Pest Risk Analysis

        EPPO and Pest Risk Analysis


One of EPPO’s main priorities is to prevent the introduction of dangerous pests (bacteria, fungi, insects, plants, viruses…) from other parts of the world, and to limit their spread within the region should they be introduced. In recent years, trade networks have expanded and diversified, increasing the risks of introducing pests to new geographical areas. Measures adopted by countries to protect their territories from these introductions should be technically justified and an International Standard for Phytosanitary Measures (ISPM) on Pest Risk Analysis (ISPM no. 11) has been developed in the International Plant Protection Convention (IPPC) framework. Since the 1990s, the following developments have taken place within EPPO:

  • EPPO has developed a decision-support scheme for Pest Risk Analysis and a computer program (CAPRA) to assist pest risk analysts in running the decision-support scheme - read more >>
  • A Panel on PRA development has been created - read more >>
  • Expert Working Groups (EWGs) are now being convened to conduct PRAs on specific pests - read more >>


EPPO Standards and CAPRA 



PRAs conducted by EPPO Expert Working Groups

EWGSince 2006, EPPO organizes meetings of Experts Working Groups which are conducting PRAs on specific pests following the EPPO Decision-support scheme and its computerized version CAPRA (see above). The conclusions resulting from these PRAs are addressed to the EPPO member countries only (the area potentially at risk that is considered during these PRAs is the EPPO region, not the other parts of the world).

Other PRAs conducted in the EPPO framework

You can find here a list of PRAs which have been carried out or studied by different EPPO Panels (e.g. Panel on Phytosanitary Measures, Panel on Quarantine Pests for Forestry, Panel on Invasive Alien Plants). Most of these PRAs have been originally prepared by NPPOs of EPPO member countries or by the EPPO Secretariat. As for the PRAs carried out by specific EWGs (see above), all resulting documents (full or summary PRAs, reports of PRA and PRM, draft datasheets) are only addressed to the NPPOs of EPPO member countries.
