ANALYSIS OF AIR QUALITY IN SELECTED AREAS OF A POULTRY PROCESSING PLANT WITH THE USE OF A MICROBIOLOGICAL AIR SAMPLER

ABSTRACT The aim of the study was to analyze the air quality in selected production facilities specified as the so-called "high-risk zones". Air samples were analyzed using either the sedimentation or the impaction methods. The impaction method showed the applicability of the air sampler in in-situ measurements. An increase in the numbers of aerobic bacteria was observed in most air sample collection sites as the duration of the production time increased. At the three successive dates, it amounted to 163 cfu/m3, 205 cfu/m3, and 324 cfu/m3, respectively. Such dependence was not observed by the ...
