What is cross-contamination?

Reviewed by Jordan Morley, Editorial Lead at 247SimpleTests. Written by the 247SimpleTests Editorial Team from the official source material cited on every question.

Correct answer

The transfer of infectious material from one surface, tool, or person to another

A Cleaning a tool twice
B Using a new tool
C Mixing two products
D The transfer of infectious material from one surface, tool, or person to another

Why this is the answer

Cross-contamination is the transfer of infectious material — such as bacteria, viruses, or fungi — from one surface, tool, or person to another. For example, using the same un-disinfected implement on two clients, or touching a clean tool with a contaminated glove, can spread infection. Preventing cross-contamination is central to salon safety: it requires disinfecting multi-use tools between clients, discarding single-use items, washing hands, and avoiding 'double-dipping' products. Recognizing when and how cross-contamination occurs is a key exam skill.
