Abstract：Objective To investigate the contamination status of food-borne pathogenic bacteria in food in Liwan District, Guangzhou City from 2010 to 2015 so as to provide a scientific basis for prevention of food-born diseases. Methods Nine categories of food samples were collected from supermarkets, restaurants, farmers’ markets and bakeries in Liwan District, Guangzhou City during 2010-2015, and 9 species of pathogenic bacteria were detected, including Salmonella, Staphylococcus aureus, Listeria monocytogenes, Vibrio parahaemolyticus, Vibrio vulnificus, Bacillus cereus, Escherichia coliO157, diarrheogenic Escherichia coli and Shigella. Results Three hundred and sixty-four samples were collected from 9 categories of food, and 34 strains of food-borne pathogenic bacteria were detected in 29 food samples, with the total detected rate of 7.97%. The detected rates of food-borne pathogenic bacteria in raw seafood, pastry, cooked meat products, cold vegetable dish in sauce and Chinese fast food were 20.93%, 16.67%, 4.00%, 3.33% and 2.50% respectively. The detected rate of Vibrio parahaemolyticus in raw seafood was the highest (19.77%), followed by Bacillus cereus in pastry (13.89%). Conclusions There are different degrees of contamination of food-borne pathogens in partial food in Liwan District, Guangzhou City; and hence, it is necessary to enhance the supervision and management of food production, circulation, storage and other links and adopt effective measures to prevent the occurrence of food-borne illness.
