SPS Components

Plan Summary

In the event of a foreign animal disease (FAD) outbreak in the U.S., maintaining business continuity for the pork industry is critical for food security and animal health and well-being. The goal of the Secure Pork Supply (SPS) Plan is to provide a workable business continuity plan for pork premises with no evidence of the FAD infection and associated industries that is credible to Responsible Regulatory Officials. Having the SPS Plan in place prior to an FAD outbreak will enhance coordination and communication between all parties, speed up a successful FAD response, and support continuity of operations for pork producers and associated industries. In an actual outbreak, decisions will be made by Responsible Regulatory Officials based on the unique characteristics of each outbreak.

Secure Pork Supply Plan Summary


Existing biosecurity plans on hog production sites may offer protection against endemic diseases but heightened precautions are needed for foreign animal diseases (FADs). The enhanced biosecurity recommendations outlined in the checklist below are based on the known exposure routes for the three FADs of concern. This document emphasizes four concepts that all pork production sites must implement to help protect their animals from endemic diseases and to be prepared in the event of an FAD outbreak in the U.S.:

  1. A Biosecurity Manager,
  2. A written site-specific biosecurity plan,
  3. A defined Perimeter Buffer Area, and
  4. A defined Line of Separation.
This enhanced biosecurity checklist and the corresponding Information Manual for Enhanced Biosecurity can be used to develop a site-specific, written, enhanced biosecurity plan.

During an FAD outbreak, it is not possible to prove that an animal or herd is free of infection. It is only possible to establish that there is lack of evidence of infection. An animal can be infected with an FAD before it shows clinical signs or is positive by laboratory testing. The surveillance component of the SPS Plan recommends allowing animal movement during an outbreak through laboratory testing as well as animal observation. Pork producers in an FAD Control Area will need to implement a formalized process for daily herd observation, or “Active Observational Surveillance” (AOS) to document that there is no evidence of an FAD infection in their herd.

Clinical signs of an FAD in the herd will rapidly become apparent to anyone inspecting the herd, or receiving animals from the herd. AOS should be initiated on all premises in the Control Area at the beginning of the outbreak and conducted daily. Incident Command Officials may also inspect swine herds and/or request to review the daily log of AOS kept by the Herd Health Monitor who has been trained to look for clinical signs and correctly record their observations.

Incident Command Officials must make decisions to implement a standstill order at the beginning of a foreign animal disease (FAD) outbreak and on re-starting animal movement during the outbreak. Many factors influence the controlled movement decisions and need to be considered. Discussions are occurring with the goal of getting consensus on the optimal approach to managing animal movement in an FAD outbreak. However, in an actual outbreak, decisions will need to be made by the Federal and State Incident Command Officials based on the unique characteristics of each outbreak. The Incident Command Officials will simultaneously be making many other decisions as they set up the Incident Command Post, including controlling movement of milk, cattle, sheep, and goats, as well as inputs needed to enable producers to feed and care for their animals.
