摘要:

目的:了解福建省市售婴幼儿配方奶粉中阪崎肠杆菌的污染状况、污染途径并寻找快速准确的检测方法。方法:应用分离鉴定、PCR 和荧光PCR 等方法检测,分离鉴定采用阪崎肠杆菌显色培养基和全自动微生物生化仪。结果:阪崎肠杆菌在192 份市售婴幼儿配方奶粉中的检出率为1.56%,在60 份原料奶粉中的检出率为13.33%,30 份生产车间环境样本均未检出。结论:福建省市售婴幼儿配方奶粉中存在阪崎肠杆菌的安全隐患,某工厂奶粉中阪崎肠杆菌的污染主要来自原料奶粉。荧光PCR 和显色培养基可用于阪崎肠杆菌的快速筛选和分离。

Abstract:

Objective: To realize the status of Enterobacter sakazakii contamination in infant formula milk powder, and to study relevant contamination routes and rapid detection methods. Methods: Enterobacter sakazakii colored medium and VITEK automatic microbial biochemical analyzer were used in isolation and identification, PCR and fluorescence PCR were used for detection. Results: The detection rate of Enterobacter sakazakii is 1.56% in 192 infant formula milk powder product samples, 13.33% in 60 material samples and 0% in 30 environment samples in production, respectively. Conclusion: There are hidden safety questions in Fujian infant formula, and most contaminations are from material. Moreover, fluorescence PCR and colored medium can be used for rapid isolation and identification of Enterobacter sakazaki in infant formula milk powder.

Key words: infant formula milk powder, Enterobacter sakazakii, contamination, fluorescence PCR
