title: Sterilization of infant formula.
abstract: A survey of 237 pediatricians currently practicing in Connecticut revealed that 97 (41%) recommend routine sterilization of infant formula for a mean of 4.4 months. Eight bottles of proprietary formula were prepared in a controlled manner: four utilizing the "terminal heating method" of sterilization and four utilizing the "clean method" without sterilization. While the "terminal heating method" resulted in less bacterial contamination, three of the bottles prepared by the "clean method" had negative coliform counts and the other bottle had a minimal count. Ten bottles prepared without sterilization were randomly selected from mothers who had brought their infants for well-child care. With the exception of a small inoculum of enterotoxin-producing Staphylococcus aureus in one bottle, no enteropathogens were identified. The implications of this study for the routine preparation of infant formula are discussed.
