A salmonella outbreak linked to Sheetz convenience stores in Pennsylvania may have crossed the line into Ohio reports Beacon Journal medical writer Tracy Wheeler.

The Ohio Department of Health is reporting thirteen laboratory-confirmed cases of salmonella in people who had eaten at Sheetz. However, as of Tuesday afternoon, just two of those thirteen cases were confirmed to be the same bacterial strain, known as javiana, that’s being investigated in Pennsylvania.

Three of Ohio’s cases are in Summit County and four are in Stark. There are two cases in Mahoning County and one each in Medina, Cuyahoga, Lorain and Tuscarawas counties.

Pennsylvania health officials said Monday that 110 people were sickened in that state after eating at Sheetz. The Food and Drug Administration reported additional illnesses in Maryland and West Virginia.
