B. Tuberculosis (Tb) control
Control of Tb (M. bovis) over the agricultural industry is managed by the Animal Health Board, whose primary objective is to manage Tb to
reduce the number of infected herds and to prevent Tb vector free areas becoming vector risk areas. The status of a vector area is determined
by the prevalence of wild animals (e.g., possums and ferrets) that are considered a source of infection.
