Abstract
Survival and growth of Bacillus cereus group and presumptive Cronobacter in the rehydrated sunsikwere investigated to control the pathogens. Five sunsik contaminated naturally by the pathogens were rehydrated with hot waters of 50, 60, 65, and 70°C and kept for 24 hr at 5 and 25°C. Survival and growth of B. cereus seemed to be influenced not by rehydration water temperature, but by storage temperature and time after rehydration. However, survival and growth of Cronobacter was influenced by both rehydration temperature and storage conditions. Especially, storage temperature and time seemed to be more important than the rehydration temperature to limit the growth ofCronobacter. Therefore, it is required to take immediately the sunsik after rehydration with at least 65°C water, otherwise within 6 hr at room temperature for the risk reduction of B. cereus andCronobacter.
