Campylobacter is a bacterial cause of diarrhea, nausea and vomiting, and can progress to more serious illness, such as a bloodstream infection and other complications. Illness generally occurs two to five days after exposure. In 2011, Maryland reported nearly 600 Campylobacter infections.
The implicated milk is labeled "raw milk" (meaning, not pasteurized) and is sold under "The Family Cow" label in plastic gallon, half gallon, quart and pint containers. The Family Cow dairy sells directly to consumers at its on-farm retail store and at multiple drop-off locations and retail stores in the following Pennsylvania counties: Bucks, Cumberland, Dauphin, Delaware, Franklin, Lebanon, Montgomery, Philadelphia and York counties.
Raw milk and products made from raw milk (including certain cheeses, ice cream, and yogurt) can pose severe health risks. Pasteurization is performed by briefly heating raw milk to kill disease-causing germs (e.g., Salmonella, Escherichia coli O157, Campylobacter) that can be found in raw milk. Maryland state law prohibits the sale of unpasteurized milk.
