The process within risk assessment, of estimating the probability of harm and the severity of impact of an identified hazard, including attendant uncertainty. The process of identifying, evaluating, selecting and implementing alternatives for mitigating risk. The open exchange of information and opinion, leading to a better understanding of risk and risk related decisions. Application of these methods is voluntary. The principles may be applied to trade or movement of plants, plant products or materials that may negatively effect plant health, between farm neighbours, between counties, provinces or countries.
Managers are responsible for overall pest risk analysis.
The task of risk assessment should not be limited to a few specialists. In some situations, it may be appropriate to conduct and formally document very detailed risk assessments, that require input from several technical experts. In other situations it may be appropriate for less technical staff to apply the basic principles, to conduct and briefly document less formal assessments. It can however, document and clarify the components of risks. Managers use the information provided by risk assessors and other sources, to complete the risk management and communication components of the analysis, and ultimately to make decisions.
