Spatial Patterns of Highly Pathogenic Avian Influenza in Minnesota (2015, 2022-2024): What Has Changed?
In collaboration with the Minnesota Board of Animal Health (BAH) and the University of Minnesota Center for Animal Health and Food Safety (CAHFS), this session presents a practical spatial analysis of highly pathogenic avian influenza (HPAI) across Minnesota’s poultry sector. Minnesota is the nation’s top turkey producer and ranks No. 12 in overall poultry production nationally. During the 2015 outbreak, the largest domestic animal disease event in U.S. history, the state accounted for almost 20 percent of the roughly 50 million domestic poultry lost or depopulated. Those losses, along with subsequent waves of HPAI activity, motivate a focused, Minnesota specific approach to risk detection and response. Drawing on case data from 2015 and from 2022 through 2024, we integrate descriptive epidemiology with complementary space-time modeling to track how HPAI has moved across space and through time. The descriptive component uses weekly and monthly epidemic curves and county-level incidence to set the baseline narrative. The modeling component applies space-time cluster detection using USDA National Agricultural Statistics Service counts of poultry operations as the population at risk. We assess the sensitivity of results to different spatial and temporal window choices and show how clustering signatures evolve across outbreaks. The outcome is a coherent framework that turns complex surveillance data into operational insight. By combining clear epidemic summaries with rigorous space-time scans, this approach pinpoints where and when risk concentrates and shifts across waves.
Biosecurity and Preparedness in Diverse Swine Production Systems
Is the average small-scale swine producer prepared to prevent and respond to high-impact diseases on their farm? African Swine Fever (ASF) remains a significant global threat to domestic and wild swine populations, with far-reaching consequences for animal health, producer livelihoods, and national food security. Although ASF has not yet been detected in the United States, preparedness depends greatly on the awareness, confidence, and practical capacity of veterinarians. This is particularly important when supporting small-scale and niche swine producers who may have less structured biosecurity practices. For these producers, accessible education and support are essential to strengthening biosecurity and preventing the introduction of ASF and other high-consequence swine diseases. However, veterinarians may face barriers to providing this outreach, including limited time, resources, confidence discussing foreign animal disease risks, or uncertainty around available point-of-care diagnostic tools and reporting processes. This session will explore these intersecting needs and challenges, highlighting opportunities to improve veterinary readiness, communication strategies, and farm-level disease prevention efforts.
Foreign Animal Disease Response Through a One Health Lens: Evaluating Mental Health and Building Surveillance Preparedness in Minnesota
This session explores how lessons learned from veterinarians responding to African swine fever (ASF) outbreaks in the Philippines can inform Minnesota’s preparedness for foreign animal disease events. Using a One Health framework, we will examine the intersection of disease surveillance, response-related stress, and practitioner wellbeing. Attendees will gain insight into the mental health impacts faced by veterinarians during crisis response and discuss upcoming opportunities, such as continuing education (CE), to strengthen resilience and engagement in Minnesota’s surveillance network.
