A workshop co-hosted by the University of Minnesota Swine Group and the Center for Animal Health and Food Safety (OIE collaborating center for capacity building).

Veterinarians are at the forefront of decision-making on animal health; making informed, evidence-based decisions often relies on an assessment of the risk that an adverse event will occur. Risk analysis is the process of identifying and analyzing potential issues that could negatively impact a farm, or the industry as a whole, creating a framework to estimate, prioritize, and mitigate those risks. While analysis of risk is a daily part of a swine veterinarian’s duties, affecting decisions to invest in biosecurity and health interventions, most veterinarians receive little to no training on how to systematically assess risk.

The purpose of this workshop is to review key concepts in risk analysis. The format of the workshop will be organized around “hands-on” case studies, where participants will gain practical experience with qualitative risk analysis through small group activities, discussion, and interaction with instructors. Given the increasing threat of ASF to the US swine industry, the workshop will focus on case studies about ASF in terms of a) risk of introduction to the US via contaminated feed ingredients, and b) risk analysis to support disease control strategies if ASF is already present in the country.
