INDIANAPOLIS (AP) — Indiana and federal health agencies are alerting consumers to a disease outbreak associated with drinking raw milk from a northern Indiana dairy.

At least 12 confirmed illnesses traced to campylobacteriosis (kamp-ih-low-BAK'-ter-EE'-oh-sis) are reported in Michigan and three in Indiana. The bacteria can cause diarrhea, cramping, abdominal pain, and fever.

The raw milk originated from Forest Grove Dairy in Middlebury. State health officials ask Indiana residents who might have milk from the dairy to submit it for free testing by calling (317) 233-7360.

Epidemiologist Pam Pontones of the Indiana State Department of Health says people should not consume any raw or unpasteurized milk products because they can may contain a wide variety of harmful bacteria that can cause illness and even death.
