In Pennsylvania, where a raw milk Campylobacter outbreak has sickened at least 77 people during the last month, dairies – even those selling raw milk, are only required to test for pathogens twice a year, according to Penn State Food Safety, a blog by the Penn State College of Agricultural Services.
Pasteurisation kills harmful pathogens, but raw milk is unpasteurized and can sicken consumers if tainted. Since 2006, there have been seven raw milk outbreaks involving five or more people, sickening 284 Pennsylvanians. In addition, there were nine clusters of five or fewer cases during that same period.
