State officials in Idaho investigated an outbreak of Campylobacter infections linked to raw, unpasteurized milk.

The Idaho Department of Health and Welfare reported that 60 patients were identified with at least 45 of them specifically testing positive for campylobacteriosis. All 60 of the patients consumed raw milk before becoming sick.

The health department identified two dairies as sources of the implicated unpasteurized milk, but did named them. One of them is in northern Idaho and other one is in southern Idaho.

The first sick person was identified on May 19.

The investigation included testing of milk samples. Both milking operations worked in collaboration with the state health department and local public health agencies to identify and fix any potential sources of contamination.

The Idaho Division of Public Health collaborated with Panhandle District Health, Southwest District Health, Central District Health, Southeastern Idaho Public Health, South Central Public Health, and Eastern Idaho Public Health on the investigation.
