Enterobacter sakazakii was initially referred to as yellow-pigmented Enterobacter cloacae and

reclassified in 1980. E. sakazakii infection cause life-threatening meningitis, septicemia, and necrotizing enterocolitis

in infants. Powdered infant formula (PIF) and baby foods may be the important vehicle of E. sakazakii infection. It

has been reported that E. sakazakii was isolated from PIF and sunsik ingredients produced in Korea. Some infants

have been fed sunsik as a weaning diet. Therefore, it is necessary that this organism should be inactivated on preparing

PIF and sunsik at homes and in hospitals. The cocktail of three Korean E. sakazakii strains (human, sunsik and soil

isolates) were used to investigate the inactivation of this organism with hot water at 50, 60, 65, 70 and 80℃ and microwave

heating for 60, 75, 90, 105 and 120 sec. Reconstituted PIF and sunsik were inoculated with cocktailed vegetative

cells of E. sakazakii at 6 log CFU/mL. Thermal inactivation of vegetative cells of E. sakazakii were achieved by

reconstituted PIF and sunsik with hot water at 60℃ or greater and with microwave heating at 2,450 MHz for 75 sec

or longer. Considering that biofilm formation of E. sakazakii was adapted to survive the dry environment that is PIF

and sunsik and thermal resistance increased, it is suggested that inactivation of E. sakazakii was used by hot water at

70℃ or greater and microwave heating for 90 sec or longer. Reconstituted PIF and sunsik were inoculated with cocktailed

vegetative cells of E. sakazakii at 2 to 3 log CFU/mL to investigate the growth curve of this organism and stored

at 5, 10, 15, 20, 25, 30 and 35℃. Viable counts slightly changed at 5, 10℃ during 48 h but grew at 15℃ or greater.

Considering that E. sakazakii is able to grow in infant formula milk at refrigerator temperature, reconstituted PIF and

sunsik that are not immediately consumed should be discarded or stored at refrigeration temperatures within 24 h.
