(AP) - Officials say workers were evacuated at two northwest Arkansas meat processing plants due to ammonia leaks.

Springdale plants owned by Cargill Inc. and Tyson Foods Inc. each evacuated workers Monday morning after apparently unrelated ammonia leaks.

Cargill plant manager Heath Ward told the Arkansas Democrat-Gazette  that a pipe broke in an area of the plant where work was being done on the cooling system.

About 500 workers were evacuated. Ward says no one was hurt.

A Tyson Foods spokesman said 10 workers were taken to a hospital as a precaution after a freezer line leak at the plant.

The leak occurred at about 9:30 a.m.

Fire officials cleared the plant for re-entry at 10:20 a.m. but the company was further evaluating conditions before bringing workers back in.
