GIBBON, MINN. -- The organic farmer who produced raw milk linked to illness in four Minnesotans, including a toddler who remained hospitalized Thursday, has for years fought the government's efforts to regulate him.
Michael Hartmann, whose dairy is just outside this town of 800 people, last had a license to sell Grade A milk in 2001. He has kicked inspectors off his property, refused 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 government interference.
State officials said Thursday that the investigation of his dairy is continuing but said they have little doubt it produced the raw milk containing a deadly strain of E. coli.
"I am concerned that we are going to hear about more cases," said Dr. Kirk Smith, supervisor of state Health Department foodborne disease investigations. It often takes up to two weeks for cases to surface, he added.
While raw milk advocates believe it offers health benefits, experts say it's risky because it hasn't been pasteurized. The heat treatment discovered more than a century ago reduces bacteria, including E. coli O157:H7, which brings on diarrhea and sometimes more serious illness.
Three of the patients in the current outbreak have been released from the hospital, but the toddler developed a potentially deadly complication.
Hartmann declined to talk about the outbreak with a reporter Thursday, other than to say, "It's all been blown out of proportion."
Hartmann Dairy, run by Hartmann and his wife, Diane, has long operated as an organic farm, and in the early 1990s sold pasteurized organic milk to grocers and several Twin Cities co-ops under the Minnesota Organic Milk or "M.O.M.s" brand.
