A Cheektowaga pizzeria is responsible for at least four cases of hepatitis A, according to the Buffalo News.

The Buffalo News reports, "A cook employed at Doino's Pizzeria Bar & Grille at 2709 Harlem Road, Cheektowaga, tested positive for hepatitis A but did not initially tell the county Department of Health about his employment there."

County Executive Mark Poloncarz stated the county is "closely monitoring the situation."

Anyone who ate food from the restaurant between Aug. 20 and Sept. 3 could have been exposed to the hepatitis virus, reports the Buffalo News.
