From PETA:
For more than three months, PETA went undercover at an Iowa pig factory farm, which supplies piglets who are raised and killed for Hormel products. PETA found rampant cruelty to animals - committed by workers and supervisors. The farm changed ownership and management during PETA’s investigation, but that made no difference to the animals who were born and confined there: Abuse and neglect were widespread during PETA’s entire investigation.
