Detection Analysis on the Foodborne Pathogens in Haidian District of Beijing in 2009-2013

Objective To survey the status and dynamic change of food contamination with foodborne pathogens in Haidian District and to provide scientific basis for disease control. Methods Food of 20 types were collected in Haidian District ac cording to the requirements of Beijing monitoring net. 8 kinds of foodborne pathogenic bacterium, such as Salmonella, Staphylococcus aureus , Listeria monocytogenes , EHEC O157 ： H7/NM, Campylobacter jejuni , Vibrio parahemol yticus , Vibrio vulnficus and Enterobacter sakazakii were detected according to the international method in 2009-2013. Results 52 strains of foodborne pathogens in 19 types of food were isolated from 822 samples,the overall positive rate was 6.33%. The strains of Vibrio parahemol yticus , Staphylococcus aureus , Listeria monoc ytogenes and Vibrio vuln f icus were 24,14,12 and 2 respectively. Conclusion The foods in Haidian district were contaminated by several foodborne pathogens in diffferent degrees,which was a hidden danger that could induce food poisoning and foodborne disease. It was suggested that surveillance and management should be improved to get rid of the risk factors asssociated with foodborne diseases.
