The University of Minnesota College of Veterinary Medicine’s (CVM) Secure Food System (SFS) team collaborate with public and private partners to develop tactical biosecurity strategies to limit disease spread for specific animal movements based on risk-based science. The awarded work pursues these objectives:

- Assess the risk of animal movements and their agricultural products during an outbreak and translate the risk-based science into workable movement permit guidance;
- Develop tactical strategies to limit foreign animal disease (FAD) outbreak spread in integrated agriculture systems; and
- Conduct outreach on emergency preparedness and the SFS platform.
This is our Friday rubric: every week a new Science Page from the Bob Morrison’s Swine Health Monitoring Project. The previous editions of the science page are available on our website.
Today, Dr. Makau and collaborators from the University of Minnesota provide insights into the role that repeated animal movements between farms play in the risk for Lineage 1A PRRS virus disease occurrence.

- Animal movements from 496 farms from a dense pig production area in the US, between 2014-2017, were analyzed.
- Direct contact (through animal movements) and indirect contact with an L1A (Lineage 1A)-positive farm increased the likelihood of L1A occurrence, and occurrence of non-L1A PRRS virus one year prior decreased the likelihood of an L1A occurrence.
- Outbreak risk increased for farms that engaged in more outgoing shipments.
