PFGE as a tool to track Listeria monocytogenes in food processing facilities: Case studies

Abstract

The use of PFGE to track Listeria monocytogenes strains from the food processing environment to the food is explained in this chapter through two case studies. This illustrates the usefulness of this method to identify putative routes of contamination and persistent strains and to help in the implementation of corrective actions in food processing facilities to control the occurrence of this pathogenic bacterium.
