Which option represents proper practice to prevent cross-contamination in food handling?

• A. Temperature abuse
• B. Sharing utensils without cleaning
• C. Using the same cutting board for raw meat and produce without washing
• D. Proper handwashing and sanitizing

Answer: (D)

Cross-contamination happens when pathogens are transferred from one surface or food to another, so interrupting that transfer is the key. Proper handwashing and sanitizing is the most effective way to stop the spread because hands are a major route by which germs move to ready-to-eat foods, utensils, and surfaces. Washing with soap and water for about 20 seconds removes dirt and many microbes, and using a sanitizer afterward helps reduce any remaining organisms, especially when a full wash isn’t possible.

The other practices would increase the risk of transfer. Temperature abuse focuses on allowing microbes to grow rather than preventing their spread between foods or surfaces. Sharing utensils without cleaning can move germs from one item to another, and using the same cutting board for raw meat and produce without washing directly transfers bacteria. Keeping hands clean and surfaces clean with proper sanitation minimizes these transfer paths, making it the best approach.
