Even though the risk to people who ate or drank beverages at the Dunkin’ Donuts between those dates is low, health officials recommend people to receive a post-exposure prophylaxis out of an abundance of caution.

All of the store employees were identified and are able to return to work after receiving PEP. The Dunkin’ Donuts has been cleared to reopen.
