Federal jury convicts two employees in fatal Wisconsin corn mill explosion

MADISON, Wis. (AP) — A federal jury has convicted two senior employees at a Wisconsin corn plant of falsifying records and obstructing an investigation into a fatal corn dust explosion in 2017, Justice Department officials announced on Tuesday.

Corn dust is explosive, and high concentrations are dangerous. Federal regulations require grain mill operators to perform regular cleanings to reduce dust accumulations that could fuel a blast.

Jurors found Derrick Clark, vice president of operations at Didion Milling, and Shawn Mesner, a former food safety superintendent at the company, guilty of multiple safety, environmental and fraud charges on Friday. The two men are the latest in a growing list of Didion employees found guilty in association with the 2017 explosion that killed five people at the company's Cambria corn mill.

Attorneys listed for both men did not immediately respond to voicemails seeking comment on Tuesday.
