(Seed Health Management for Better Productivity)- The pests which are likely to follow the pathway (e.g. be carried by the commodity) arethen listed, and each is then subjected to Stage 2 in the PRA process. If no potentialquarantine pests are identified as likely to follow the pathway, the PRA stops at this point.2. PRA Initiated by a PestA requirement for a new or revised PRA originating from a specific pest will mostfrequently arise in the following situations:- An emergency arises on discovery of an established infestation or an outbreak of a newpest within a PRA area.- An emergency arises on interception of a new pest on an imported commodity.- A new pest risk is identified by scientific research.- A pest is introduced into a new area other than the PRA area.- A pest is reported to be more damaging in a new area other than the PRA area itself, thanin its area of origin.- Audits reveal that a particular pest is repeatedly intercepted.3. PRA initiated by the review or revision of a policyA requirement for a new or revised PRA originating from policy concerns will mostfrequently arise in the following situations:- A national decision is taken to review phytosanitary regulations, requirements or operations- A proposal made by another country or by an international organization (RPPO, FAO) isreviewed- A new treatment or loss of a treatment system, a new process, or new information impactson an earlier decision- A dispute arises on phytosanitary measures- The phytosanitary situation in a country changes, a new country is created, or politicalboundaries have changed.The specific pest identified is then subjected to Stage 2 in the PRA process.Phase 2. : Pest Risk AssessmentAfter Stage 1, a pest, or list of pests (in the case of initiation by a pathway),are identifiedwhich are to be subjected to risk assessment. Stage 2 considers these pests individually (seeFigure 2). It examines, for each, whether the criteria for quarantine pest status are satisfied or not:Quarantine pests- "a pest of potential economic importance to the area endangered therebyand not yet present there, or present but not widely distributed and beingofficially controlled".In this context, "area" should be "an officially defined country, part of a country, or all or partof several countries", and "endangered area" should be "an area where ecological factorsfavour the establishment of a pest whose presence in the area will result in economicallyimportant loss".- 196 -
