More than 120 Boston College students were taken ill after eating at the same Chipotle at 1924 Beacon Street in Brighton in December 2015.

After receiving reports of multiple cases of gastrointestinal illness among patrons who ate at the Chipotle Mexican Grill in Cleveland Circle, the Boston Public Health Commission, the City of Boston Inspectional Services Department, and the Massachusetts Department of Public Health launched an investigation to determine the cause and the nature of the illness. Laboratory testing confirmed the presence of norovirus.

There were 136 known cases of norovirus from people who ate at Chipotle; others who were contacts to these cases have also become ill.

City inspectors closed the Chipotle, located in Brighton near BC’s campus, “until further notice” after reporting three critical health violations following a visit Monday.

According to the Inspection Services Department, an employee came to work sick last Thursday and chicken and steak on the service line were being held at 128 degrees F and 124 degrees F, respectively—below the required temperature range of at least 140 degrees F. The third violation was of multiple reports of foodborne illness from the location. All three citations were given the department’s most serious grade of violation. A spokeswoman for the Boston Public Health Commission said the illnesses were likely caused by norovirus, but final test results are not expected to for a couple of days.
