The exposure of chicken growers, catchers, and hangers daily to airborne contaminants in the poultry processing industry was examined. Personal samples collected at 22 North Carolina poultry farms for 26 growers showed geometric mean 8 hour time weighted average (TWA) concentrations of 11.6mg/m3 for inhalable dust, inhalable endotoxin, 3ng/m3 for respirable endotoxin, and 19 parts per million (ppm) for ammonia (7664417). Personal sampling of 36 chicken catchers produced geometric mean 8 hour TWA concentrations of 20.2mg/m3 for inhalable dust, 1.75mg/m3 for respirable dust, 250ng/m3 for inhalable endotoxin, 13ng/m3 for respirable endotoxin, and 6ppm for ammonia. The personal sampling of six chicken handlers produced geometric mean 8 hour TWA concentrations of 17mg/m3 for inhalable dust and 830ng/m3 for inhalable endotoxin. The authors conclude that the North Carolina poultry growers, catchers, and hangers may be at risk of experiencing respiratory dysfunction. The authors recommend the use of respiratory protective equipment for poultry growers and catchers, and local exhaust ventilation for poultry hangers.
