People for the Ethical Treatment of Animals have released video footage depicting animal abuse by workers at a farm that supplies Hormel Foods.

Representatives from PETA worked undercover at the farm in Iowa for more than three months. Footage shot includes workers hitting sows with metal roads and slamming piglets on a concrete floor.
 
PETA wants to use the results of the investigation to pressure Hormel to demand that its suppliers ensure humane treatment of pigs.
