The Kansas health department has confirmed one positive case of norovirus related to Buffalo Wild Wings Inc, the department’s Johnson County office said.
Shares of the popular chicken wings chain fell as much as 13 percent to a 15-month low of $134.95 on Friday.
“These types of illness are common this time of year,” Johnson County Department of Health and Environment Director Lougene Marsh said in a statement. (bit.ly/1PZUvO0v)
The investigation is related to a gastrointestinal illness that affected at least 10 people who ate at a Buffalo Wild Wings restaurant in Overland Park in suburban Kansas City.
“Additional results are pending lab confirmation,” the department said. “There have been no further reports of illness.”
Buffalo Wild Wings was not immediately available for comment.
Last year, two norovirus outbreaks were reported at the Massachusetts and California outlets of popular burrito chain operator Chipotle Mexican Grill Inc.
Norovirus is the most common cause of food-borne disease outbreaks in the United States, with 19 million to 21 million cases and 570-800 deaths annually, according to the U.S. Centers for Disease Control and Prevention.
Infection usually occurs in places such as hospitals, cruise ships and universities, where people eat and live in close quarters.
