CAMBRIA, Wis. (AP) — The Latest on the fatal mill explosion in southern Wisconsin (all times local):

11:15 a.m.

The Wisconsin corn mill where an explosion late Wednesday killed at least one worker was cited by federal safety investigators six years ago for exposing workers to dust explosion hazards.
Records from the U.S. Occupational Safety and Health Administration show that Didion Milling Plant in Cambria was cited in January 2011 for exposing workers to hazards associated with dust explosion and other fire hazards. The records say filters in the plant lacked an explosion protective system.

OSHA ordered the mill to correct the problem by April 2011. The records don’t clearly indicate whether the company complied but the case was closed in September 2013.

Didion officials didn’t immediately return messages from The Associated Press on Thursday. OSHA has launched an investigation into Wednesday night’s blast.

Authorities say two workers are still missing and about a dozen other workers were injured.

Recovery crews are searching a mountain of debris for two missing employees after a fatal explosion at a corn mill in southern Wisconsin.

Columbia County sheriff’s officials say the explosion and fire at the Didion Milling Plant killed at least one person and injured about a dozen others.

The blast was reported around 11 p.m. Wednesday. Sheriff Dennis Richards says 16 employees were working at the time, and two remained unaccounted for on Thursday morning.

The blast leveled the corn milling structure at the Didion complex in Columbia, a village of about 770 residents roughly 45 miles northeast of Madison.

Some concrete storage silos are damaged but remained standing.

Village President Glen Williams says about three dozen police, fire and rescue agencies responded to the explosion at the complex, which processes corn for ethanol and other industrial uses.

There was no immediate word on the severity of the injuries or what may have caused the blast.
