Abstract:OBJECTIVE To master the contamination status of foodborne pathogenic bacteria in food in Jiamusi city, and provide a ba⁃ sis for relevant departments to formulate prevention and control measures. METHODS According to the national pollution and harmful factors in risk monitoring handbook, adopts the method of random sample collection, sample processing, enrichment, separation and identification such as operation, respectively for salmonella, deputy hemolytic vibrio, mononuclear cell hyperplasia liszt bacteria, bacil⁃ lus cereus and staphylococcus aureus, detection and jejunum bending test and analysis of test data. RESULTS there was no significant difference in the detection rate of pathogenic bacteria in different years from 2015 to 2018(χ2=6.95, P=0.07).In the 4 years, the annual detection rate of campylobacter jejuni was the highest(28.93%) and the lowest(1.76%), and the difference was statistically signifi⁃ cant(χ2=240.75, P＜0.01). Pre-packaged food detection rate(26.12%) than in bulk food(15.44%), the difference was statistically sig⁃ nificant(χ2=240.75, P＜0.01), infants born system class food grains and pathogenic bacteria detection rate (80.00%) than than other types of food, the difference was statistically significant (χ2=235.43, P＜0.01), circulation pathogenic bacteria detection rate(25.43%) than other link detection rate, difference was statistically significant(χ2=87.90, P＜0.01); By comparing the detection rate of pathogen⁃ ic bacteria in different sampling sites, it was found that the detection rate of food in the online store was the highest(30.19%), and the difference was statistically significant(χ2=75.22, P＜0.01). CONCLUSION The contamination of food pathogenic bacteria was common in jiamusi city, and the contamination of infant and infant cereals auxiliary food, meat and meat products were serious.
