“The Humane Society of the United States said yesterday that an undercover worker at a farm owned by the world’s largest pork producer saw breeding pigs abused and crammed into small gestation crates. The animal welfare organization released the results of a month-long undercover investigation at a Waverly, Va., factory farm owned by Murphy-Brown, a subsidiary of Smithfield Foods Inc. Murphy-Brown is Smithfield’s livestock production subsidiary and is the world’s largest producer of pigs for slaughter. The Humane Society called on Smithfield to renew its commitment to phasing out the crates.” (12/16/10)
