Swine & U: Secure Pork Supply Plans Still Important

As African Swine Fever (ASF) spreads around the globe, pork industry and its partners all pulling together to prevent the entry of ASF into US pig herds. African Swine Fever is one of three Foreign Animal Diseases (FAD) that US livestock producers and partners are working to exclude from the United States; another is Foot and Mouth Disease (FMD), which would infect not just pigs, but cattle, sheep, goats, deer and bison. FMD was eradicated from the US in 1929. The third FAD being watched is Classical Swine Fever (CSF) which many of us know as Hog Cholera, a disease also eradicated in the US in 1978.

Across the country, plans are in place establishing emergency FAD preparedness in livestock. Currently, Secure Food Supply plans have been developed for milk, poultry, beef and pork. The purpose of the Secure Food Supply plan is to provide livestock producers with a workable continuity of business plan should an FAD occur.

In the event of an FAD outbreak, livestock movement would be restricted, and preparation for such a catastrophe is the best way to ensure that producers could continue to move animals off of the farm and move products to market.

The Secure Supply plan also prepares producers for cooperating with animal health officials in the event of an outbreak, and provides consumers with confidence that their meat, milk and egg supply is safe.

Recently in Minnesota, veterinarian Dr. John King has been appointed as the statewide Secure Food Supply plan coordinator. He is working with all food animal species to get the message to producers and assist with completion of Secure Food Supply plans on all farms.

In the swine world, state and federal officials, collaborating with the National Pork Board, industry and universities, have rolled out Secure Pork Supply information to swine producers. This year the COVID-19 pandemic has overshadowed work being done to prepare farms for a potential FAD outbreak, but work within the Emergency Disease Management Committee (EDMC) for Swine has continued. EDMC swine subcommittee meetings continue and a statewide FAD emergency plan is systematically being created.

Producers who have not yet put their SPS plan into place are encouraged to get information from the national website, or through the University of Minnesota’s Extension website at Extension swine educators Sarah Schieck Boelke and Diane DeWitte are also available to assist producers as they complete their farm’s SPS plan.

Traceability and Movement Management
It’s been proven that restricting movement of animals reduces the spread of disease, but that benefit has to be balanced with the costs of interrupting business. In addition, there is a real threat to animal welfare when they are kept in close proximity to diseased animals.

A farm connected to a validated national Premises Identification Number (PIN) is a key component in helping officials determine disease control areas and potential movement of animals.

Enhanced Biosecurity
Four important concepts have been identified to tighten up a producer’s biosecurity effort
  • Identify a biosecurity manager
  • Maintain detailed records
  • Draft a written, site-specific biosecurity plan and document the training
  • Create a premises map
Foreign Animal Disease Training, Response and Surveillance - Swine farm personnel must become familiar with the three most common swine foreign animal diseases, FMD, CSF, and ASF.

Please note: FMD, CSF, and ASF are not public health or food safety concerns. Meat will still be safe to eat.

However, these diseases are very contagious in swine, and each team member on the pig farm should be able to recognize clinical signs. Currently swine producers are asked to keep a daily observation record of their pigs, and doing so will help provide timely documentation in the event of a disease outbreak. If suspicious signs are observed, farm personnel will be asked to collect oral and nasal swab samples to submit for testing. Any suspicions about pig health should be reported to a veterinarian immediately.

Premises ID Number (PIN)
The national premises ID number (PIN) is a unique seven-character identifier assigned to a premises where pigs are produced, kept, or moved through. Each state’s Board of Animal Health manages the identification program and assigns the PIN for producers. National PINs are not specific only to swine; premises where any food animal is raised can have a PIN.

Today more than 96% of swine premises use the national PIN. The pork industry is striving to reach 100% adoption of PINs. Not only will accurate PINs on every pig farm provide pinpoint accuracy to reduce disease spread, but PIN use demonstrates a superior traceability system to the United States’ international trade partners.

PINs are a key component of the Pork Quality Assurance Plus (PQA+) site assessment, and many packers require a PQA+ site assessment as a condition of sale. Since January 2015, all sows and boars sold into the food chain must have an ear tag containing the farm’s PIN. PINs are also required by many major swine shows and exhibitions.

To obtain a PIN, producers can contact the Minnesota BOAH at or call 651-201-6816.

Validate the Correct PIN location

A team from University of Minnesota’s department of Veterinary Population Medicine took a close look at PIN information and found two types of accuracy problems.

  1. PINs linked to a site with incorrect address or longitude and latitude coordinates. The PIN must be connected to the actual physical address where the animals are located. For emergency response activities, the PIN must correspond to the animal location.
  2. One PIN for several geographically distinct sites. Producers with more than one farm or barns on several locations need to get a separate PIN for each site. In the case of a disease outbreak, if multiple barns/farms are connected to one PIN, all of the facilities would be designated as infected, even if only one actually was.

Next Step
Minnesota’s Board of Animal Health has developed a “next step” for producers who have completed their farm’s Secure Pork Supply plan. A checklist completed by their herd veterinarian can be submitted to the BAH. That information will further assist Minnesota’s animal health officers determine if a movement permit can be issued in the event of an FAD disease movement restriction. The checklist can be found on the BAH website.

As swine producers learn more daily regarding African Swine Fever’s movement in other parts of the world, they will continue to hear about the Secure Pork Supply plan. The SPS is voluntary; Countless hours and thought have gone into preparing the pig community for continuity of business in the event of a foreign animal disease outbreak.
