People are being warned by the state health officials who drink raw milk from a southwest Minnesota farm. The raw milk produced by Michael Hartmann is linked to illness in four Minnesotans, including a toddler.

His dairy is just outside this town of 800 people. He had a license to sell Grade A milk in 2001. Hartmann Dairy Farm, also known as M.O.M.'s, has had issues, from the State Agriculture Department. He declined to tell a judge his name in court and asserted he is a "natural man" with a constitutional right to raise and sell food without the interference of the Government.

Dr. Kirk Smith, Supervisor of state Health Department foodborne disease investigations revealed that it usually takes up to two weeks for cases to surface. The raw milk is not pasteurized, so according to health experts, it’s risky, but raw milk advocates believe it offers health benefits.

Michael Schommer, a spokesperson for the Minnesota Department of Agriculture said, “We're looking into the situation to see what kind of system was set up there and what could have contributed to the contamination”.

Samples of products from the farm have been taken from the state inspectors, which are being analyzed at a lab foe contamination.
