With the diagram for risk determination, it is determined if and how the hazard has to be controlled for food safety. ? For every hazard the chance (Likelihood) that the hazard occurs, is determined with the ‘chance determination table’ on the next page. ? The effect (severity) is determined (right line) with the ‘effect determination’ table. ? By multiplying the chance and the effect, the risk is quantified and the kind of control is determined. In this way, an understanding for level differences is developed, but quantifying risks is extremely difficult. ? If the risk is 9 or less, controlling with general control measures or preventions are enough (PRPs).
