The owner of the Pennsylvania dairy, Your Family Cow farm in Chambersburg, posted a message on the farm's website last week saying that several customers had called them to say they had been experiencing "acute diarrhea, fever and stomach cramps."
Owner Edwin Shank said in the posting that the farm's testing had shown samples to be negative for campylobacter and speculated that the illnesses may be from another cause. But the Pennsylvania health department has linked the outbreak to the farm, and a spokeswoman for the Maryland's health department says an unopened bottle from the farm tested positive for campylobacter.
Raw milk sales are illegal in Maryland, but the state has four illnesses from the outbreak. Those sickened presumably drove to Pennsylvania and brought the milk back for their own consumption, said Maria Said of the Maryland Department of Health and Mental Hygiene.
One person is also sick in New Jersey and two in West Virginia, according to the Pennsylvania Department of Health. Thirty one people are sick in Pennsylvania, many of them in Franklin County, where the farm is located.
Pennsylvania has had at least seven disease outbreaks linked to raw milk consumption since 2006, involving almost 200 people, according to the health department. Pennsylvania is one of 17 states where some type of raw milk sales are allowed, according to the National Association of State Departments of Agriculture.
