2004 MAR 4 - (NewsRx.com & NewsRx.net) -- Enterobacter sakazakii in rehydrated infant formula can be thermally inactivated.
"The presence of low levels of Enterobacter sakazakii in dried infant formula have been linked to outbreaks of meningitis, septicemia, and necrotizing enterocolitis in neonates, particularly those who are premature or immunocompromised. In the current study, the ability of 12 strains of E. sakazakii to survive heating in rehydrated infant formula was determined at 58 degrees C with a submerged coil apparatus," scientists in the United States report.
"The observed D58-values ranged from 30.5 to 591.9 s, with the strains appearing to fall into two distinct heat resistance phenotypes," said Sharon G. Edelson-Mammel and Robert L. Buchanan at the Food and Drug Administration. "The z-value of the most heat-resistant strain was 5.6 degrees C. When dried infant formula containing this strain was rehydrated with water pre-equilibrated to various temperatures, a more than four-log reduction in E. sakazakii levels was achieved by preparing the formula with water at 70 degrees C or greater."
Edelson-Mammel and Buchanan published their study in the Journal of Food Protection (Thermal inactivation of Enterobacter sakazakii in rehydrated infant formula. J Food Protect, 2004;67(1):60-63).
