Transcript

  • 1. Secure Pork Supply (SPS) Plan James Roth, DVM, PhD, DACVM Center for Food Security and Public Health Iowa State University College of Veterinary Medicine jaroth@iastate.edu
  • 2. North American Animal Agriculture Industry is Unique in the World• The size, structure, efficiency, and extensive movement inherent in the U.S. and North American livestock industries will present unprecedented challenges in the event of a Foot and Mouth Disease (FMD) or other Foreign Animal Disease (FAD) outbreak.
  • 3. USDA Foot and Mouth Disease Response Plan• FMD Detected in the US – 0 to 24 hours: • 24 hour standstill order for relevant zones and regions – 24 to 48 hours: • Institute continuity of business plans – Secure Milk Supply – Secure Pork Supply 3
  • 4. Foreign Animal Disease (FAD) Outbreak• Stop movement will quickly lead to overcrowding conditions with serious animal welfare and health issues. Center for Food Security and Public Health, Iowa State University, 2011
  • 5. Goals of an FMD ResponseThe goals of an FMD response are to(1) detect, control, and contain FMD in animals as quickly as possible;(2) eradicate FMD using strategies that seek to stabilize animalagriculture, the food supply, the economy, and protect public health; and(3) provide science- and risk-based approaches and systems to facilitatecontinuity of business for non-infected animals and non-contaminatedanimal products.Achieving these three goals will allow individual livestock facilities, States,Tribes, regions, and industries to resume normal production as quickly aspossible. They will also allow the United States to regain FMD-free statuswithout the response effort causing more disruption and damage than thedisease outbreak itself. 5
  • 6. Secure Pork Supply Plan (Funded by USDA APHIS VS)• Develop procedures to allow the safe movement of animals with no evidence of infection in a FAD control zone to a pork processing plant or to other sites to Ramirez accommodate different stages of production. Center for Food Security and Public Health, Iowa State University, 2011
  • 7. SPS Partners• SPS Advisory Committee – Federal and State officials – representatives of all phases of the swine industry – NPB, NPPC, AASV – swine disease experts – swine production experts – representatives of other interested commodity groups (to be added) Center for Food Security and Public Health, Iowa State University, 2011
  • 8. Proposed Approach to SPS• Premises registration and animal ID• Biosecurity standards• Active and passive surveillance• OIE compartmentalization• USDA monitored premises• Voluntary program pre-outbreak Center for Food Security and Public Health, Iowa State University, 2011
  • 9. Secure Pork Supply Advisory Committee• First meeting October 11-12, 2011• Working Groups formed: – Biosecurity – Surveillance – Compartmentalization/Monitored Premises – Data Collection, Management, and Sharing – Risk Assessments – Plan for response to an FAD Outbreak Tomorrow – Communications Center for Food Security and Public Health, Iowa State University, 2011
  • 10. FADs included in SPS plan• foot and mouth disease – Swine, cattle, sheep, goats, deer• classical swine fever• swine vesicular disease• African swine fever Foot and Mouth Disease : 7 days post infection PIADC Center for Food Security and Public Health, Iowa State University, 2011
  • 11. Disease Transmission (FMD, CSF, ASF, SVD)• Not zoonotic• Direct contact and oral exposure are the most important routes of infection for swine (Pigs are relatively resistant to airborne infection by all 4 FADs)• Indirect contact (fomites) also can play a lessor role for transmission• Pigs exhale large concentrations of FMDV, cattle are susceptible to aerosolized virus Center for Food Security and Public Health, Iowa State University, 2011
  • 12. Vaccine• FMD and CSF – Vaccine will not be immediately available, or will be in short supply• ASF and SVD – No vaccine• Not a viable option for initial rapid control of Ramirez these FADs in a large FAD outbreak Center for Food Security and Public Health, Iowa State University, 2011
  • 13. Tools for Control of FAD• Stop Movement• Biosecurity• Stamping Out – Slaughter of all clinically affected and in- contact susceptible animals (within 24 hours or as soon as possible)• Trace back/Trace forward – 28 days prior to outbreak• Rapid Diagnostics• Vaccination (FMD and CSF) – Vaccinate to kill/Vaccinate to live
  • 14. Tools for Control of FAD in a Large Outbreak• Stop Movement• Biosecurity• Stamping Out – Slaughter of all clinically affected and in- contact susceptible animals (within 24 hours or as soon as possible)• Trace back/Trace forward – 28 days prior to outbreak• Rapid Diagnostics• Vaccination (FMD and CSF) – Vaccinate to kill/Vaccinate to live
  • 15. Biosecurity standards• Define ahead of an outbreak• Participating premises can be rapidly designated as Monitored Premises in the event of an outbreak. Center for Food Security and Public Health, Iowa State University, 2011
  • 16. Pre-Outbreak Surveillance?• Part of comprehensive swine surveillance?• Part of the “Got tonsils program”? Add testing for the other viruses?• Oral fluid sampling?• Other? Center for Food Security and Public Health, Iowa State University, 2011
  • 17. Testing during an Outbreak• Implemented prior to issuing permits for pigs to move to other premises or to slaughter. Center for Food Security and Public Health, Iowa State University, 2011
  • 18. Data Management• Real time data collection, management, and display software will be necessary prior to and during an outbreak. Center for Food Security and Public Health, Iowa State University, 2011
  • 19. Questions?
