With more than 300 people now reporting symptoms consistent with norovirus linked to the Wild Chef Japenese Steakhouse in Michigan, public health types have now said it’s safe to reopen.

Ottawa County Public Health spokeswoman Kristina Wieghmink said the department is still awaiting laboratory results to determine what the cause of outbreak was. Results are expected in the next few days.

“Media coverage and public response has aided in data collection and has contributed greatly to the investigation of this event,” Wieghmink said.

Wild Chef met a series of requirements before it was allowed to reopen, including cleaning and disinfecting of all of its equipment, floors, walls and ceilings. It also has developed new written policies and procedures, and provided staff training on proper washing of hands, food preparation, use of gloves and reporting of illnesses, Wieghmink said.
