Massachusetts: Boston health officials are investigating a possible case of Hepatitis A at a Tasty Burger in Boston. The restaurant, located on Nashua Street near North Station, remained open and served customers Friday. Citing privacy concerns, the Boston Public Health Commission did not release information about the worker’s role, but said: “At this time, based on inspection of the property and other information about the individual’s job responsibilities, we believe that the risk to the public is very low. We are not aware of any other cases linked to Tasty Burger.”

Florida: The Florida Department of Health said it notified Cooper’s Hawk Winery and Restaurant in Palm Beach Gardens on May 21 that one of its employees tested positive for hepatitis A. Two days later, an alert was sent to customers.
