Cross-contamination refers to the transfer of contaminants from one surface or object to another.

• A. Cross-contamination
• B. Contamination risk
• C. Surface cleaning
• D. Decontamination

Answer: (A)

Cross-contamination describes the actual transfer of contaminants from one surface or object to another, which is exactly what the statement is defining. In a barber setup, this means germs or residues moved from a dirty surface, tool, or towel to a clean client or to a clean surface if proper hygiene steps aren’t followed. The other terms don’t fit the description: a contamination risk is just the possibility of contamination, not the transfer itself; surface cleaning is about removing contaminants from a surface; decontamination is the broader process of removing or neutralizing contaminants, not specifically the act of transferring them between surfaces. To prevent cross-contamination, maintain strict hand hygiene, use barriers, disinfect and sanitize surfaces between clients, and sterilize reusable tools or use disposable items when possible.
