The Kansas health department is yet to find the cause and source of a gastrointestinal illness that affected at least 10 people who ate at a Buffalo Wild Wings Inc restaurant, a spokeswoman for the department’s Johnson County office said.
Shares of the popular chicken wings chain fell as much as 7.8 percent to a 15-month low of $138.31 on Wednesday.
The Johnson County Department of Health and Environment said on Tuesday that it was working with state health officials in probing reports of gastrointestinal illnesses that affected the people, who ate at a Buffalo Wild Wings outlet in Overland Park in suburban Kansas City.
Laboratory results are awaited, the department said, adding that there were currently no confirmed cases of norovirus.
