First Assessment of Weeks-to-Negative Processing Fluids in Breeding Herds after a Senecavirus A Outbreak

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.

In this week’s science page Guilherme Preis, Neal R Benjamin, Deborah Murray, Emily Byers Taylor, Samuel Copeland, Grant Allison and Cesar A Corzo share the results of a study looking at the number of weeks processing fluids remain SVA-positive after an SVA outbreak.

Wait and see? Biosecurity decision-making under disease risk – Part 2

In the previous science page, Gabriela Bucini, Scott C. Merrill, Eric M. Clark, and Julie M. Smith of the Social Ecological Gaming and Simulation Lab at the University of Vermont shared that the decisions made by the players in different scenarios of disease risk, risk communication strategies, and neighboring farm biosecurity implementation allowed us to identify three prominent behavioral groups. The risk tolerant players invested very little in biosecurity in contrast to risk averse players who invested consistently throughout the simulation to protect their farms. Our third category, risk opportunists, primarily invested in biosecurity during high risk scenarios but limited investments during rounds with lower chance of infection.

Wait and see? Biosecurity decision-making under disease risk – Part 1

This short science page offers insights on decision making where a wait-and-see attitude induces a delay in biosecurity investments and implementation, which creates instability and uncertainty in the industry’s ability and capacity to control disease. Written by Gabriela Bucini, Scott C. Merrill, Eric M. Clark, and Julie M. Smith of the Social Ecological Gaming and Simulation Lab, University of Vermont.
