Food Safety Quiz: Chlorine, Quat, and Iodine Sanitizer Edition

🧪 Quick Study Guide

• 🌊 Chlorine: A widely used sanitizer. Effective at low concentrations. Concentration: 50-200 ppm. Contact Time: Minimum 7 seconds.
• 🌿 Quaternary Ammonium Compounds (Quat): Non-corrosive and stable. Effective against a broad range of microorganisms. Concentration: 200-400 ppm. Contact Time: Minimum 30 seconds.
• ⚗️ Iodine: Effective but can stain surfaces. Concentration: 12.5-25 ppm. Contact Time: Minimum 30 seconds.
• 🌡️ Factors Affecting Sanitizer Effectiveness: Concentration, temperature, contact time, and water hardness.
• ⚖️ Concentration Calculation: Use appropriate test kits to ensure accurate sanitizer concentration.
• 🕒 Importance of Contact Time: Sufficient contact time is crucial for effective sanitization.
