Which statement best describes disinfectants that are EPA registered and broad-spectrum?

• A. They kill only bacteria.
• B. They can kill both bacteria and viruses when labeled as broad-spectrum.
• C. They kill fungi only.
• D. They are not suitable for salon use.

Answer: (B)

A disinfectant that is EPA registered and broad-spectrum is meant to cover a wide range of microbes. When a product is labeled broad-spectrum, it indicates effectiveness against multiple categories of pathogens, and the label will specify exactly which organisms it kills. If the label lists bacteria and viruses, that means the product can disinfect surfaces against both groups, provided you follow the stated contact time and usage instructions. This is why that statement is the best: it reflects the practical meaning of broad-spectrum in the EPA-registered context. Choices that focus on only one type, like bacteria or fungi, don’t match the idea of broad-spectrum. And a claim of not suitable for salon use would contradict the typical purpose of EPA-registered disinfectants designed for salon environments—these products are chosen because they’re approved for such settings when the label permits it. Always check the label to confirm which microorganisms are killed and the proper use requirements.
