A trial date has been set for a Gibbon area farmer accused of selling raw milk and other unpasteurized dairy products, as well as uninspected meat. 59-year-old Michael O. Hartmann was in Sibley County Court on Friday after being charged with a total of 9 counts alleging that he sold raw milk and other products contaminated with E. coli and other pathogens, and then continued to sell the products despite a state embargo being instituted on his farm in 2010. Hartmann’s wife Diane, as well as his brother Roger, and alleged business associate Linda Schultz have also been charged. Diane Hartmann failed to appear in court on Friday, and a warrant was issued for her arrest. Warrants for Roger Hartmann and Linda Schultz were issued by the court in May. Michael Hartmann’s trial is now set to begin on August 28th. He faces up to a year in jail.
