DECATUR, ILL. — Several employees were injured in an explosion at an ADM processing plant Sept. 10 in Decatur, the company said.

ADM said the explosion occurred at 19:11 at the East Plant in the processing complex on the northeast side of the city.

“ADM immediately contacted the fire department…Several employees were injured and transported to a local hospital for treatment,” ADM said. “Our thoughts are with our colleagues.”

It is not clear what caused the explosion, nor is the extent of the damage known. Reuters reported eight injuries, citing the Decatur Fire Department, which added that the fire was under control early Monday morning.

This is the third incident this year reported at the Decatur site, home to a soybean crushing facility and one of the largest wet corn mills in the world for Chicago-based ADM.

In April, three employees were injured in an explosion in one of the grain elevators at ADM’s West Plant soybean processing facility.

Last month, two Decatur firefighters were injured while battling a third-alarm fire at the company’s corn processing plant storage facility.

Decatur, about 280 miles south of Chicago, is home to ADM’s North American headquarters and employs about 4,000 local workers, about 10% of the global workforce.
