Title Farmers' exposure to airborne microorganisms in composting swine confinement buildings
Bibliographic information Sep.-Oct. 2003, Vol.64, No.5, p.673-677. 25 ref.
Abstract Exposure to airborne microorganisms was studied in 12 composting swine confinement buildings and in seven buildings with traditional slatted-floor pit systems. Airborne cultivable mesophilic, xerophilic, and thermotolerant fungi, mesophilic bacteria and thermophilic actinobacteria were determined using a six-stage impactor. Total concentrations of microorganisms were determined with filter sampling and direct counts using a microscope. In swine confinement buildings where the composting system was functioning properly, the concentrations of microorganisms were 10-1000 times higher than in traditional swine buildings. High concentrations were found of thermotolerant fungi and thermophilic actinobacteria (up to 105CFU/m3), considered to be the main causative agents of farmer's lung, in the composting swine confinement buildings that were studied. Therefore, personal protection is strongly recommended in composting swineries, especially during the turning of the compost bed.
