摘要
目的通过对乌鲁木齐零售牛羊中的沙门氏菌检测分离并分型,了解乌鲁木齐市牛羊肉的污染状况。方法按照沙门氏菌检验国家标GB/T 4789.1-2010对乌鲁木齐零售牛羊肉检测分离并进行血清型分型。结果2013~2014年共检测535份零售牛羊肉样品,共分离得到30株沙门氏菌,总体感染率为5.6%,羊肉的感染率为6.5%,牛肉感染率为4.3%,经血清分型鉴定可以分为5个血清群,12个血清型主要有哈达尔沙门氏菌、伦敦沙门氏菌、肠炎沙门氏菌、姆班达卡沙门氏菌和哈瓦那沙门氏菌等。结论新疆乌鲁木齐地区零售牛羊肉中存在沙门氏菌污染,沙门氏菌菌株为不同的表型,需要加强对零售牛羊肉市场的卫生检疫,防控沙门氏菌疾病。
Objective To investigate the contamination situation and understand the dynamic changes of Salmonella in lamb and beef meats, the foodborne Salmonella in retail meats in Urumqi was detected and analyzed. Methods The Salmonella in retail lamb and beef meats were isolated, identified and further serotyped according to National Standard GB/T 4789.1-2010. Results A total of 30(5.6%) strains of Salmonella were detected among 535 samples during 2013 to 2014, and the infection rate of Salmonella was 6.5% in lamb and 4.3% in beef. Five serogroups and 12 serotypes were identified as S. hadar, S. lundon, S. enteritidis, S. mbandaka, and S. havana. Conclusion The contamination of different Salmonella phenotypes existed in retail lamb and beef meats in Urumqi, and could not be ignored. The hygiene and quarantine of retail meats should be strengthened to prevent and control the Salmonellosis.
