Chemotherapy

Treatment with INH was used on a limited scale in the past. Its use is not recommended since treatment of food animals with drugs used in the treatment of human tuberculosis creates the problem of the presence of drug residues in meat, milk, and other consumable products, thus aiding the development of drug-resistant strains of pathogenic mycobacteria. Because of the potential for the development of drug resistance (FAO 2012), and the long period (4-12 months of daily dosing) needed for chemotherapy in livestock for BTB (Dean et al. 2008), its use is contraindicated from a public health perspective (Martin 1994).
