HARRISBURG, Pa. (AP) -- Health officials now say 12 people in Pennsylvania and Maryland who consumed raw milk from the same farm have been stricken with illnesses that suggest the product may contain harmful bacteria.

The Pennsylvania Department of Health said Monday it had confirmed six more cases in the three days since it said the Family Cow store in Chambersburg had voluntarily suspended production.

The department recommends that buyers discard any product purchased after Jan. 1. A message left at the farm wasn't returned Monday, although it says on its website that its raw milk is third-party tested.

Raw milk hasn't been pasteurized.

The farm says it sells raw milk at its farm store and at drop-offs, grocery stores and markets around Pittsburgh, Philadelphia, the Lehigh Valley and southcentral Pennsylvania.
