Why Cleaning and Sanitizing is Important

In a food service operation, maintaining cleanliness is critical for ensuring food safety. Knives and cutting boards are used daily to prepare various foods, making them potential sources of cross-contamination if not properly cleaned and sanitized. By following the correct procedures, you can prevent foodborne illnesses and protect your customers’ health.

Steps for Cleaning and Sanitizing Knives

1. Rinse the Knife: Begin by rinsing the knife under warm running water to remove visible food debris.
2. Wash with Soap: Use a clean sponge or brush with hot, soapy water to scrub the blade and handle thoroughly. Pay extra attention to grooves or textured areas.
3. Rinse Again: Rinse the knife with warm water to remove all soap residue.
4. Sanitize: Submerge the knife in a sanitizing solution, such as a mixture of one tablespoon of unscented bleach per gallon of water. Let it soak for at least one minute.
5. Air Dry: Place the knife on a clean, sanitized surface to air dry. Do not use a towel, as it may harbor bacteria.

Steps for Cleaning and Sanitizing Cutting Boards

1. Scrape Off Debris: Use a scraper or spatula to remove leftover food particles.
2. Wash with Soap: Wash the cutting board with hot, soapy water using a clean brush or sponge. Be sure to scrub both sides, even if only one side was used.
3. Rinse Thoroughly: Rinse the cutting board with hot water to remove all soap.
4. Sanitize: Submerge the cutting board in a sanitizing solution. Alternatively, spray the solution evenly across the surface and let it sit for the recommended time.
5. Dry Completely: Allow the cutting board to air dry completely before storing it.

Best Practices to Prevent Contamination

• Use separate cutting boards for raw meat, poultry, and seafood to avoid cross-contamination.
• Inspect knives and cutting boards regularly for damage, such as cracks or chips, which can harbor bacteria.
• Replace heavily worn cutting boards and damaged knives promptly.
• Store cleaned knives in a designated knife rack and cutting boards in a sanitized area.

Common Mistakes to Avoid

• Skipping the sanitizing step. Cleaning alone does not kill bacteria.
• Using the same towel to dry multiple tools.
• Allowing knives or cutting boards to air dry in an unclean area.
• Using harsh cleaning chemicals not approved for food contact surfaces.

Conclusion

Properly cleaning and sanitizing knives and cutting boards is a simple yet crucial step in maintaining food safety. By following these guidelines and incorporating best practices into your daily routine, you can ensure a safe environment for preparing food and protect your customers from potential health risks.
