Which term describes a chemical agent that demonstrates bactericidal, germicidal, fungicidal, and limited virucidal activity and is registered with the EPA?

Which term describes a chemical agent that demonstrates bactericidal, germicidal, fungicidal, and limited virucidal activity and is registered with the EPA?

• A. High Level Disinfectant
• B. Intermediate Level Disinfectant
• C. Low Level Disinfectant
• D. Sterilant

Answer: (C)

Disinfectant classifications hinge on the range of organisms they can inactivate. A chemical that is bactericidal, fungicidal, and has limited virucidal activity can kill many bacteria and fungi and some viruses, but it does not reliably destroy resistant organisms like spores or certain mycobacteria. That narrower spectrum, combined with EPA registration that confirms its labeled uses and limitations, is what defines it as a low-level disinfectant. High-level disinfectants and sterilants, by contrast, offer broader virucidal activity and/or the ability to kill spores, with sterilants aiming to destroy all microorganisms. So the described agent fits the low-level disinfectant category because it covers bacteria, fungi, and limited viruses, without claiming sporicidal or tuberculocidal activity.
