What is Pest Risk Analysis for? To convince decision makers that regulation of a pest is justified (or not); To give them guidance on suitable, proportionate, Phytosanitary Measures; It is not easy to do. Risk assessment better done; Insufficient on risk management. This is an overview of recent European experience.

European experience PRA developed over many years, Necessary because: Speed of trade movement; Large increase in bulk imports of planting material; Too many pests establishing which had not been serious in endemic areas – For example Essigs lupin aphid (Macrosiphum albifrons) Western flower thrips (Frankliniella occidentalis) Silver leaf whitefly (Bemisia tabaci)

Other drivers for change Government role for Crop protection changed; Agreement on initiation of PRA for interceptions; WTO-SPS agreement of 1994; The development of EC Single Market

EC legislation Introduced 1976 – harmonised standards, Member States own import regulations; 1993 Single Market – harmonised import regime; no internal frontiers; movement with plant passports.

Structure of EC legislation In primary legislation Articles – main legislation on a Plant Quarantine system; Annexes – the Phytosanitary Measures. In secondary legislation Implementing Directives; Derogations.

EPPOs role in PRA Specialist Panels may develop PRA; Phytosanitary Measures Panel harmonises these; Approved by the Phytosanitary Regulations Working Party and EPPO Council Standardised implementation PR Assessment scheme (EPPO, 1997 & EPPO, 2002); More recently PR Management scheme been developed; Forces consideration of each potential pathway (EPPO, 2001). From 2006 a newly established Panel will conduct PRAs (as Suffert & Petter Monday). Action List Member Governments consider for regulation.

EC regulations EC is smaller, less diverse than EPPO; The European Commission considers the EPPO recommendations + EC specific evidence; Proposes pest listing and accompanying phytosanitary measures to the SCPH. European Food Standards Agency (EFSA) role in considering the recommendations of the PRA to be developed.

How is this done in the EU? Working Groups of experts assist the European Commission to develop proposals for regulation; This includes selection of recommendations for phytosanitary measures; Then report their recommendations to SCPH, the decision makers; Following revision in plenary sessions, a regulation may be agreed and adopted.

Emerging processes in the EC EC Annexes Working Group Since 2003, an EC Annexes Working Group of experts has been examining proposals for pest specific regulation; examine recommendations from EPPO and other Member States; a single WG means there will be greater uniformity of evaluation of the proposals; difficulties, requires experts that have considerable breadth of knowledge; all pest organisms from viroids to invasive plants considered; the risk to many diverse crops husbanded in different ways; different environments, both natural and man made.

Choice of Phytosanitary Measures Consider many different possible measures; required for all imports and may also be required for movements within the EC (controlled by the plant passport) ;

Choice of Phytosanitary Measures selection of measures determined by statutory requirements, custom and practice; Prohibition and post-entry quarantine not usually acceptable; Treatments not to restrict what may be used: recognition that pesticide registrations differ worldwide and facilities for physical treatments are not universally available. Recognise smallest justified pest free export areas for the organism; Exceptionally area freedoms only recognised by surveillance according to EC legislation.

How to deliver to the Standing Committee on Plant Health? Considerable, diverse information gathered from different sources and evaluated; Must be made available to the SCPH; An outline electronic proforma has been devised to facilitate this; Annexes Working Group Recommendations; the Annexes Working Group Recommendations; Attaches supporting documentation: eases the work of the SCPH; also provides a transparent justification for the proposals.

Annexes Working Group Recommendations The Proforma Part 1 Harmful organism name [with Bayer code if known & details of taxonomic position] ; Present regulatory status in the EC legislation; Information on Harmful organism, hosts & present pest status in the European Union;

Annexes Working Group Recommendations The Proforma Part 2 The Working Group recommends that the Standing Committee on Plant Health should consider amending the relevant Annexes to the Directive 2000/29/EC as follows: [recommendation inserted] Recommendation for listing – Annex I or Annex II; Recommendation for Phytosanitary Measures – Annex IV A I, IV A II or IVB; Recommendations for requirements for Phytosanitary Certificates and / or plant passports Annexes VA and VB; Explanation of Recommendation

Annexes Working Group Recommendations The Proforma Part 3 Justifying supporting documentation. Quarantine pests for Europe (1997) Data sheet. Pest Risk assessment – EPPO or other Report of a Pest Risk Assessment – EPPO or other Pest Risk Management and or Pest Specific Phytosanitary Regulations – EPPO Report of a PRM/PSPR EPPO published Diagnostic protocol EPPO Phytosanitary Procedures EPPO Alert Report of discussions at Annexes Working Groups Report of discussions at EPPO or other meetings. Others – letters, legislation etc.

Progress New, and evolving process; In late 2004 first recommendations prepared for submission to the SCPH; 22 recommendations presented at the March and April 2005 committees;

Recommendations u Aonidiella citrina u Apple proliferation mycoplasm u Cacopsylla fulguralis u Chrysanthemum Stem Necrosis Virus u Ciborinia camelliae u Dendrolimus sibiricus u Diabrotica virgifera u D. v. virgifera u D. v. zeae u Dryocosmus kuriphilus u Fusarium foetens u Impatiens necrotic spot virus u Leveillula taurica u Monilinia fructicola u Parasaissetia nigra u Paysandisia archon u Rhynchophorus ferrugineus u Rhynchophorus palmarum u Scrobipalpopsis (Tecia) solanivora u Stegophora ulmea u Thrips australis u Xanthomonas axonopodis pv. Dieffenbachiae

Progress The recommendations varied. For example:- simple, that no regulation was justified; to transfer the pest between annexes (as recognition pest now established in part of the EU) with additional Measures certified by plant passports; New listings with additional phytosanitary certificates and associated measures required. Now with the European Commission and the first proposals are emerging for SCPH

Recording uncertainty Developing this process has highlighted some difficulties with using information, recommendations and ISPMs; Especially ensuring the risk management options are appropriate and proportionate; Important to ensure that data sheets and risk assessments record: when there is a lack of information or when it is known that something does not happen. The EPPO PRA scheme emphasises the first and indicate when further research is needed;

Risk Managers needs – known unknowns and known nos! Guidance when negative information is known; Pathway analysis is the key to selecting Phytosanitary Measures; When a pathway cannot or does not exist, this must be recorded. NOT goes without saying For example, that the fruit of a virus infected plant may never be infected. an organism may not be truly seed-borne but, can it contaminate a seed? If omitted an uncertainty may result in recommending unsuitable Measures.

Risk Managers needs – Economic evaluation - crop husbandry Also required in the assessment report is an evaluation of the husbandry of crops; Can be relatively straightforward:

Tomato evaluation an important crop throughout the EU; crop area and value is recorded; tomato pests unlikely to have environmental consequences; BUT risks and cost-benefit analysis different between; outdoor grown; lightly protected crops of the south; glasshouse, heated, crops of the north. Pepino mosaic virus Liriomyza huidobrensis

Maize (Zea mays) evaluation More complex example. very different values and uses in Europe. when used for animal feed, may be fed whole cob; whole plants finely chopped; off cob as grain maize; or as direct pasture feed. for human consumption may be off or on the cob; with very strictly controlled inputs for baby food. also planting and harvesting times vary - this affects the biology, and thus the risk, of most pest organisms.

Tree evaluation Evaluation more complex when plant has both amenity and environmental uses, For example trees.

Horse chestnut (Aesculus hippocastanum) an amenity tree, an amenity tree, of considerable benefit in streets and parks. of considerable benefit in streets and parks.

Sweet chestnut (Castanea spp.) timber, coppice, fruit bearing, amenity.

Other consideration for the Risk Manager Considerable variation in economic, environmental and social risks may occur throughout 25 Member states A key challenge in developing PRAs valid for the whole EU. These examples all illustrate the difficulties of conducting PRA for an enlarging EU, as discussed by Baker (on Tuesday).

Completing the Loop In Europe has been recognised that these experiences are fed back into the Risk Analysis process; Therefore the development of the EPPO Risk Assessment and Risk Management procedures is dynamic (as explained by Muriel Suffert on Monday).

Finalising the decision Completion of a report on the PR Analysis is not finalisation. A formal consultation process about the PRA which actively involves advisors, growers and administrators is then invoked; Before new regulations agreed an analysis of costs and benefits presented as a regulatory impact assessment. When impact high, RIA can be detailed with several scenarios to be evaluated (MacLeod on Tuesday). If cost of measures to government, importers or exporters, disproportionate to the risk, then SCPH can ask whether a less demanding Phyto measure will provide adequate safeguarding.

Final difficulties Broadening of consultation hampered by need for swift introduction of justified regulations and the diminishing number of specialists available to provide the independent analysis that recommendations demand. Introduction of specialised and practical ISPMs may help, but only if they permit sufficient flexibility of implementation and they address the priority organisms.

Regulated Non-Quarantine Pests Not considered in this paper; Have begun consideration by both EPPO and the EC; Actively gathering information on Regulated pests already present in EU; Not hide that linkage to PfP is causing considerable difficulties.

EC Legislation Development & introduction of legislation is a transparent process; Follows the WTO-SPS procedures; Also new regulations, minutes of the SCPH and legislation all available via the Internet. en.htm. en.htm

Conclusions A work in progress; The process both within EPPO and at EC SCPH evolves; Number of organisms already in-train is daunting; EPPO has either:- approved for the Action list; on the Alert List; or at in-between stages. Others in EC: limited derogations; subjects of new emergency action.
