Colour-Coded Chopping Boards and Equipment
A system of colour-coded chopping boards and utensils used to prevent cross-contamination between different food types in commercial kitchens.
Colour coding is a widely adopted food safety practice in UK hospitality that assigns specific colours to chopping boards, knives, and other utensils based on the type of food they are used with. The purpose is to prevent cross-contamination, particularly between raw and ready-to-eat foods. While colour coding is not mandated by a specific regulation, it is considered an industry standard and is recommended by the FSA, the Chartered Institute of Environmental Health (CIEH), and most local authorities. EHO inspectors expect to see a colour-coding system in place as part of your cross-contamination controls under EC Regulation 852/2004. Not having one is likely to result in a lower confidence-in-management score during inspections.
Key Points
- Six standard colours: red (raw meat), blue (raw fish), green (salad/fruit), yellow (cooked meat), brown (vegetables), white (dairy/bakery)
- Recommended by the FSA and CIEH as an industry-standard cross-contamination control
- EHO inspectors expect colour coding as part of your HACCP or SFBB cross-contamination procedures
- Boards must be replaced when scored or damaged, typically every 6 to 12 months
- Staff training and visible wall charts are essential for the system to work
Standard Colour Assignments
The UK industry standard, based on the system promoted by the CIEH and the British Standard BS EN 12453, assigns six colours to different food types. Red is for raw meat. Blue is for raw fish and seafood. Yellow is for cooked meat. Green is for salad, fruit, and fresh produce that will not be cooked. Brown is for raw vegetables. White is for dairy products and bakery items. Some businesses add additional colours for specific purposes, but these six form the core system. The key principle is that boards and utensils used for raw products (especially raw meat and fish) must never come into contact with ready-to-eat foods.
Implementing a Colour-Coding System
A colour-coding system is only effective if it is properly implemented and maintained. Every food preparation area should have a complete set of colour-coded boards available. A wall chart showing which colour corresponds to which food type should be displayed in a visible location. All staff must be trained on the system during induction and refreshed regularly. Boards must be replaced when they become scored, stained, or damaged, as deep cuts can harbour bacteria that survive cleaning. Many businesses extend colour coding beyond boards to include knife handles, cloths, and storage containers for a comprehensive approach.
Cleaning and Replacement
Colour-coded boards must be thoroughly cleaned and sanitised after each use. They should be washed in hot water with detergent, then sanitised with a food-safe disinfectant or run through a commercial dishwasher at 82 degrees Celsius or above. Boards should be stored upright to air dry. Plastic boards should be replaced when deep scoring makes them difficult to clean effectively. As a general guide, boards in heavy use should be replaced every 6 to 12 months, though this depends on usage. Wooden boards are not recommended in commercial kitchens as they are more difficult to sanitise thoroughly.
Frequently Asked Questions
Is colour coding chopping boards a legal requirement?
There is no specific UK regulation that mandates colour-coded chopping boards. However, EC Regulation 852/2004 requires food businesses to have adequate procedures to prevent cross-contamination. Colour coding is the recognised industry standard for meeting this requirement. EHO inspectors will expect to see some form of separation system, and colour coding is by far the most widely accepted approach.
What happens if you use the wrong coloured board?
Using the wrong board creates a cross-contamination risk. If a board used for raw chicken is then used for ready-to-eat salad, harmful bacteria like Salmonella or Campylobacter could transfer to the salad and cause food poisoning. This type of cross-contamination is one of the leading causes of foodborne illness outbreaks in the UK. If an EHO observes this during an inspection, it could result in a significantly reduced hygiene rating.
Can you use a different colour-coding system to the standard?
Yes. There is no legal requirement to follow the exact six-colour system. Some businesses use different colours or add extra categories. The key is that your system is consistent, documented in your food safety management system, understood by all staff, and effectively prevents cross-contamination between raw and ready-to-eat foods.
Do you need colour-coded knives as well as boards?
It is strongly recommended. Using a colour-coded board but the same knife for different food types undermines the purpose of the system. Many commercial kitchen suppliers sell knife sets with colour-coded handles that match the board system. Extending colour coding to cloths, containers, and other utensils provides the most robust protection against cross-contamination.
