One person has been injured in a grain elevator explosion at a feed yard in south central Nebraska.

The explosion occurred Wednesday morning at Dawson Feeders in Lexington. Office Assistant Tracey Johnson says Zellidhay Villatoro was working when she was burned in the explosion. She is being treated at the burn center at Saint Elizabeth Regional Medical Center.

Authorities have not released more details.  Lexington Fire Chief Dahlas Holbein says the blast destroyed the upper portion of the building, but it did not cause a fire.

Regina Shields with the Nebraska State Fire Marshal’s Office says the explosion has been deemed an accident. She says the old wooden elevator was being used as a feed mill.
