Listeria monocytogenes is the causative agent of the human illness called listeriosis. The data reported in the last 15 years of scientific literature concerning the relationship between this microorganism and the catering sector showed a permanent presence of the opportunistic pathogen through the years, though with low frequencies.
Even though the pathogenic capacity of L. monocytogenes is practically circumscribed to a few risk categories as pregnant women, newborns and different kinds of immunocompromised people, given its high case-fatality rate this disease represents the second cause of death for foodborne infection in Europe.
As it emerged from the reviewed literature, L. monocytogenes was recovered in many different food categories, which testifies the widespread of the pathogen in the food chain. The main causes of L. monocytogenes presence were poor microbiological quality of raw materials, cross-contamination, inadequate cleaning practices, improper storage temperature, inadequate preparation processes, and a lack in the training of staff on food hygiene.
In particular, cross-contamination of foods can be reduced by hand washing, use of gloves, separation of raw materials from end products, sanitation and disinfection of equipment and food contact surfaces, hence, a structured training program of staff on these practices is essential.

Food safety training is utilized in the food industry to provide employees with the needed knowledge on how to prevent foodborne illnesses. However, although there is evidence that current food safety training is effective in increasing employee knowledge, employees’ observed behaviors often do not change and, therefore, the risk of foodborne illness is not decreased. In this review we discuss several motivational theories and propose a unique use of augmented reality for training to increase compliance of employees in regards to safe handling of foods.
