Interpretive summary: Listeria monocytogenes has been known as a human pathogen for over 80 years and causes over 1500 illnesses annually in the United States. Undercooked meat and meat products are commonly implicated as transmission vehicles in these outbreaks. We quantified a reduced heat treatment given to these foods to provide an adequate degree of protection against survival of the pathogen and developed a mathematical model for predicting the destruction of this pathogen in beef. The model can be used to predict the time required at any temperature to kill a certain number of bacteria. This information will be of immediate use to consumers and to the food industry and regulatory agencies to aid in the development of guidelines to ensure safety of the food supply.
