Which type of disinfectant is not considered tuberculocidal?

Low-level disinfectants are not considered tuberculocidal because they are designed to kill most bacteria, some viruses, and fungi, but are ineffective against more resistant microorganisms, including Mycobacterium tuberculosis, the bacteria that causes tuberculosis. These disinfectants typically contain quaternary ammonium compounds and are more suitable for surfaces that have minimal risk of contamination with blood or body fluids.

In contrast, intermediate-level disinfectants can kill more resistant pathogens, including most tuberculous bacteria, and high-level disinfectants are effective against a broader spectrum of organisms, including bacterial spores. All-purpose disinfectants may vary in their efficacy depending on their specific formulation but should be evaluated for their ability to handle a range of microorganisms, including things like tuberculosis. Therefore, it is the low-level disinfectants that lack the tuberculocidal properties necessary for environments where the risk of exposure to tuberculosis is a concern.
