About the research project
With an increasing demand for fresh or less-processed foods, minimising food safety risks has become a unique challenge to food businesses and public health authorities. A food-borne pathogen, such as Listeria monocytogenes, poses a serious threat to public health. This is because it is ubiquitous in nature and can cause a potentially life-threatening disease called listeriosis. L. monocytogenes has also been identified as a cause of numerous outbreaks associated with a variety of foods especially ready-to-eat products. Accordingly, a number of control strategies have been adopted to minimise the food safety risks associated with this pathogen. These include implementing interventions for reducing L. monocytogenes prevalence and environmental monitoring programs, and stringently following good manufacturing practices and sanitation standard operation procedures.
Despite those control strategies being in place, the presence of L. monocytogenes in foods still occurs and typically leads to a food recall. In Australia, there has been an increasing trend in food recalls due to microbial contamination over the last decade. L. monocytogenes was also amongst the most common pathogens responsible for food recalls (72 of 201 recalls between 2012 and 2021). These recalls greatly reduce consumer trust and affect food businesses' profitability. Therefore, being able to assess and manage the risks of food products being recalled is critical to the success of business while protecting public's health.
The aim of this project is to develop a framework for modelling approach for assessing the risks of food recalls due to L. monocytogenes. Ready-to-eat products and leafy green vegetables will be used as a model product to develop that framework. The framework will then be used to develop a decision support tool that can be readily adopted by food businesses to manage better the risks of those products being recalled or modified to consider other food products.
