Abstract
Two bioaerosol sampling methods (Andersen sampler and filtration sampler) were compared. The two samplers were used to assess the bioaerosol loads in two swine finishing barns. They were similar in terms of the species of microorganisms sampled. The persistent strains of microorganisms were various species of the following genera: Staphylococcus, Pseudomonas, Bacillus, Listeria, Enterococcus, Nocardia, Lactobacillus, and Penicillium. However, the use of Andersen sampler resulted in significantly higher bioaerosol concentrations than the filtration sampler. Thus, it appears that filtration sampling can be used for a qualitative survey of bioaerosols in swine barns while the Andersen sampler is suitable for both quantitative and qualitative assessments.

Summary
Bioaerosols include airborne particles that are living, as well as large molecules and volatile compounds that were released from a living organism. Previous studies have documented considerably higher bioaerosol concentrations in animal houses than in industrial, residential or ambient settings. Inhalation of bioaerosols can be detrimental to health through infection, allergy or toxicosis. There is a need to assess potential health risks by measuring workplace exposure to bioaerosols. Various bioaerosol assessment methods have been reviewed and the characteristics of the different bioaerosol sampling devices have been evaluated. Standard methods for bioaerosol assessment have not been established and no bioaerosol sampler has been fully characterized in terms of its physical and biological sampling efficiencies. In the absence of standard methods, existing methods should be validated
