Education and Economic Factors Shape Clusters of Biosecurity Beliefs and Practices: Insights from an Exploratory Survey of Midwest U.S. Swine Producers

Abstract: Despite existing biosecurity frameworks, there is limited empirical evidence on how US swine producers' beliefs, behaviors, and risk perceptions influence enhanced biosecurity implementation. We conducted an online survey among US swine producers to understand their biosecurity beliefs, behaviors, and practices. We used descriptive, unsupervised machine learning, and Factor Analysis for Mixed Data (FAMD). Of fifty-four respondents, 48.1% reported implementing some biosecurity measures, and 72.2% valued having enhanced biosecurity protocols. Majority (53.7%) considered their veterinarian's biosecurity opinion most important, and 37% were not concerned about African swine fever. Almost all (90.7%) felt confident they could contain an outbreak on their farms. However, none practiced enhanced biosecurity. The cluster analysis identified four distinct producer profiles (K = 4). Cluster A had young, inexperienced producers operating breeding facilities, with moderate biosecurity adoption. Cluster B included young, small-farm producers with variable biosecurity practices and low mortality rates. Cluster C comprised farms with moderate experience, higher mortality rates, and the lowest biosecurity adoption. Cluster D was composed of older, experienced, educated producers with the highest biosecurity standards and lowest mortality rates. FAMD revealed clustering along human capital and resource availability dimensions. Regular biosecurity assessments, tailored recommendations, and training would improve biosecurity in the swine industry.
