摘要：

Enterobacter sakazakii has recently been recognized as an opportunistic foodborne pathogen, and dry infant formula serves as the mode of transmission. The objectives of this study were to investigate the heat resistance, survival and inactivation under room and refrigeration temperatures storage of dry and reconstituted infant formula milk (IFM). E. sakazakii strains (eight strains) showed a wide variability in heat resistance at different temperatures (55, 60 and 63C). The D-values at 55C ranged from 1.51 to 14.83 min, at 60C from 0.17 to 2.71 min and at 63C from 0.05 to 0.88 min. The calculated z values for the studied E. sakazakii strains ranged from 3.76-10.11C. Microwave oven heating of 60-mL portions of reconstituted IFM for 40-50 s was effective in eradicating inoculated E. sakazakii. Storing powdered IFM for 15 days at 4C resulted in at least a 1-log reduction in E. sakazakii strains, whereas storing reconstituted IFM at 4C for 2 weeks resulted in more than a 2-log reduction in E. sakazakii.
