Several fire departments and a HAZMAT team responded to the Tyson Foods chicken processing plant in Noel, MO on Wednesday morning after an ammonia leak was reported in the facility, local news organizations reported.
Crews were called to the Tyson Drive facility at about 6 a.m. and remained on scene until about 8 a.m., according to coverage by WWLP. Reports did not have any information available on possible injuries.
“The leak is isolated and contained, we are working to ventilate the building now,” fire officials told the news broadcaster at about 7 a.m.
