Seven workers at a Hain Pure Protein plant in Fredericksburg, Pennsylvania, were sent to the hospital after an ammonia leak was discovered in the building.
The leak was found around 1 a.m. on May 1.
According to PennLive, after the leak was found, workers closed the necessary valves and contacted a refrigeration company to make repairs. The plant, which had about 140 people working at the time, was evacuated, and the building was ventilated until it was safe for employees to work.
Condition updates on the seven patients were not available.
The plant processes FreeBird chicken products, which are raised without antibiotics. Hain Pure Protein, which according to the WATTAgNet Top Poultry Companies Database, processed 1.77 million pounds of ready-to-cook chicken on a weekly basis in 2016 is a subsidiary of Hain Celestial.
