On Thursday, a liquid nitrogen spill at a poultry plant in north-east Georgia killed six people, with dozens being admitted to the hospital.
Five people died at Prime Pak Foods near Gainesville, a Northeast Georgia health system spokeswoman said, and another died after being admitted to the hospital.
The leak occurred after 10am, Zach Brackett, the chief of the Hall county fire department division, said.
He said firefighters had arrived, some with injuries, to find workers milling around outside.
At least four firefighters with what were identified as respiratory complaints were hospitalized and transported to the Gainesville hospital. Brackett said some 130 staff were brought to a local church by bus, where they were checked for injuries, and some were taken to the hospital afterwards.
Hall county education administrators said that inside a local elementary school, students were kept safe and said the spill was localized and not airborne. The lane that runs in front of the plant and school was blocked for around 1.5 miles.
Prime Pak Foods has merged into Foundation Food Group, a firm that takes raw chicken and transforms it for restaurants and food service operations into products such as chicken fingers and individual chicken cuts.
A phone call requesting comment was not promptly answered by the company’s CEO.
Gainesville is the hub of the poultry industry in Georgia, the largest in the country, with thousands of workers employed for several processing plants.
