Abstract:: According to Council Directive 90/ 679/ EEC on the protection of workers from risks related to exposure to biological agents at work, nature, degree and duration of workers' exposure to microorganisms must be determined. This directive has already been implemented in waste and wastewater management. The present case study investigates concentration and composition of microorganisms in a poultry slaughterhouse in the State of Styria, Austria. From June to November 2002, measurements were conducted at the sampling sites ` moving rail' and ` gall bladder separation' using the Andersen six stage viable cascade impactor and the SKC BioSampler. The results of this study were compared with other previous studies which were carried out using the same device ( ACFM) and the same measurement methods. At the processing area of the ` moving rail', the median concentration of airborne mesophilic bacteria was 1.7 x 10(6) CFU/ m(3) which is 8000 times higher than the background concentration of residential areas ( approx. 210 CFU/ m(3)). The airborne microorganisms concentration was 1.7 x 10(4) CFU/ m(3) at composting plants which is 100 times lower than at a workplace of a poultry slaughterhouse. The study shows that poultry slaughterhouse employees are exposed to high concentrations of airborne microorganisms throughout the entire work time without using a respiratory protective device. For the protection of employees against airborne biological agents, relevant measures should be introduced to this field of work.
