Airborne dust and endotoxin levels on poultry farms, were determined for various working processes known to involve a heavy exposure. Forty-seven workers at different sites were studied by questionnaires for work-related symptoms. Lung function measurements were made before and after work. Dust levels exceeded the standard for organic dust, and endotoxin levels exceeded those known to cause respiratory and other symptoms. The average decrease in FEV1 over the working day(s) ranged from 0.07-0.19 litres. Upper airway irritation was present in one third of the workers, and about 10% complained of chest tightness. The effect may have been due to the high amounts of dust causing a general respiratory irritation as well as to the endotoxin.
对家禽养殖场中已知涉及高暴露的各种工作流程的空气尘埃和内毒素水平进行了测定。通过问卷调查研究了不同地点的47名工人的工作相关症状。在工作前后进行了肺功能测量。尘埃水平超过了有机尘埃标准，内毒素水平超过了已知会导致呼吸道及其他症状的水平。工作日期间第一秒用力呼气容积（FEV1）的平均下降幅度为0.07 - 0.19升。三分之一的工人存在上呼吸道刺激症状，约10%的工人抱怨胸部发紧。这种影响可能是由于大量尘埃导致一般性呼吸道刺激以及内毒素所致。
