Assessing the impact of biosecurity compliance on farmworker and livestock health within a one health modeling framework

Year: 2025

Type: article

Abstract: transmission dynamics, the model is validated, and key parameters values are estimated. Using the calibrated model, we examine infection transmission in dairy cattle and zoonotic spillover to farmworkers with a focus on five key biosecurity measures: (1) animal movement control and quarantine, (2) disease monitoring and reporting, (3) hygiene and disinfection, (4) feeding and watering practices, and (5) antimicrobial stewardship. Simulations reveal that compliance with biosecurity measures that reduce host-to-host transmission in the animal population has the highest impact on the reduction of infection both in animal and farmworker populations. Further ODE-SDE model analysis indicates that full compliance with the other biosecurity measures is insufficient to prevent outbreaks in a dairy farm. These results are consistent with the local and global sensitivity analyses of the model. The One Health modeling framework developed in this study can also be applied to other zoonotic diseases as a guiding tool for decision making and optimal resource allocation to reduce the likelihood of spillover.
