(CNN) Chipotle Mexican Grill has agreed to pay a record $25 million fine to resolve criminal charges involving food-safety violations, the Justice Department said.

The charges related to "adulterated food that sickened more than 1,100 people across the United States from 2015 to 2018," the department said in a release.

The fine is the largest "ever imposed in a food-safety case," the department said.

The restaurant chain also agreed to put in place a "comprehensive food safety compliance program," the department said.
