The FDA has released a statement that between March 24-26, 2010, they have received 12 reports of confirmed illnesses due to contaminated raw milk consumption.

They are working with the state health departments of Michigan, Illinois, and Indiana in their investigation.

The source of the contaminated milk was identified as Forest Grove Dairy in Middlebury, Indiana, whose milk was found to contained Campylobacter.

From the FDA press release:

Symptoms of illness caused by various bacteria commonly found in raw milk may include vomiting, diarrhea, abdominal pain, fever, headache and body ache. Most healthy individuals recover quickly from illness caused by raw milk. However, some people may have more severe illness, and the harmful bacteria in raw milk can be especially dangerous for pregnant women, the elderly, infants, young children and people with weakened immune systems.

If consumers of raw milk are experiencing one or more of these symptoms after consuming raw milk or food products made from raw milk, they should contact their health care provider immediately.
