Description: Conventional pig-housing facilities expose farmers to high concentrations of microorganisms, organic dusts, and gases, all of which are suspected of causing health problems. A recent method of growingfinishing has been developed which relies upon the use of biotreated litter, i.e. litter composed of solid waste, sawdust or straw, and a biotechnologically produced enzyme that acts on ammoniacal nitrogen in pig manure to stimulate fermentation. The surface of the litter is stirred once a week to maintain aerobic conditions within the litter. The deep-litter method is supposed to produce compost which can be used to improve the physical, chemical, and biological properties of soil. This project was undertaken to measure the chemical and biological contaminants present in the air of a grower-finisher pig building using the deep-litter method and assess the safety of these workplaces for workers. While the concentrations of contaminants usually found in pig-housing facilities, such as Gram-negative bacteria and gases, were within acceptable limits, this type of facility offers ideal conditions for the proliferation of thermophilic actinomycetes andA.fumigatus. Given the unresolved risks associated with thermophilic actinomycetes and A. fumigatus, it is recommended that workers in this environment wear HEPA-equipped (High Efficiency Particulate Air Filters) masks capable of capturing 99.7% of the spores.
