MADISON, Neb. (AP) — An ammonia leak briefly disrupted operations at a northeast Nebraska pork plant and sent 40 workers to area hospitals for evaluation.
The ammonia leak developed around 8 p.m. Thursday in the refrigeration system at the Tyson Foods plant in Madison.
Tyson spokesman Gary Mickelson (MIHK'-uhl-suhn) says the plant's 150 workers were evacuated. Forty workers were taken to hospitals as a precaution and later released.
A spokeswoman for Faith Regional Health Services in Norfolk says the hospital treated 10 workers for minor chemical inhalation before releasing them.
The ammonia leak has been repaired, and Mickelson says the plant is operating normally on Friday.
