The Family Cow dairy in Chambersburg began bottling again Tuesday. The dairy had been shut down since illnesses were first reported late last month.
Officials say confirmed cases of Campylobacter infection include 36 people in Pennsylvania, four in Maryland, two in West Virginia, and one in New Jersey.
The Pennsylvania Department of Agriculture cleared the dairy to resume production on Monday after series of inspections.
Farm owner Edwin Shank says he's installing lab equipment to test for E. coli every time the dairy bottles raw milk.
Shank says he's hurt by the illnesses suffered by his customers and wishes for their full recovery.
