A federal judge has ordered a Delaware cheese company that was the source of a listeria outbreak in 2014 to pay a $100,000 fine.
The judge issued the sentence Thursday after Roos Foods Inc. pleaded guilty in January to a misdemeanor criminal charge. The company also agreed to a permanent injunction prohibiting it from distributing any food products unless it proves compliance with federal food safety laws.
Court records show that federal investigators found significant sanitation problems at Roos Foods after a listeria outbreak killed one person in California and sickened seven others in the Maryland suburbs of Washington.
The Kenton-based company ceased operations in 2014 after the Food and Drug Administration suspended its food facility registration. It has not reopened.
