People who bought raw milk from The Family Cow farm in Franklin County this year should toss it, the state Department of Health said today.

Six people who drank the farm's raw milk, sold in stores in Pittsburgh and other parts of Pennsylvania, have contracted an infection from Campylobacter that can cause intestinal distress and can sometimes spread to the bloodstream and affect other organs, the department said. People who digest the bacteria usually notice symptoms within two to five days.

The raw, or unpasteurized, milk was sold with The Family Cow label and was clearly labeled "raw milk," the department said. The farm has temporarily stopped selling the raw milk while the Department of Agriculture awaits test results from milk samples.
