ADynamicSystemto Control the Entry of Non-Authorized Visitors and Detect Superspreader Farms in Strongly Interconnected Systems

This paper addresses the need for effective biosecurity due to disease challenges,the emergence and re-emergence of new pathogens, the growing pressure of antibiotic restrictions,and the welfare and sustainability of livestock farming. It introduces the Biorisk® External platform,a cloud-based visitor control system that enhances data management and biosecurity complianceprotocols. This system analyzes visitation patterns, revealing trends and categorizing visits by authorization and risk status. This network analysis also allows for the identification of ‘superspreader’farms that represent a high epidemiological risk. The results advocate for integrating technology intobiosecurity protocols to optimize standard operation procedures (SOPs) to improve animal healthand mitigate economic losses, highlighting the importance of data-driven decision-making in modernlivestock farming.
