2014年四川省食源性致病菌监测现状分析

Surveillance Results of Food-borne Pathogens in Sichuan Province in 2014

目的了解四川省食品中食源性致病菌现状情况,为食源性疾病监测提供科学依据。方法依据《食源性致病菌监测工作手册》对2014年采集的7大类样品,共2 217份样品进行沙门菌、金黄色葡萄球菌、蜡样芽孢杆菌、阪崎肠杆菌、致泻大肠埃希菌、单核细胞增生性李斯特菌,铜绿假单胞菌进行检测。结果共监测2 217份样本,检出了致病菌173株(155个样本中),致病菌检出率为6.99%,其中单核细胞增生性李斯特菌39株,检出率为9.18%;金黄色葡萄球菌43株,检出率为5.99%;沙门菌17株,检出率为1.06%;铜绿假单胞菌30株,检出率为11.90%;蜡样芽胞杆菌44株,检出率为12.02%。肉与肉制品,巴氏消毒乳,饮用水和婴幼儿配方食品致病菌检出率较高,分别为17.51%、13.73%、11.90%和9.88%。结论 2014年四川地区居民消费的一些食品中检出有食源性致病菌,尤其是在肉类产品、饮用水、巴氏杀菌乳和婴幼儿配方食品中。建议卫生监督执法部门加强监管,减少食源性疾病的发生。

Objective To investigate the current situation of food -borne pathogens in Sichuan Province and pro- vide scientific evidence for surveillance. Methods According to the Manual for Surveillance of Food - borne Pathogens, 2 217 samples of 7 classes collected in 2014 were subjected to tests for Salmonellae, Staphylococcus aureus, Bacillus cereus, Enterobacter sakazakii, Escherichia coli, Listeria monocytogenes and Pseudomonas aeruginosa. Results 173 pathogenic strains were detected from 155 of the 2 217 samples, and the total detec- tion rate was 6.99%. 39, 43, 17, 30, and 44 strains of Listeria monocytogenes, Staphylococcus aureus, Sal- monellae, Pseudomonas aeruginosa and Bacillus cereus were detected, and the detection rates were 9. 18%, 5.99% , 1.06% , 11.90% and 12.02% , respectively. The detection rates of pathogens from meat and meat products, drinking water, pasteurized milk and infant formula were high, being 17.51% , 13.73% , 11.90% and 9.88%, respectively. Conclusion Foodborne pathogens were detected from some foods （in particular meat products, drinking water, pasteurized milk and infant formula） consumed by residents in Sichuan Province in 2014. It is suggested that health regulatory authorities enhance supervision to reduce the incidence of food - borne diseases.
