An employee at a McDonaldâ€™s location in Waterloo, New York, was diagnosed with hepatitis A. Now the branchâ€™s owner, Jascor Inc., is being sued by a customer for potentially exposing peopleÂ to the virus, which causes liver infections.
Although McDonald's customer Christopher Welch hasnâ€™t fallen ill, heÂ filed a class-action status lawsuit on Nov. 18, which could impact more than 1,000 customers, Reuters and Eater reported.
On Nov. 13, the Seneca County Health Department confirmed that one of the employees had hepatitis A, though they added thatÂ there was a low risk of diners contracting the illness. Still, they advised customers who went to the WaterlooÂ McDonaldâ€™s restaurantÂ on Nov. 2, 3, 5, 6 and 8 to look at treatment if they havenâ€™t been vaccinated against hepatitis A.
Welch did consume food at the restaurant onÂ at least one of those days, and he hasÂ received a vaccination after eating there, Eater reported.
