<i>Listeria monocytogenes</i>in retail establishments: Contamination routes and control strategies

Abstract

In the past two decades, serious outbreaks of foodborne disease were caused by Listeria monocytogenes, a pathogen frequently found in delicatessens at retail. Although the prevalence of listeriosis is not high, the severity of disease is significant, with high hospitalization and mortality rates. Potential sources of L. monocytogenes and food contamination routes in retail and food service operations include incoming raw materials, food products, food handlers, customers, vendors, and environmental sources. Risk mitigation strategies for L. monocytogenes should be based on integrated control along the food chain continuum, from farm to retail establishment.
