Customers at a Dunkin’ Donuts in New Jersey may have been exposed to Hepatitis A after a worker at the shop tested positive for the communicable disease, a report said Friday — which happens to be National Doughnut Day.

The employee at the doughnut shop in Turnersville worked while potentially infectious from late May through early June, NBC Philadelphia reported, citing a statement from the Gloucester County Department of Health.

The health department’s release comes on the first Friday in June, which is National Doughnut Day.

Hepatitis A, which is preventable by vaccine, spreads through contaminated food and can cause nausea and abdominal pain.

The Gloucester Health Department added that customers who ate or drank at the outpost have a low risk of contracting the disease, but suggested people who are not vaccinated should receive “post-exposure prophylaxis,” or PEP, to fight infection.

“PEP consists of hepatitis A vaccine and/or immune globulin and can further reduce the risk of acquiring hepatitis A,” the health department said in the statement.

“To be effective, PEP should be received as soon as possible, but no later than June 15, 2019,” they added.

Dunkin’ Donuts said in a statement that they take the news “very seriously.”

“Upon learning of the diagnosis, our franchisee, who independently owns and operates the location, took immediate, proactive steps to work with the Gloucester County Health Department and to clean and disinfect the restaurant,” a spokesperson for the doughnut chain said.
