The use of quantitative risk assessment in HACCP

During the hazard analysis as part of the development of a HACCP-system, first the hazards (contaminants) have to be identified and then the risks have to be assessed. Often, this assessment is restricted to a qualitative analysis. By using elements of quantitative risk assessment (QRA) the hazard analysis can be transformed into a more meaningful managerial tool. In this way the effect of control measures can be quantified, so the occurrence of contaminants in the endproducts can be estimated. Also, the quantitative risk assessment is a tool to derive or validate control measures and critical limits at process steps (CCPs). The practical use of quantitative risk assessment is demonstrated by two examples: the risk of raw fermented sausages and the risk of a pressurized meat product. It can be concluded that quantitative risk assessment is a powerful combination of food microbiology, modelling and applied statistics. It is recommended as the input for managing food safety issues as an extension or validation of the HACCP-system. © 2001 Elsevier Science Ltd.
