Infrastructure of animal farms: key constructional elements in terms of biosecurity based on experience from Germany

The infrastructural design of an animal farm can significantly motivate or discourage adopting biosecurity measures in the daily routines. Proper planning and collaboration between architects, farmers and veterinarians is critical in the prevention of serious biosecurity issues, possible financial and animal losses. The consistent use of a uniform nomenclature that encompasses both, construction-functional and veterinary-epidemiological terms is therefore essential. We developed a conceptual framework for key constructional elements in terms of biosecurity and characterize key concepts from both disciplines, architecture and veterinary epidemiology. From an epidemiological point of view, we focus on pathogens and vectors, and from a constructional perspective on biosecurity areas, barriers and locks. The central aspect of the framework is the capability of barriers and locks to prevent (uncontrolled) movement of vectors between different biosecurity areas, thus interrupting pathways of pathogen transmission. Concepts are abstracted and aggregated in such a way that they can be applied to any animal husbandry system, regardless of species or size, and independently of a particular disease. The aim is providing a common basis of terminology that facilitates cross-sectoral cooperation
