Abstract
This standard is based on ISPM No. 11, «Pest risk analysis for quarantine pests, including an analysis of environmental risks and risks posed by living modified organisms». It provides detailed instructions for the following stages of pest risk analysis (PRA) for quarantine pests: preparatory stage, pest categorization, assessment of the likelihood of introduction, assessment of potential economic consequences and assessment of pest risk management. It contains a framework, based on successive questions, to decide whether an organism has the characteristics of a quarantine pest and to determine, if necessary, possible management options.
Highlights
The EPPO Quarantine Pest Decision Scheme is intended to be used in assessing the potential significance of a particular pest in relation to a clearly defined area (PRA area)
It may be necessary to have discussions with exporters about what measures are possible in practice, with importers to find out what measures might be cost-effective, with government representatives on the implications for international trade, and with plant protection experts to make a decision. about what control measures are available, how effective they are and to what extent it is possible to eliminate outbreaks [6, 7]
Where relevant information is not available on the pest in question, information on related organisms may be useful. If such indirect information is used in the assessment, this should be reflected in the assessment process and taken into account when making the final decision [4, 5, 8]
Summary
The EPPO Quarantine Pest Decision Scheme is intended to be used in assessing the potential significance of a particular pest in relation to a clearly defined area (PRA area). The scoring scheme in section A is presented according to the principle of a qualifying table, made up of consecutive questions with two alternative answers Where relevant information is not available on the pest in question, information on related organisms may be useful If such indirect information is used in the assessment, this should be reflected in the assessment process and taken into account when making the final decision [4, 5, 8]. For possible future reassessments of the PRA, it is important that all steps in the procedure are fully documented, indicating who carried out the assessment, how each decision was made and what information it is based on.
