Customers of the Family Cow dairy in Chambersburg, Penn., are once again being warned that the milk may be contaminated with Campylobacter, a harmful bacteria commonly found in cow feces. At least two people have fallen ill after drinking raw milk from the dairy, which has a history of foodborne illness outbreaks. Investigators from the Pennsylvania Department of Agriculture collected samples from the dairy on July 29, which have tested positive for Campylobacter. The dairy has been asked to discontinue selling milk until further notice. This is the third Campylobacter outbreak tied to raw milk from the Family Cow dairy in recent years. The first sickened at least 80 individuals between January and February 2012, while another five customers fell ill with infections in May 2013. Symptoms of Campylobacter infection include diarrhea, nausea, fever and abdominal cramping, which last anywhere from 2 to 10 days.
