An investigation found “live rodents, dead and decaying rodents, rodent feces, urine and odors,” at a warehouse in Arkansas.

Family Dollar Stores was this week ordered to pay $41.6 million for using a rodent-infested warehouse to distribute food, cosmetics and medical devices to more than 400 stores across the South.

The largest criminal penalty of its kind comes after a U.S. Food and Drug Administration investigation found “live rodents, dead and decaying rodents, rodent feces, urine, and odors, and evidence of gnawing and nesting,” at the company’s distribution center in West Memphis, Arkansas, the Justice Department said in a statement.
