In Idaho, 45 people have been confirmed to be infected with Campylobacter because they drank raw milk, with several others also sick.
Campy is a bacteria that causes diarrhea and stomach cramps, and in 1-5% of cases, can cause reactive arthritis that lasts for months.
The Department of Health and Welfare didn't disclose the names of dairies in North Idaho and southern Idaho that are linked to the outbreaks.
