This Brief focuses on Listeria monocytogenes, from isolation methods and characterization (including whole genome sequencing), to manipulation and control. Listeriosis, a foodborne disease caused by Listeria monocytogenes is a major concern for public health authorities. In addition, addressing issues relating to L. monocytogenes is a major economic burden on industry. Awareness of its ubiquitous nature and understanding its physiology and survival are important aspects of its control in the food processing environment and the reduction of the public health concern.
