The aim of the presented study was to assess the exposure of poultry workers to airborne microorganisms, endotoxins and β-glucans during different stages of the chicken production cycle in 3 commercially-operated poultry houses. Personal and stationary sampling was carried out to assess exposure to both viable and total microbial aerosols. The stationary measurements of PM10 were performed to establish the level of endotoxins and β-glucans. The concentrations of bacterial and fungal aerosols ranged from 2.5×10(2) CFU/m(3)-2.9×10(6) CFU/m(3), and from 1.8×10(2) CFU/m(3)-1.8×10(5) CFU/m(3), respectively. The number of culturable microorganisms was significantly lower than their total counts, constituting from 0.0004%-6.4% of the total microbial flora. The level of PM10 in poultry facilities did not exceed 4.5 mg/m(3). After the flock entered the clean house, the level of endotoxins and β-glucans increased from below detection limit to 8,364 ng/m(3) and from 0.8 ng/m(3) to 6,886 ng/m(3), respectively. The presented study shows that professional activities in poultry farms are associated with constant exposure to bioaerosol, which may pose a health hazard to workers. It was found that workers' exposure to airborne microorganisms increased with consecutive stages of the chicken production cycle.
本研究的目的是评估在3个商业运营的禽舍中，家禽养殖工人在养鸡生产周期不同阶段暴露于空气传播微生物、内毒素和β-葡聚糖的情况。进行了个人和固定采样，以评估对活菌和总微生物气溶胶的暴露情况。对PM10进行了固定测量，以确定内毒素和β-葡聚糖的水平。细菌和气真菌溶胶的浓度分别为2.5×10(2) CFU/m(3)-2.9×10(6) CFU/m(3)和1.8×10(2) CFU/m(3)-1.8×10(5) CFU/m(3)。可培养微生物的数量明显低于其总数，占总微生物菌群的0.0004%-6.4%。家禽养殖设施中的PM10水平不超过4.5 mg/m(3)。鸡群进入清洁舍后，内毒素和β-葡聚糖的水平分别从低于检测限增加到8364 ng/m(3)和从0.8 ng/m(3)增加到6886 ng/m(3)。本研究表明，家禽养殖场的专业活动与持续暴露于生物气溶胶有关，这可能对工人的健康构成危害。研究发现，随着养鸡生产周期的连续阶段，工人暴露于空气传播微生物的情况增加。
