PDF: Dr. Scott Dee - PRRS Eradication Update

  1. 1. Elimination of PRRSV from Minnesota: It’s the right time to move forward. Scott Dee Acknowledgement of funding and in- kind resources • USDA NRI PRRS CAP 1 and 2 • National Pork Board • MN Pork Board • MN Rapid Agricultural Response Fund • MN Veterinary Diagnostic Laboratory Genetiporc • Preserve International • Midwest Microtek 1
  2. 2. SDEC partners • Corporate members • Practice members – PIC – Pipestone Vet Clinic – Genetiporc – Fairmont Vet Clinic – Boehringer-Ingelheim – Swine Vet Center – Pfizer – Clinique Demeter – Novartis – Cannon Valley Vets – Noveko – Carthage Vet Service – Camfil Farr/Filtration Systems, Inc – Bayer – Japanese Association of Swine Veterinarians Disclosure • I do not – Receive royalties or commissions on the sales of filters or filtration equipment. – Hold any patents on filtration inventions. – Have research contracts or consulting agreements/retainers with filtration/equipment companies. – Use monetary contributions from filtration companies to conduct filtration-based research 2
  3. 3. Elimination of PRRSV from MN: It’s the right time to move forward • Unprecedented economic circumstances • Advancements in knowledge and technology • Strong support at the AASV and MN PETF level Veterinary perspective • AASV position statement on PRRS eradication • “Eradication of PRRS from the North American pig population is the long-term goal”. 3
  4. 4. The Minnesota PRRS Eradication Task Force (MN PETF) • Organized in 2005 • Mission: To develop and oversee the plan for PRRSV elimination in Minnesota • Proactive: To be ready to act when the time is right. Participants • Producers – Langhorst (Southern MN), Starner (Northern MN) – Leiopold (MPPA), Crawford (MPB), Preisler – Graff (MPB research) • Practitioners – Pipestone (Nerem), Swine Vet Center (Reicks, Loula), – Fairmont (Ruen), Cannon Valley Vets (Strobel) • UMN swine group and VDL – Davies, Dee, Morrison, Murtaugh, Rossow, Torremorell • MBAH – Thompson • NPB – Becton 4
  5. 5. MN PETF: Road Map to Success Goals Research Monitoring Application Communication Successes Initiate discussion Area Mapping Short Organize MN PETF Term Biosecurity years 1-5 Assessments Regional Projects Write materials Differential Raise awareness Medium Diagnostics Term Build teams years Demonstration Expansion of 3-15 Projects Communicate results Regional Projects Immune Measures Persistence Long Term Vaccine Establishment of years Development PRRS (+) and (–) 12-20 Regions Genetic Resistance It’s the right time to move forward. • PRRS is costly – $5-$15.00/pig – Competitive advantage globally • Humans and animals suffer – Emotional trauma – Mortality • Market-driven opportunities – Empty facilities – Need to reduce inventory 5
  6. 6. It’s the right time to move forward. • We know and understand a great deal more now than we did 3 years ago: – We know how to eliminate PRRSV from farms. • Herd closure, Depop-Repop – The mystery of area spread has been solved • We now understand the routes of PRRSV spread between farms – The virus can spread up to 6 miles in the air. • We now know how to reduce re-infection risk in swine-dense regions – Air filtration Air filtration • Experimental setting (SDEC facility) – 3 years: • no infection of filtered facilities • 42% infection rate in non-filtered facilities • Field setting – AI centers (SW MN/N IA) • 3+ years: no infection of filtered studs – Sow herds (S MN/ N IA) • 16 months: – 2/10 filtered farms infected » Personnel and transport breaches documented » No evidence of filter failure – 17/21 non-filtered farms infected 6
  7. 7. Other Breakthroughs • Oral fluid (rope) sampling – We may not have to bleed pigs anymore • Jeff Zimmerman • Mapping tools – “A picture is worth a 1000 words!” – Essential for regional projects • Peter Davies • PRRSV can be eliminated at the farm, regional and national levels – Stevens county • Bob Morrison 7
  8. 8. Stevens County 2004 Stevens County – Dec ‘09 8
  9. 9. 7 counties; Dec ‘09 N – 212; Dec ‘09 9
  10. 10. It’s the right time to move forward. • The industry is starting to agree that we need to do something! – People are tired of PRRS! • Too much has been lost. • No “PRV-like” vaccine technology on the horizon. • People need a mission. • It has to be a national program.. – Other states are starting regional projects. – Strong agreement at the NPB swine health committee level. – Veterinary support is building across the US. • Funding for regional projects is available (CAP 2). Why Minnesota? • We are in an ideal position to lead – Progressive producers and vets – Great relationship with UMN swine group – Best VDL in the world • Yes, there will be challenges and questions. – Animal movement? – Role of government? – Producer buy-in? 10
  11. 11. I Believe We Can: • Work together to develop a producer- driven, voluntary plan for eliminating PRRSV from Minnesota. • Provide an example for the nation to follow. • Turn a negative into a positive. An Example of MN Leadership • Resolution 10-01: PRRSV eradication – The MPPA recommends that policy be adopted by the NPPC with the end goal of eradicating PRRSV from the US swine herd. – The policy should include and identify appropriate government resources and investments for accomplishing this goal but the policy should not make eradicating PRRSV a government mandate. 11
  12. 12. MN Leadership. • Resolution 10-01: PRRSV eradication – The MPB recommends that the focus of addressing PRRS in MN and the US be eradication of the virus. – The MPB urges the NPB to prioritize research and education towards tools and techniques that can eradicate PRRS. Next steps • 1. Voluntary program – Continue the research – Communicate findings and experiences • 2. Expansion of area control and eradication projects. – Northern zone – Southern zone • 3. Building of teams. – Collaboration with other states • 4. Development of plan. – MN PETF 12
