Update on PEDV

Update on PED ResearchLisa Becton, DVM, MS, DACVPMDir. Swine Health Information & ResearchNational Pork Board PED Initial EventsPEDV was confirmed in the US on May 16th, 2013 by diagnostic tests at the USDA National Veterinary Services Laboratory (NVSL) in Ames, IAFound in multiple farms simultaneously and then additional farms diagnosed positive potentially from lateral spread

Coordinated effort by all key stakeholders to understand where PEDV was/is occurring and how to best manage it:United States Department of Agriculture (multiple divisions)State Animal Health Organization representatives (SAHO)National Pork Board (NPB)National Pork Producers Council (NPPC)American Association of Swine Veterinarians (AASV)

Current Status of PED PED continues to be a major health challenge for U.S. producers into 2014

Since it was first diagnosed in May of 2013, there have been a total of >4700 cases reported: CASE reports are different than SITE reports.28 states (VT just diagnosed first positive case)Data can be found at www.aasv.org

National Pork Board FocusResearch focus - New virus therefore needed research on PEDv and impact for US producers

Development and communication of producer information/resources

Containment/management strategiesWork with USDA/stakeholders and develop next steps for emerging disease response Rapid Response Team pilot/Surveillance activitiesPED Research Efforts

Development of Research Priorities*Swine Health Committee producers, veterinarians, advisors (university, government, industry)

PED Strategic Task Force

Input from AASV and NPPC membership

State Pork Associations inputPEDV Research PrioritiesInitial Research Priorities:Needed to get answers quickly! ($1,000,000 for PEDV research PEDV Research Funded for 2014For the Spring call for proposals, the Committee selected projects for funding focusing on: Validation of new diagnostic tests Continuation of a surveillance project to monitor incidence and track transmissionAssessment of efficacy of disinfectant to denature proteins and provide negative PCR result

Approximately $150,000 spent for 2014 so farPEDV Research For 2014The Board approved an additional $650,000 for use for PEDV research, communications and outreach for 2014

March 19th: Feed Consortium meeting in Iowa to discuss immediate needs for feed research; collaboration and $$ support by feed industry

Collaboration and $$ leverage with Genome Alberta $500K on research priority needs and focused RFP for PEDVPEDV Feed RFP 2014Conduct feed or feedstuff contamination risk assessments at all steps within the feed processing and delivery chain. Risk assessment should include potential role of vectors (i.e. birds) or fomites and development of best manufacturing and/or management practices to prevent feed contamination with PEDV/SdCV.

Demonstrate virus survivability in feed and feed ingredients to include the following variables: feed and feed components, storage time and temperature, processing procedure and time (meal or pellet), and moisture content. Conditions investigated should be representative of industry processes. To allow for the most efficient use of checkoff funds we encourage investigating other viruses important to the industry in the same study (i.e. PRRS, TGE, Rotavirus, etc.).

PEDV Feed RFP 2014Investigate effectiveness and cost of feed or feed ingredient treatments that could be used to mitigate viral survival. Develop a viral dose-infection curve showing viral dose by time and by temperature for both pelleted and milled feed.Develop diagnostic procedures for determining potential live virus contamination of feed or feedstuffs.

PEDV Feed RFP 2014Proposals due April 2nd, 2014

Swine Health Committee will review and select proposals April 4th, 2014.

Additional PEDV/SdCV ResearchSdCV assessment for research needsWorking with diagnostic labs on immediate needs for research: pathogenesis, diagnosis etc.

PEDV research RFP finalized to be posted April 15th with proposals due April 22nd.Working with Genome Alberta on priorities and funding resources

SummaryPEDV and SdCV are emerging diseases of swine that have proven to be very costly to producers

Cooperation and collaboration between all sectors of industry and government is a must

Need to continue to focus efforts for collaboration and cooperation on key research questions for disease management and control Thank you!
