2010—2012年新疆乌鲁木齐地区零售生肉中沙门菌污染情况调查

通过对2010—2012年新疆乌鲁木齐地区零售生肉中沙门菌的检测分析,了解沙门菌污染情况,掌握乌鲁木齐地区零售肉品中沙门菌污染动态变化。方法 按照沙门菌检验国家标准GB/T 4789.1—2010对乌鲁木齐地区的零售肉(鸡肉、羊肉、牛肉、猪肉)检测分离沙门菌并进行血清型分型。结果 2010—2012年共检测1406份零售生肉样品,生鸡肉的感染率达到9.14%,生猪肉为9.06%,生羊肉为8.05%,生牛肉为6.44%,检测共分离得到123株沙门菌,经血清型鉴定可以分为4个血清群,7种血清型,分别为肠炎沙门菌(n=17)、萨奥沙门菌(n=9)、塔西沙门菌(n=8)、乌干达沙门菌(n=6)、康科德沙门菌(n=3)、汤姆逊沙门菌(n=3)和德尔卑沙门菌(n=2),未定型沙门菌75株。结论 新疆乌鲁木齐地区零售肉类中存在沙门菌污染,沙门菌菌株为不同的表型,地区内生肉品中沙门菌污染不容忽视,需要加强对零售肉市场的卫生检疫,防控沙门菌病。

Investigation of Salmonella contamination in retail meats in Urumqi, Xinjiang in 2010-2012

In order to investigate the contamination situation and understand the dynamic changes of Salmonella contamination in food, the food-borne Salmonella in retail meats was detected and analyzed during 2010and 2012in Urumqi, Xinjiang.MethodsThe Salmonella in retail meats (chicken, lamb, beef, pork) was isolated, identified and further serotyped according to National Standard GB/T 4789.1-2010. ResultsA total of 1406samples of retail meats were examined from 2010to 2012, the infection rate of Salmonella was 9.14% in chicken, 9.06% in pork, 8.05% in mutton and 6.44% in beef. Among 123strains recovered in the study, 4serogroups and 7serotypes were identified as S.Enteritidis (n=17), S.Sao (n=9), S.Tarshyne (n=8), S.Uganda (n=6), S.Concord (n=3), S.Thomson (n=3) and S.Derby (n=2), undefined 75seroproups.ConclusionThe contamination of different Salmonella phenotypes existed in retail meats in Urumqi and could not be ignored, and the hygiene and quarantine of retail meats should be strengthened to prevent and control the salmonellosis.
