What is cross-contamination and give a salon example?

• A. Wearing gloves during service.
• B. Using the same nail file on multiple clients without proper disinfection.
• C. Changing towels between clients.
• D. Wiping a workstation with a clean cloth after each client.

Answer: (B)

Cross-contamination happens when microbes move from one person or surface to another because an item wasn’t properly cleaned, disinfected, or sterilized between uses. In a salon, using the same nail file on multiple clients without disinfecting between uses is a clear example: the file can carry bacteria, fungi, or viruses from the first client and transfer them to the next client, risking infection.

Wearing gloves is a protective measure that helps prevent contamination when used correctly and changed between clients. Changing towels between clients and wiping a workstation with a clean cloth after each client are also infection-control practices that reduce the chance of spreading germs. The key idea is preventing the transfer of microbes by properly cleaning, disinfecting, or using disposable tools between clients.
