Food Safety Test: Cross-Contamination and Sanitation for High School Students

📚 Quick Study Guide

• 🦠 Cross-Contamination Definition: The transfer of harmful bacteria from one food or surface to another.
• 🌡️ Temperature Danger Zone: The temperature range (40°F - 140°F or 4°C - 60°C) in which bacteria grow most rapidly. Keep food out of this zone!
• 🧼 Proper Handwashing: Wash hands thoroughly with soap and water for at least 20 seconds, especially after handling raw meat, poultry, or eggs.
• 🔪 Cutting Boards: Use separate cutting boards for raw meats and ready-to-eat foods. Color-coded boards can help prevent cross-contamination.
• 🧽 Sanitizing Surfaces: Clean and sanitize all food contact surfaces regularly with a sanitizing solution (e.g., diluted bleach solution).
• 🧊 Food Storage: Store raw meats on the bottom shelf of the refrigerator to prevent juices from dripping onto other foods.
• 🍎 Wash Produce: Always wash fresh produce thoroughly under running water before consumption.
