Abstract：Objective To analyze the status of major microbial contamination in food in Zhengzhou City from 2016 to 2018, and to provide a scientific basis for prevention of food-borne diseases. Methods According to the National Food Safety Standard of Food Microbiological Examination and referring to the Manual for China National Food Contamination and Harmful Factors Risk Monitoring, a total of 561 food samples collected in Zhengzhou city were examined for pathogenicbacteria. Results A total of 561 food samples were detected in Zhengzhou city from 2016 to 2018. 49 samples showed to be positive for pathogenic bacteria, with the positive sample rate of 8.73%. 51 strains of food-borne pathogens were detected, and the detection rate of strains was 9.09%. Bacillus cereus was the most common pathogen among the detected strains, accounting for 41.81% of the total positive strains, followed by 10 strains ofSalmonella (19.60%). Among the 10 categories of food samples, the positive sample rate of food and beverage was the highest (15.83%), followed by meat and meat products (15.15%), fruits and their products (10.00%), soybean products (8.89%), special dietary food (6.13%) and condiments (3.45%). As for the distribution of sampling sites, the positive sample rate in collective canteens was found to be the highest, followed by small shops around schools and street stalls. Conclusions Food-borne pathogen contamination was existent in food sold in markets in Zhengzhou city during 2016-2018, and the main contaminating bacteria were Bacillus cereus and Salmonella. The results suggest that continuously monitoring of food-borne pathogens in food and beverage, meat and meat products, and fruits and their products should be conducted, and supervision and management of collective canteens, small shops around schools and street stalls should be enhanced.
