SELBYVILLE (AP) — A fire official says one worker was critically injured by a chemical explosion at a poultry processing plant in Selbyville.

Selbyville Fire Chief Matthew Sliwa said by telephone that firefighters were called to the Mountaire Farms plant about 3 a.m. Thursday and one worker was transported to a hospital in critical condition.

Sliwa says the worker mixed two chemicals in a sprayer to clean equipment. He says the chemicals reacted inside the sprayer and exploded, injuring the worker.

Sliwa says no one else was hurt, but others had to be decontaminated.
