The incident also prompted a statement from Catelli Duo, a restaurant in the Voorhees Town Center. The eatery's menu notes "Catelli Brothers veal" is included in its "signature house meatball."
"Catelli Bros. and Catelli Duo are two separate companies," it said. "The restaurant sources their meats from a number of suppliers and would never condone the inhumane treatment of animals."
It isn't clear how the Humane Society obtained the footage at the Shrewsbury plant. The group said it sent an investigator into Catelli Bros. at random last year.
The video, posted Monday on YouTube, shows still-conscious calves hanging upside down on a conveyor belt, and a calf being prodded while struggling to walk. The Humane Society said those actions violated a law that requires the slaughtering industry to use methods that prevent needless suffering.
The Department of Agriculture didn't respond to a request for comment. But a letter obtained by the Asbury Park Press said the agency's Food Safety and Inspection Service initiated the action after it determined that the business failed to handle animals humanely.
