Risk Ranger

Risk assessment is a crucial aspect of running a successful, safe food business. The risk assessment process involves methodically describing a food production system and identifying possible points of failure that could give rise to hazards.

An important objective of risk assessment is to provide information that will help the food manufacturer determine whether a pathogen is, or could be a significant hazard in their food production system and how best to prevent the hazard being realised.

Risk Ranger is a simple food safety risk calculation tool intended as an aid to determining relative risks from different product, pathogen and processing combinations. Risk Ranger provides a simple and quick means to develop a first estimate of relative risk. It is a generic but robust model that uses information about all elements of food safety to make risk calculations.

In addition to ranking risks, Risk Ranger helps to focus the attention of the users on the interplay of factors that contribute to foodborne disease. The model can be used to explore the effect of different risk-reduction strategies, or the extent of change required to bring about a desired reduction in risk.

The model can be used by risk managers and others without extensive experience in risk modelling. It is a useful tool for helping to train food safety managers to think in terms of risk.

The user is required to answer 11 questions related to the severity of the hazard, likelihood of a disease-causing dose of the hazard being present in a meal and the probability of exposure to the hazard.

Full details of the tool and its uses and limitations can be found in the International Journal of Food Microbiology, 77:39-53, 2002.
