Missouri Pork Plant Blast Kills One, Injures 14

Police now say at least one person has died, and 14 are injured, in this afternoon's explosion at a pork processing plant (search) under construction in St. Joseph.

Police Chief Mike Hirter says in addition to the death one person is critically injured. But the chief also says that rescue workers believe they have accounted for everyone inside the Triumph Foods (search) plant.

Hirter says the explosion might have been caused by a welding torch. The blast ripped a 150-foot hole in the roof.

The Heartland Regional Medical Center has called in extra staff to treat the injured.

The Triumph Foods plant is the largest development in St. Joseph in decades. It had been expected to open this fall, employing one-thousand to 15-hundred workers.
