The search is widening for people who may have been contaminated by hepatitis A at a Cortlandt Manor restaurant.

County health officials say even more people may have been exposed to the virus than originally thought at the Monteverde at Oldstone restaurant.

The Westchester County Health Department was alerted by the state after a bartender's lab results showed he had hepatitis A and that he worked at a restaurant. Authorities say the bartender had been serving drinks and was unaware he was ill, and possibly exposed customers or other employees.

Authorities started looking for anyone who had drinks at the restaurant from the end of May to the beginning of June to see if they were exposed. Westchester County Executive Rob Astorino says over 100 people have been treated already.

However, Astorino says that they recently discovered that the bartender served drinks at a wedding two weeks ago and people from outside the county may have been exposed.

“So we are trying to reach out to these people and their health departments so that we don’t have any infectious outbreak in some way,” says Astorino. 

Restaurant management told News 12 that the bartender did not “work” the wedding, but some members of the bridal party did purchase drinks from him.

Health officials say hepatitis A is a viral infection that affects the liver, making a person fatigued, experience abdominal pains and causing loss of appetite.

People who have been at the restaurant are urged to call Westchester County Health Department in White Plains at 914-813-5000.

The restaurant has been inspected and is open for business.

The Westchester County Health Department has announced another day of testing that will take place Tuesday at their office in White Plains.
