Seventy firefighters from eight stations and five fire departments in Audrain County responded to a grass and structure fire Tuesday afternoon.
Officials are unsure of the cause of the fire at McGee Packing Co., two miles north of Mexico, Mo., on Route J, said Kenneth Hoover, Little Dixie Fire Protection District chief.
Hoover said a call was received at 1:51 p.m. and that one firefighter received a minor injury but was treated on the scene.
A secondary storage facility had burned to the ground, and the main processing plant also was in danger of catching fire, Hoover said.
Acres of wilderness, along with several thousand packing palettes and electric and telephone poles in the area, also were damaged, Hoover said.
By Tuesday evening, no flames were showing , but several units were going to stay on the scene to deal with smoldering palettes, Hoover said.
Personnel from the Audrain Medical Center, Missouri Department of Natural Resources and the American Red Cross also helped in the effort, Hoover said.
