A recent campylobacteriosis outbreak in Pennsylvania demonstrates that observing or exceeding state safety regulations often isn’t enough for dairies to prevent Campylobacter jejuni from contaminating raw milk.
The outbreak was linked with raw milk from a dairy that was certified by the Pennsylvania Department of Health and conducted milk coliform and somatic cell testing more often than required. Despite its adherence with regulations, the dairy had been identified as the source of a 2012 campylobacteriosis outbreak that was the largest raw milk–associated outbreak in Pennsylvania in 2 decades, with 148 cases diagnosed.
