The department issued a public health alert Friday about milk distributed through Family Farms Cooperative in Vandalia, Mich., the Detroit Free Press reports.
The illnesses reported in Wayne, Washtenaw and Macomb counties have been identified as campylobacter. The symptoms include high fever, abdominal cramps and nausea, and can last as long as two weeks.
The suspect milk comes from Indiana, the state said. 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."
