Abstract

This paper describes the concentrations of airborne bacteria and fungi in a cage housed laying hens facility, during a production year. Levels of airborne bacteria established in the air of the poultry house ranged from 1.02×10 4 CFU/m3 measured in April, to 7.72×10 4 CFU/m3 measured in December. Mean values of the total number of fungi ranged from 0.075×10 4 CFU/m3 measured in September, to 8.56×10 4 CFU/m3 measured in June. Established values of air temperature, relative humidity and air velocity were, generally, in accordance with the technology-predicted ranges. The determined number of bacteria and fungi in the air, as well as the statistically significant impact of microclimate conditions on their number in the air of the cage housed laying hens facility, are in accordance with considerations for standards set for air quality in livestock buildings and the development of reliable systems for monitoring the above factors. The aim is to create production that, besides the economic aspects, must include the protection of animals and people, as well as safety of food and environmen
