Microbiological evaluation of wastewater of processing work shop of industrial poultry plant

The purpose of the study was integrated microbiological assessment of the wastewater from various sectors of a poultry-processing work shop, which is part of chicken farm of Western Siberia region to identify in its taxonomic diversity of microorganisms. The objects of the study were technical wastewater from three main production sites: for poultry slaughter, butchering meat and also sector for washing packaging and equipment. The samples for microbiological analysis were selected in sterile container. The assessment of the wastewater sample was conducted with the guidance methodology sheets about organization State Public Health Inspectorate about decontaminated wastewater "MR 2.1.5.800-99", and also the guidance about identification veterinary important microorganisms. overall microbial number, number of overall and thermo-latent coliform bacterial, availability of salmonella, streptococcus, listeria, bacillus and mould fungi were identified. The studies revealed that the highest rate of overall microbial number was in the sample from the poultry slaughter sites wastewater and in offal sites wastewater. The lowest overall; microbial number was in the sample from washing packaging. The overall microbial number from the poultry slaughter and offal sites had more of 17.0 and 42.6 %, than on butchering meat and washing packaging sites. At the same time the lowest sample of the number thermo-latent coliform bacterial was in the wastewater sample from washing sites and the highest - in the sample from butchering meat and offal sites. The fungi Aspergillus spp. were isolated in the poultry slaughter sites wastewater and were not found in washing packaging sites wastewater. The hightest salmonella number was found in the wastewater sample from the butchering meat and offal sites, and lowest - in washing packaging sites. Nevertheless the microorganism Listeria spp. was not found in any wastewater sample of technological plots of the poultry processing plant.
