LINCOLN, Neb. (AP) — A Nebraska pig supplier is promising to investigate animal abuse allegations after an animal rights group released an undercover video showing pigs with open wounds and other health problems.

The Animal Legal Defense Fund released the footage Wednesday and sent a letter to the Nebraska and Illinois attorney general’s offices, requesting a criminal investigation. The facility is owned by The Maschhoffs, a pork producer based in Carlyle, Ill.

The company said in a statement Thursday it will take immediate action to address the allegations and will cooperate with any criminal investigation. Hormel Foods, one of its largest customers, says it has suspended all sow operations at the Nebraska plant and is sending auditors to see whether animal care requirements are being followed.
