Ingham County Health Officer Linda S. Vail said as of 11:25 a.m. they have more than 240 reported cases.

Originally, the health department isolated the time period from Feb. 18 to Feb. 20 for investigation. Now they are looking at a much larger period from Feb. 16 to Feb. 21 to scope out all affected parties.

The cause still remains unknown, but the health department is hoping to know soon. Samples will be looked at by the Michigan Department of Health and Human Services.

The health department also requests that anybody who visited the Kellogg Center during the investigation period take a quick survey. The link can also be found on the health department's website. If for some reason it cannot be taken online, individuals with feedback can call (517) 887-4312 and leave a message.

"We need both those who experience no symptoms and those who were ill, most especially, to tell us about their recent visit," Ingham County Health Officer Linda S. Vail said in the press release.

Besides the current investigation period, there are no other reported cases. The Kellogg Center and State Room restaurant both went through thorough cleanups after initial reports trickled in. Both are still open today.

The Kellogg Hotel & Conference Center’s kitchens and the State Room Restaurant opened today after being closed due to precautionary reasons regarding confirmed cases of stomach illness.

According to a press release, individuals who visited the Kellogg Center from Feb. 18 to Feb. 20. were affected. As of Wednesday, county health officials confirmed more than 60 cases of stomach illness.

MSU spokesperson Jason Cody said in a press release MSU originally contacted the Ingham County Health Department after individual health illnesses were reported. University officials contacted the health department and are assisting them through a variety of means.

The cause of the illnesses have not been determined. Affected individuals showed signs of “becoming ill with gastrointestinal symptoms that last two to three days,” Cody said.

Some of the precautions taken were to close the Kellogg Center’s kitchen. The kitchen was then thoroughly cleaned while public areas at the center were also tended to through sanitation means.

While there were no incidents or issues regarding the State Room restaurant, it was also closed.

The incidents surrounding the Kellogg Center should not affect other dining halls and restaurants on campus. The closings were merely out of a sense of precaution due to reported incidents to the university.

“All regular food service has been restored, and the State Room is reopened,” Cody said.

Kellogg Center Officials contacted for comment all cited the press release for information.
