Significant microbial contamination occurs in pig houses, poultry houses and cowsheds. The microbes most frequently isolated from the air of these buildings are bacteria of the genera Streptococcus, Staphylococcus, Bacillus, and Clostridium and of the family Enterobacteriaceae. Among fungi, the most common are Aspergillus, Trichoderma, Penicillium, Cladosporium and Alternaria.

Bacterial endotoxins may also pose a threat to humans and animals. For this reason it is important to carry out microbiological monitoring and preventive measures on livestock farms and to maintain appropriate environmental conditions.
