A Detroit company that has supplied sandwiches to police departments, gas stations and small stores for more than 50 years has been ordered to stop until it complies with food safety rules.

A federal judge signed an injunction Thursday, weeks after ruling in favor of regulators and against Scotty’s Inc. The company was accused of violating safety rules, especially in its handling of tuna sandwiches. The customers are in Ohio and Michigan.

Inspectors found mold on ceiling tiles and a lack of appropriate hand-washing, among other problems. The government says Scotty’s didn’t have a food hazard analysis plan in place.

A message seeking comment from Scotty’s attorney Jerome Moore wasn’t immediately returned Friday.
