In this paper, composition of the air in terms of bacterial bioaerosol in the management of post-slaughter poultry waste, was analyzed. The air samples were collected at 4 dates from 5 different locations – buildings (building for pre-processing with chemical treatment, pool for liquid waste, facility for storage of sludge from biological sewage treatment, object for preparation of waste subject to composting, and proper composting facility). Analyses were carried out in accordance with the procedures of environmental microbiology. Number of total bacteria was determined with particular emphasis put to Pseudomonas sp. and Clostridium sp. as well as Actinomycetes sp. Based on the air assays, it was found that the bacterial bioaerosol was present in varying degrees depending on the selected groups of microorganisms and differed between dates of analyzes and research points i.e. type and purpose of the object for these wastes management.
