ABSTRACT

This chapter describes the practices of diagnosing cattle with bovine tuberculosis (bTB) in England and Wales. It requires to successfully diagnosing bTB, their social origins and how they cross a borderland between opposing veterinary traditions. The chapter describes the practices involved in diagnosing bTB in New Zealand. Here a different borderland is described in which farmers came to directly shape the conduct of epidemiology, transforming it beyond its purely scientific origins. The chapter explains in biosecurity borderlands, the nature of animal disease is not fixed or unchanging. Certainly, in exploring the work of biosecurity, the chapter reveals the value of social science in contributing to an understanding of the work of biosecurity. It presents that disease management belongs to no one discipline, but its practices are constantly in the making, varying from place to place across a veterinary borderland.
