What is the transfer of pathogens from one surface to another called?

• A. Cross-contamination
• B. Cross-infection
• C. Direct contamination
• D. Airborne contamination

Answer: (A)

This concept deals with how germs move between surfaces in a kitchen or food-handling setting. The transfer of pathogens from one surface to another is known as cross-contamination. It explains why contamination can spread when a contaminated surface, utensil, or hand touches another surface or food, even if the second item wasn’t directly touched by the original source. For example, touching raw meat with a knife and then using the same knife on ready-to-eat produce can transfer pathogens that weren’t present on the produce initially.

Cross-infection, on the other hand, describes transmission of an infection from one person to another, not from surface to surface. Direct contamination would imply contamination of food by contact with a contaminated source, but the term emphasizes the movement between surfaces or objects. Airborne contamination involves pathogens traveling through the air, not via surface contact.
