A Bloomington McDonald’s restaurant is closed while the McLean County Health Department and Illinois Department of Public Health investigate a suspected case of salmonella at the restaurant.

Health department communications director Kera Simon said owners Bob and Julie Dobski voluntarily closed the restaurant at 2410 S. Main St. Wednesday night for the Thanksgiving holiday and chose not to reopen.

The confirmed cases range from Oct. 18 to Nov. 11, said Simon, and were most likely a result of human transmission and not a specific food.

“All of the employees are being tested and the restaurant will not reopen until they have enough staff who have been confirmed they are safe to serve,” said Simon, adding, “We are still early in the investigation. It was a low number of cases, less than 10, and it was a mild strain of salmonella.”
