SLEEPY EYE  — A large hog producer based in southern Minnesota said it has suspended seven employees at its hog farming facilities after an animal welfare group made claims of abuse.

Christensen Farms, of Sleepy Eye, said it’s conducting an internal investigation into the claims of “possible improper animal care.”

The Los Angeles-based Last Chance for Animals plans to release a video today that the group said shows violations of Minnesota’s animal cruelty law. According to a press release, the video has been turned over to local law enforcement.

Christensen Farms operates more than 50 sow farms across the Midwest. The company said all employees are required to sign a document which details the company’s animal welfare policies.
