NEW BRITAIN, Conn. (WTNH) — Central Connecticut State University is investigating after several students exhibited food poisoning symptoms on Wednesday.

The university subsequently closed the Hilltop Café, while officials investigated a possible food poisoning issue.

The Central Connecticut State University Environment Health and Safety Department is working alongside the City of New Britain Health Department and the food service provider Sodexo to investigate the possible food poisoning issue.

University officials provided an update on Thursday night and said no unique food item has been pinpointed as the source.

The City of New Britain Health Department will now expand its survey to determine the root cause of the student illness.

A university spokesperson said a group of symptomatic students are in the process of being contacted and tested. The results of the tests are not expected until next week.

Several protocols including the sanitization of high touch points which include doorknobs and bathroom sinks will be implemented out of an abundance of caution, while the investigation is underway.

The City of New Britain Health Department has approved all Central Connecticut State University food service establishments to be in operation.

According to Central Connecticut State University, students can get services for any symptoms including nausea and diarrhea at the Student Wellness Center for free.

To make an appointment, students can call (860) 832-1926.
