Wisconsin Farmer and 16 Cattle Die in Tragic Manure Tank Accident

Michael Biadasz, a 29-year-old farmer from Amherst, Wisconsin, tragically died after being overcome by toxic gases in his family’s manure holding tank, along with 16 of his cattle. The deadly incident, described by his father, Bob Biadasz, as a “perfect storm,” occurred when a dome of trapped methane or sulfur oxide gas formed due to unusual weather conditions.

According to Portage County Coroner Scott Rifleman, Biadasz had emptied the tank safely hundreds of times before. “The family is devastated, absolutely devastated,” Rifleman said. The gas had become trapped by warm upper air temperatures, creating a lethal dome that prevented dissipation.

In tribute, the Biadasz family lined the farm road with tractors and trucks, including Michael’s black pickup. The accident has sparked renewed calls for stricter safety regulations around manure tanks.

The National Agriculture Safety Database recommends proper ventilation, posted warning signs, and adherence to maintenance procedures. “Owners should follow precautionary measures to protect both workers and livestock from harmful manure gases,” the NASD advises.

This tragedy echoes a 2007 Virginia case where five family members died from methane gas buildup.
