(CBS/AP) After consuming raw milk from the same dairy in Chambersburg, Pennsylvania, 35 people have been struck with illness, health officials say.
The confirmed cases of campylobacter bacterial infection include 28 people in Pennsylvania, four in Maryland, two in West Virginia, and one in New Jersey.
Health officials said Thursday consumers should discard raw milk bought from the Family Cow farm in Chambersburg on or after Jan. 1. The farm has voluntarily suspended raw milk production.
An Agriculture Department spokeswoman said final test results of milk samples from the farm may be available Friday.
The Food and Drug Administration warns that raw, or unpasteurized, milk can contain harmful bacteria. Dairy farmers say demand is growing because of concerns about hormones in traditional dairy products.
The FDA has more on the "dangers of raw milk."
