The results showed that six samples were separated Enterobacter sakazakii, 24 samples were separated Enterobacteriaceae by using the traditional validation and real-time fluorescence quantitative PCR. Then the result identified by API20E biochemistry test and VITEC2 identification system. Through the study we concluded the potential safety hazard of the current infant formula powder and should regard Enterobacteriaceae as an indicator to carry out effective management, the neglected mild and discontinuity contamination could be easily found, thus to guarantee the safety of the special group.展开更多
