Area and breathing zone samples were analyzed for ammonia (7664417), carbon-dioxide (124389), airborne dust, endotoxins, and microorganisms at poultry confinement houses of David Mayer Poultry Farm (SIC-0251) and other poultry growers in Hobgood, North Carolina, in March, June, and October 1983. The survey was requested by growers in the area due to an increased incidence of eye and throat irritations, headache, shortness of breath, and chest tightness among the growers. Spirometry tests and a respiratory symptom questionnaire were administered to 25 growers. Ammonia concentrations were 6.0 to 13.1 parts per million (ppm) in June and 15 to 80ppm in March and April when windows and doors were closed. The OSHA standard for ammonia is 50ppm. Carbon-dioxide concentrations were below the Federal standards. Total dust concentrations in four area samples exceeded the American Conference of Governmental Industrial Hygienists recommended limit of 10 milligrams per cubic meter. Endotoxin concentrations were 1.6 to 14.0 nanograms per cubic meter. Airborne microorganism concentrations were 2500 to 360000 colony forming units per cubic meter. There were no current standards for endotoxins or microorganisms. No clear association between reported respiratory symptoms, pulmonary function, and exposure was found. The authors conclude that the primary exposure at the poultry farms is to dust and ammonia. Improved ventilation is recommended.
