Transcript

  • 1. PED – Lessons Learned? Paul Sundberg DVM, PhD, Dipl ACVPM VP Science and Technology National Pork Board
  • 2. Lessons We’re Learning (So Far) 1. Diagnostic lab data sharing ability for disease analysis 2. Premises Identification Number on VDL submission form and producer acceptance of sharing data for disease analysis 3. Biosecurity, biosecurity, biosecurity a. Packing plants b. All truck traffic on/off the production sites c. Animal transportation 4. Epidemiology and transmission 5. Immunity and environmental viral load a. Sow farm selective rebreaks and elimination 6. You can’t afford to be comfortable or complacent 7. Industry and Government roles and responsibilities 2
  • 3. National Pork Board Organization • PED Strategic Task Force – NPPC – AASV – NPB – USDA – VDL – SAHO – Producers – Practicing vets • Biosecurity Working Group • Biocontainment Working Group • Packer Biosecurity Working Group
  • 4. Diagnostic lab data sharing ability for disease analysis Premises Identification Number on VDL submission form and producer acceptance of sharing data for disease analysis
  • 5. Current Status of PEDV
  • 6. Current Status of PEDV
  • 7. Biosecurity, Biosecurity, Biosecurity
  • 8. The role of harvest plant lairage and transportation in propagating the initial stages of an outbreak of Porcine Epidemic Diarrhea Virus in the United States in 2013. James F. Lowe, DVM, MS Diplomate ABVP (Food Animal) Lowe Consulting Ltd. Department of Veterinary Clinical Medicine, University of Illinois
  • 9. What we learned 1. Trailers can become contaminated at packing plants but less than one clean trailer is contaminated for each contaminated trailer that arrives a the plant. 2. There is contact by EVERY driver with the plant lairage and that appears to be sufficient to allow for PEDV movement between trailers. 3. More contact between trailer and plant is associated with higher rates of PEDV spread
  • 10. 10 PED Transportation Guidelines
  • 11. 11 PEDV Manure Hauling Guidelines
  • 12. Epidemiology and Transmission
  • 13. • Air – low • Spread by humans – moderate • Vehicles or other equipment – moderate • Pig movements – negligible • Water – ‘not likely’ • Feed pellets – moderate • Bedding materials – low Illinois Rapid Response Team - Risks
  • 14. Ohio Rapid Response Team - Risks • Spread by workers – low • Vehicles or other equipment – low • AI or veterinary supplies – negligible • Pig movements – low • Feed ingredients / commercial meal mix – ‘not likely’ • Feed pellets – high • Water, air, shavings – negligible
  • 15. Feed Risk – What Do We Know? • PED is not a human health or food safety issue. • The disease is impacting farms of a variety of sizes and production types and needs to be prevented through a variety of biosecurity procedures. • PCR is an important tool to use in assessing contact with the virus • There are multiple methods of PED transmission including environmental, transportation, feed systems and other vectors.
  • 16. Feed Risk – What Do We Know? • Within processing feed ingredients and feed processing there is a time x temperature that should be effective in inactivating the virus • Post processing contamination can occur in different segments of the feed supply chain • Pork industry stakeholders, veterinarians, producers, nutritionists and feed processors, agreed to a disciplined research approach to attack PED
  • 17. Immunity and Environmental Viral Load
  • 18. PEDV Research Priorities • Basic characteristics and pathogenesis of PEDV • Development & validation of diagnostic tests (antigen and antibody) • Environmental stability on various surfaces and substrates and effectiveness of sanitation efforts • Epidemiology of the disease • Sow Immunity • Duration of immunity; Optimizing feedback protocols; Diagnostic tests to assess sow and piglet immunity to PEDV 18
  • 19. Other PED Resources Recommendations available for: – Exhibit Organizer Biosecurity – Exhibitor Biosecurity – Positive in Breeding Herd – Positive in Nursery/Grow-Finish – Line of Separation – Create Clean Crossing – Additional resources…
  • 20. You can’t afford to be comfortable or complacent Industry and Government Roles and Responsibilities
  • 21. Newly Identified Swine Viruses • Porcine Circovirus Type 2b (China) • PED • Porcine Kubovirus • Porcine Deltacoronavirus
  • 22. NPPC 2014 Forum Resolution • A listing of non-reportable swine diseases not in the United States • Responsibilities of the government, industry organizations, producers and the pork chain in surveillance and response • Coordinated strategies to respond to and contain or manage disease • Strategies for the efficient sharing of information deemed necessary containment / control • Strategies to strengthen the defense of the US pork industry
