Analysis of food-borne pathogen contamination situation in retailed food in Guangzhou in 2010

Objective:To understand the contamination status of food-borne pathogenic bacteria in main food in Guangzhou,find out the pathogen source and predict the food-borne disease.Methods:Based on the standard operation procedures in the handbook of National Surveillance on Food-borne Pathogenic Bacteria,seven kinds of food samples were collected for detection of Salmonella,Listeria monocytogenes and Vibrio parahaemolyticus.Results:264 samples were detected,64 strains of pathogens were detected with an overall positive rate of 24.24%.Vibrio parahaemolyticus had the highest positive rate of 37.50%(24 /64),Listeria monocytogenes had the positive rate of5.91%(14 /237),the positive rate of Salmonella was 12.12%(32 /264).Conclusion:The contamination status of food-borne pathogenic bacteria in main consumption of food in Guangzhou was serious.The study on risk factors of food-borne disease and the predictive warning on food safety should be enforced.
