Maintaining a clean and sanitized kitchen is paramount, whether you’re operating a high-end restaurant or a school cafeteria. Foodborne illnesses affect millions annually, emphasizing the need for stringent hygiene practices. Understanding which surfaces require cleaning and sanitizing is crucial for food safety.
If you’re involved in the food industry, from restaurants to food trucks, knowing how to properly clean and sanitize food contact surfaces is essential for creating a safe environment for both customers and employees.
This article will guide you through:
- Defining food contact surfaces.
- Explaining the importance of cleaning and sanitizing these surfaces.
- Establishing a cleaning and sanitizing schedule.
- Providing practical sanitizing methods.
- Offering tips for maintaining safe food contact surfaces.
- Highlighting common sanitizing mistakes.
Understanding Food Contact Surfaces
A food contact surface is any surface that directly interacts with food intended for human consumption.
Typical examples include:
- Utensils
- Cutting boards
- Plates
- Serving trays
- Counters
- Tables
Appliances like microwaves and refrigerators are also considered food contact surfaces due to potential spills or splatters.
Ideally, food contact surfaces should be made of food-grade materials that are smooth, non-absorbent, and easy to clean. They should also be durable enough to withstand temperature variations and sanitizing chemicals.
Non-food contact surfaces, such as walls, ceilings, floors, and the exteriors of doorknobs, still require regular cleaning but not necessarily sanitizing. Creating a regular disinfecting schedule for these areas is advisable. The key difference lies in whether the surface comes into direct contact with food.

The Importance of Cleaning and Sanitizing Food Contact Surfaces
Cleanliness is vital in food service. Cleaning and sanitizing food contact surfaces is essential for preventing food contamination and foodborne illnesses. Neglecting this can lead to the spread of harmful bacteria like Salmonella and E. coli.
Germs can survive on surfaces for extended periods, making regular cleaning and sanitizing critical. These practices significantly reduce the risk of harmful microorganisms lingering on surfaces that come into contact with food.
Regular cleaning and sanitizing are key to preventing cross-contamination, where bacteria transfer from one surface, object, or food to another. Proper sanitation protects customers and maintains a safe and healthy environment.
When to Clean and Sanitize Food Contact Surfaces
While thoroughness is always beneficial, certain situations demand immediate cleaning and sanitizing:
After Handling Raw Meat, Poultry, or Eggs
Raw meat, poultry, and eggs may contain bacteria like Salmonella, E. coli, and Campylobacter.
These bacteria can easily spread, causing foodborne illnesses. Cleaning and sanitizing surfaces after contact with these items is essential to prevent pathogen transmission.

Before and After Preparing Different Types of Food
Cross-contamination is a leading cause of foodborne illnesses. Bacteria from one food item can transfer to another through contaminated surfaces.
Cleaning and sanitizing before and after preparing different foods prevents this. For example, sanitize the surface after preparing raw meat before using it for vegetables.
After Handling Garbage or Cleaning Chemicals
Garbage and cleaning chemicals can harbor harmful bacteria and contaminants. After handling these, wash your hands and sanitize any surfaces that may have been in contact.
When Surfaces Are Visibly Soiled or Contaminated
Clean and sanitize food contact surfaces when visibly soiled or contaminated, whether from spills, food debris, or other contaminants. This prevents the spread of harmful bacteria.
How to Sanitize Food Contact Surfaces
Understanding the difference between cleaning and sanitizing is crucial.
Cleaning vs. Sanitizing: What’s the Difference?
Cleaning removes visible dirt and debris from surfaces through scrubbing and wiping. It’s a vital first step in removing potential bacteria.
Sanitizing reduces the number of pathogens on a surface to a safe level using chemicals or heat.
Sanitizing correctly prevents the spread of illness. The right method or chemical should target the specific pathogen (e.g., bactericides kill specific microorganisms, antiseptics prevent putrefaction).
Using the Right Cleaning Products
Select cleaners designed to kill bacteria and germs. Use products recommended for commercial kitchens and follow the manufacturer’s instructions.
Different surfaces require different cleaning methods. Stainless steel can withstand harsher chemicals, while wood may need replacement if damaged by chemicals.

How to Clean Different Types of Surfaces
Cutting boards can harbor bacteria if not cleaned properly. Scrub them thoroughly after each use. Use separate boards for raw meat and poultry to avoid cross-contamination. Plastic boards can go in the dishwasher, while wooden boards should be scrubbed with hot water and vinegar, followed by salt.
Wash utensils in hot, soapy water, using a brush to reach all areas. Load utensils handle-side up in the dishwasher.
Countertops vary in material. Avoid acidic cleaners like vinegar on granite; use soap and water or specialized granite cleaner. For laminate or plastic countertops, a water and vinegar mixture works well.
Sanitizing kills remaining bacteria. Use a commercial sanitizer recommended for foodservice, wear gloves, and follow all instructions and guidelines.
Tips for Maintaining Safe Food Contact Surfaces
Maintaining safe food contact surfaces involves more than just cleaning and sanitizing. It requires a comprehensive approach:
Develop a Cleaning Routine
Establish a regular cleaning and sanitizing schedule for all food contact surfaces, including cutting boards, utensils, and counters.
Regularly inspect and maintain kitchen equipment to identify and correct defects early.
Use Separate Cutting Boards and Utensils for Different Types of Foods
Use separate cutting boards and utensils for meat, fish, and vegetables, as well as separate utensils for raw and cooked foods.
Keeping raw meat separate is especially important to prevent cross-contamination and foodborne illnesses.
Thoroughly Clean and Inspect Food Contact Surfaces Before and After Use
Scrub cutting boards and utensils with warm, soapy water and a brush to remove food particles. Pay attention to hard-to-reach areas.
Inspect surfaces for wear and tear that could cause physical hazards. Replace damaged equipment immediately.
Use Cutting Board Mats
Use cutting board mats as a barrier between food and the board to minimize contamination.
These mats are easy to clean and replace. Color-code them for different types of food.
Avoid Cross-Contamination
Organize prep areas and separate cutting boards and utensils by food type.
Wash hands and sanitize tools between each use.
Store Materials Properly
Store cutting boards and utensils in a designated area away from contaminants. Ensure they are dry before storing to prevent bacterial growth. Store food in appropriate containers at the correct temperature.
Maintain a Cleaning Checklist
Use a cleaning checklist to ensure regular maintenance of food contact surfaces. Wipe down prep areas and equipment after each use with a sanitizing solution.
Deep clean the kitchen weekly, including floors, walls, and ceilings.
Common Mistakes to Avoid When Sanitizing
Several common mistakes can undermine sanitizing efforts:
Not Cleaning Thoroughly
Spotty cleaning can result from rushing or using inadequate tools. Sanitizing is not a substitute for cleaning.
Sanitize surfaces properly using the right products and techniques to eliminate microorganisms.
Using the Wrong Supplies or Products
Choose the right sanitizer for the specific surface or equipment. Bleach is suitable for non-porous surfaces but not for wood.
Read labels and select products designed for kitchen use.
Not Replacing Cleaning Supplies Regularly
Contaminated cleaning cloths and sponges can worsen the problem.
Replace cleaning supplies regularly and use separate supplies for different areas.
Rushing Things
Taking shortcuts compromises proper sanitizing.
Follow all steps and protocols to sanitize food contact surfaces and equipment properly.
The Takeaway
Proper cleaning and sanitation of food contact surfaces are critical for food safety. Understanding what constitutes a food contact surface, how to clean it, and when to sanitize it are key to keeping your customers and employees safe. By following these guidelines, you can maintain a clean, safe, and healthy environment in your food service establishment.
