Survival and growth of Enterobacter sakazakii in infant cereal as affected by composition, reconstitution liquid, and storage temperature.

摘要: Invasive infections caused by Enterobacter sakazakii have occurred predominantly in low-birth-weight neonates and infants younger than 2 months of age. However, also healthy up to 8 age immunocompromised children 4 years The ability E. survive grow infant cereals as affected composition the cereal, reconstitution liquid, temperature is unknown. A study was done determine survival growth characteristics initially at populations 0.005 0.52 CFU/ml rice oatmeal or with mixed fruit cereal reconstituted water, milk, apple juice. Reconstituted were stored 4, 12, 21, 30 degrees C, monitored for 72 h. Growth did not occur C juice 12 C. Populations (> =1 CFU/ml) detected water milk degres 24, 8, h, respectively. markedly affect cereals. decreased increases mesophilic aerobic microflora 9 log CFU/ml, which concurrent decreases pH. sakazakii, 2.62 (pH 4.32), survived 40C least 14 days. pathogen grew 21 within days then undetectable levels (<1 CFU/10 ml) 5 30'C Initially, 7.32 50 It recommended that be discarded h after preparation -40C, temperatures will grow.
