
Police said they are reviewing CCTV footage from the Asda store.
