Abstract
Introduction. Quality and safety of food is a priority task of the state. Detection and prevention of potential hazards at each stage of the food chain is scientifically grounded on the basis of monitoring data and new research methods The goal of the work was to determine the number of waterfowl in Ukraine, the frequency of isolation of food pathogens, the level of bacterial contamination of ducks carcasses and the incidence of foodborne toxicoinfection after the poultry products consumption in different countries of Europe and in Ukraine. Materials and methods. The determination of levels of bacterial contamination of ducks carcasses was carried out by analyzing the results of its own diagnostic studies and analyzing data from the European Food Safety Authority (EFSA) reports on trends and sources of zoonoses, zoonotic agents and antimicrobial resistance in the Community. We have investigated 195 samples of the skin from the neck, chest, and breast meat of ducks carcasses kept in private farms in Ukraine. Samples collected in the state laboratories of veterinary expertize at the markets. Results of research and discussion. In Ukraine, waterfowl mostly held in private farms of the population with an aggressive epizootic environment that requires proper veterinary control. We registered 86.4% of bacterial contamination cases in carcasses of waterfowl poultry. Most of them were caused by the mixed bacterial agents. Monitoring data of Reports of the European Agency for Food Safety demonstrated straight dependence between intestinal colonisation of slaughtered poultry and contaminated carcasses after slaughtering. The levels of microbiological contamination of poultry carcasses were 100–1000 CFU/g in the most of them. The rate of microbiological contamination detection in different countries range from 9.6% to 37.5%. After consumption of poultry, products incidence of people per 100,000 population in the EU was registered in Switzerland – 103.7%; UK – 90.9%; Luxembourg – 90.7%; Finland – 84.0%; Sweden – 83.8%; Germany – 78.7%. In most cases food toxicoinfections have been detected in humans after poultry products consumption. Conclusions and prospects for further research. The highest percentage of poultry kept in conditions of private households – 92.82% and 95.51% respectively. 23.58% samples from poultry carcasses of studied numbers didn’t meet microbiological safety parameters. The number of plants selected Escherichia was 17.39%, Campylobacter spp. – 4.36%, Enterobacter – 13.04%, Citrobacter – 4.35%, Proteus – 23.91, Salmonella – 36.95%. Generalised level of contamination of poultry carcasses in EU countries was 38%. After consumption of poultry products highest incidence of people per 100,000 population in the EU was registered in the Czech Republic – 194.3%; Ukraine – 7.53%. We plan to increase the efficiency of control of the epizootic process of waterfowl depending on the timely detection of the source of the pathogen infection.
