Which practice helps prevent cross-contamination in school food activities?

• A. Use the same cutting board for everything
• B. Separate cutting boards
• C. Rinse utensils quickly with water
• D. Wash hands only after cooking

Answer: (B)

Separating cutting boards prevents cross-contamination by keeping raw foods, which can harbor bacteria, away from ready-to-eat or minimally processed items. In school food activities, using the same surface for different foods can transfer germs from raw meat, poultry, or seafood to fruits, vegetables, or foods that won’t be cooked further. Having a dedicated board for raw proteins and another for produce reduces the chance of this transfer, especially when boards are cleaned and sanitized between uses or color-coded to distinguish them. Rinsing utensils quickly with water isn’t enough because bacteria can hide in surfaces and cracks and water alone won’t reliably remove them. Proper cleaning with soap and water, followed by sanitizing, is needed. Washing hands only after cooking misses critical moments to prevent contamination—hands should be washed before handling food and after touching raw foods or dirty surfaces to keep germs from moving onto food.
