Why must a salon-grade disinfectant be labeled tuberculocidal (effective against Mycobacterium tuberculosis)?
a.Because clients are routinely tested for TB at the salon
b.Because tuberculocidal products are exempt from EPA registration
c.Because TB is the only pathogen present in salons
d.Because TB-killing efficacy is a recognized benchmark indicating broad-spectrum potency against tough lipid-coated pathogens
Explanation
Mycobacterium tuberculosis has a waxy lipid cell wall that is hard to penetrate. A product that kills TB is considered an intermediate- to high-level disinfectant and a reliable indicator of broad-spectrum efficacy, which is why the BBC requires it on non-porous implements.
