Working in poultry farms revealed the exposure to chemical and biological emissions (bioaerosols) that might be related to respiratory diseases in the workers and an increased loss in lung function. The current study aimed to determine the respiratory health status among poultry farm workers and to monitor the biological and the environmental conditions at ten poultry farms in Egypt. It reported that the total dust, ammonia (NH₃), and carbon dioxide (CO₂) concentrations in the studied poultry farms did not exceed the permissible exposure limits except farm V where NH₃ was slightly exceeded the recommended levels. 35.7% of the poultry farm workers had positive nose and throat culture (bacterial and fungal). The poultry farm workers had higher prevalence of cough, wheeze, and shortness of breath with lower mean values of spirometric measurements than the controls (P < 0.05). Also, the positive culture poultry farm workers had significantly higher respiratory manifestations and lower spirometry values than negative culture ones (P < 0.05). Therefore, intervention programs for reducing the exposure are amendatory point for the health and safety of poultry farm workers.

在养禽场工作表明，暴露于化学和生物排放物（生物气溶胶）可能与工人的呼吸系统疾病和肺功能丧失增加有关。当前的研究旨在确定家禽农场工人的呼吸健康状况，并监测埃及十个家禽农场的生物学和环境状况。它报告说，所研究的家禽养殖场中的总粉尘，氨气（NH ₃）和二氧化碳（CO ₂）的浓度未超过允许的暴露极限，而养殖场V中的NH ₃略高于建议水平。35.7％的家禽农场工人的鼻和咽喉文化（细菌和真菌）阳性。家禽农场工人的咳嗽，喘息和呼吸急促发生率高于对照组，肺活量测量平均值较低（P  <0.05）。而且，阳性养殖家禽农场工人的呼吸表现和肺活量值明显低于阴性养殖农场工人（P  <0.05）。因此，减少接触的干预计划是家禽农场工人健康和安全的修正点。
