Objective To understand the status of food-borne pathogens in various foodstuffs in Mianyang City and to find high-risk foods that may cause food-borne diseases so as to provide evidences for controlling and reducing food-borne diseases. Methods Eight kinds of food-borne pathogenic bacteria were isolated and identified according to the national standard methods and the national foodborne disease monitoring manual. Results A total of 582 food samples were sampled and 49 pathogenic bacteria were detected, with a total detection rate of 8.42%. Among them, 26 strains of Bacillus cereus, 8 strains of Listeria monocytogenes, 4 strains of Enterobacter sakazakii, 4 strains of Pseudomonas aeruginosa, 4 strains of Salmonella and 3 strains of Staphylococcus aureus. Conclusion In 2012-2013, the detection rate of pathogens in dairy and dairy products and infant foods in Mianyang City is relatively high, and the contamination of Bacillus cereus and Listeria monocytogenes is more serious, which should be paid more attention.
