The Chipotle restaurant across from Kent State University in Ohio appears to be the source of hundreds of norovirus illnesses this weekend.

One report cited Kent health officials as saying that 432 people had reported norovirus symptoms as of Monday afternoon.

Victims began showing up at local hospitals Thursday evening and the restaurant closed Friday.

Many of those who got ill were Kent State University students. The restaurant is directly across from the campus, and students who took part in a recent American Red Cross blood drive received a coupon for free food at Chipotle.

Kent Health Commissioner John Ferlito said Saturday the health department and the Denver-based restaurant chain agreed to switch employees out of concern that the outbreak might be caused by a sick employee. Several of the restaurant’s employees had been ill, but they also had eaten the restaurant’s food.

Chipotle spokesman Chris Arnold said in a statement Saturday,

"Local health department officials have found no violations in inspections of our Kent State restaurant conducted after this incident was first reported, and again in an inspection this morning. We have reopened our restaurant with their full support. We have taken preventative steps that meet or exceed health department requirements, and will continue to assist them in their investigation."

If someone wants to check out Kent State University and Chipotle on Facebook, I bet there’s lots of stories to hear.

Antibiotics? How about norovirus?
