The Westchester Health Department says some patrons of a New York doughnut shop may have been exposed to hepatitis A by an infected employee.

Hepatitis A, a liver infection, is rarely serious. But the county is offering free post-exposure treatment.

Acting Health Commissioner Dr. Cheryl Archbald says customers may have been exposed if they had any iced drinks between March 28 and April 6 at a combined Dunkin' Donuts and Baskin Robbins shop on Washington Street in Peekskill.

Department spokeswoman Caren Halbfinger said the employee may have reached into the ice machine with bare hands while he was infected.

Symptoms of hepatitis A can include fatigue, fever, poor appetite, abdominal pain, diarrhea, dark urine and yellowing of the skin and eyes.
