Mycobacterium bovis, the bacterium that
causes bovine tuberculosis (TB), is very
resistant to destruction by disinfectants. Any
product that is used to disinfect surfaces
potentially contaminated with Mycobacterium
bovis must be labeled as “tuberculocidal” or
“effective against Mycobacterium tuberculosis”.
Use all disinfectants according to
manufacturer’s directions, and follow all
precautionary steps to assure worker safety.
Disinfectants are not cleaners, so remove all
organic material from the area before using
disinfectants. The ability of a disinfectant to destroy
TB can be affected by organic material, bacterial load,
type of surface,
concentration, and contact time. (Contact time is the
amount of time the disinfectant is in contact with the
surface to be disinfected.) In general, higher
disinfectant concentrations and/or increased contact
time will be required for areas contaminated with high
concentrations of bacteria, on rough or porous
surfaces, in cool temperatures (wintertime), and when
unable to remove all organic material.
