An ammonia leak at a Tyson Foods plant in Goodlettsville, Tennessee, led to the evacuation of the facility around 5:30 a.m. on May 18.
According to a statement issued to reporters by Tyson Foods, the plant was not in operation at the time, but there were about 125 Tyson employees and sanitation contract workers inside.
Fox 17 reported that six people complained of irritation, and two were transported to the hospital.
Operations resumed the same day.
The facility in Goodlettsville, which produces case-ready beef and pork products, several years ago underwent a $15.5 million expansion.
