Abstract The poultry industry in the United Kingdom involves a range of activities including laying litter, populating with young birds, depopulating (reducing bird density during growth or removing at the end of the cycle), litter/manure removal, cleaning houses after depopulation, and routine maintenance and housework. The objective of this study was to measure workers' exposure to airborne dust and bioaerosols associated with these tasks in a representative cross-section of commercial poultry production. In total, eleven sampling visits to eight different farms were undertaken. The results showed that, at maximal exposure, poultry workers were exposed to total inhalable dust levels exceeding 10 mg/m3 during most activities. Exposure to airborne bacteria potentially exceeded one million cfu/m3 of air in each of the activities monitored. Maximal endotoxin levels ranged according to task from 30 to more than 38,000 EU/m3. Maximal airborne fungal concentrations ranged from 2,000 to 600,000 cfu/m3. Implications of these findings are discussed.
