The document describes plans for a Secure Pork Supply (SPS) program to allow safe movement of pigs during a foreign animal disease outbreak in the United States. It discusses developing standards for premises registration, biosecurity, surveillance, and disease monitoring to designate premises as uninfected and allow their continued operation. An advisory committee is coordinating efforts including biosecurity protocols, surveillance methods, and a response plan to maintain pork production during an outbreak of foot-and-mouth disease, classical swine fever, African swine fever, or swine vesicular disease. The program aims to minimize disruption through rapid disease control and continuity of business.

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

4. Foreign Animal Disease
(FAD) Outbreak
• Stop movement will quickly lead to
overcrowding conditions with serious
animal welfare and health issues.

5. Goals of an FMD Response
The 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 animal
agriculture, the food supply, the economy, and protect public health; and
(3) provide science- and risk-based approaches and systems to facilitate
continuity of business for non-infected animals and non-contaminated
animal products.
Achieving these three goals will allow individual livestock facilities, States,
Tribes, regions, and industries to resume normal production as quickly as
possible. They will also allow the United States to regain FMD-free status
without the response effort causing more disruption and damage than the
disease outbreak itself.

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

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

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.
