Web-based PRRS Risk Assessment

The American Association of Swine Veterinarians (AASV) Production Animal Disease Risk Assessment Program (PADRAP) was initiated in 2006.  Iowa State University College of Veterinary Medicine, Food Supply Veterinary Medicine provides program coordination to develop, manage and promote disease risk assessment tools and databases of completed risk assessments held by AASV. 

What is PADRAP?

Production Animal Disease Risk Assessment Program (PADRAP) is an epidemiologically-based initiative to help producers and veterinarians manage disease risks faced by North American swine industry.  It offers a set of risk assessment surveys and reports for measuring and benchmarking disease risks.  There are currently two risk assessments available within PADRAP:

  • PRRS Risk Assessment for the Breeding Herd
  • PRRS Risk Assessment for Growing Pig Herd


Some of the ways PADRAP has been applied:

  • As a tool to evaluate current biosecurity protocols and/or to develop new biosecurity protocols to avoid risk
  • To demonstrate improvement in biosecurity over time to help justify expenditures of resources on measures to improve biosecurity
  • As an aid in the decision to initiate a project to eliminate PRRS virus from a site
  • As an aid in the decision to use a breeding herd site to produce genetic animals
  • As part of the due diligence process for purchases or contracting agreements
  • As a tool for regional elimination or control projects

Results – Benchmarking Reports

PADRAP Online allows trained veterinarians to submit assessments for sites and immediately view and print benchmarking reports. 

An example of a Risk Quadrant Report is shown below.  Each dot on the Risk Quadrant Report is the average internal (bio-management of virus already present) and external risk (bio-exclusion of virus not present) index scores for a given site.  The red dots represent the production system of interest and blue dots represent the most current survey for all other sites assessed in the database.
