The state Department of Community Health says that a bacterial infection that has sickened at least eight people in southeast Michigan has been traced to raw milk.

The Detroit Free Press has reported that the department issued a public health alert Friday about milk distributed through Family Farms Cooperative in Vandalia, Mich.

It has been identified that the illnesses reported in Wayne, Washtenaw and Macomb counties is campylobacter. The symptoms include high fever, abdominal cramps and nausea, and can last as long as two weeks.

The state further said that the suspect milk comes from Indiana. It is sold in plastic containers with green and white caps and labels that read: "Forest Grove Dairy, Middlebury, Indiana; raw cow's milk, warning -- not pasteurized, 128 fl. oz." (With Inputs from Agencies)
