Family Dollar, a subsidiary of Dollar Tree, has been fined nearly $42 million for selling products from a rodent-infested warehouse in Arkansas. The company pleaded guilty to food and drug adulteration charges after a federal inspection found living, dead, and decaying rodents at the distribution center. The fine is the largest-ever monetary criminal penalty in a food safety case in U.S. history. Family Dollar knew about the rat infestation at its now-closed facility since January 2020 and will be under strict corporate reporting requirements for the next three years.
