The number of people who became sick with an intestinal infection after drinking raw milk from a Franklin County farm continues to rise.

As of today, the Pennsylvania Department of Health said 78 cases of campylobacter bacteria are connected to unpasteurized milk sold in mid-January by The Family Cow dairy in Chambersburg.

The department says it is the largest foodborne outbreak related to raw milk in the state.

Of the cases, 68 people were sickened in Pennsylvania, five in Maryland, two in New Jersey and three in West Virginia. At least nine people were hospitalized, state Department of Health spokeswoman Holli Senior said.
