Enterobacter sakazakii causes a range of infections that can be fatal or cause lifelong debilitation in newborns. Although the bacterium is widespread in the environment, it has been most linked to neonatal infections through the consumption of contaminated infant formula. Because the organism affects the youngest and most vulnerable group of our population, the issue has become a critical concern for the food industry. This volume brings together all recent findings and knowledge on this unique pathogen and addresses a wide range of issues, including taxonomy, detection and identification, virulence potential, monitoring and control during infant formula production, and regulatory issues.
