Educational Objectives

Educational Aim:
The reader will have a better understanding of the implications of Listeria and its identification in food–borne outbreaks.

Editor's comments:
An outbreak of listeria responsible for the deaths of at least 180 people was traced to processed meats in March 2018. The foods carrying the Listeria monocytogenes bacteria are ready-to-eat staples of the South African lunchbox ie rolls of cold meat and sausages. With 727 confirmed cases at the time, the World Health Organization stated that it was the largest ever recorded outbreak of the disease. Hence it is significant to review the identification and isolation of the bacterium.

Educational Outcomes:
The reader will learn more about routine microbiological food testing which is necessary to prevent food contamination and outbreaks of food-borne illness as relates to Listeria Monocytogenes.
