The Westchester County Department of Health is offering free post-exposure treatment for hepatitis A for any customers of the Dunkin Donuts/Baskin Robbins at 422 Washington Street in Peekskill who consumed drinks containing ice between April 1 and April 6.
Those costumers may have been exposed to hepatitis A by an infected employee.
The health department has already begun providing treatment to household contacts and coworkers. The employee is recovering and is not considered infectious after April 6.
Preventative treatment is only effective if given within two weeks of potential exposure. Anyone who drank beverages with ice between March 28 and March 31 may have also been exposed, but would not benefit from the treatment, health officials said.
