Colour-Coded Chopping Boards: a Practical Guide

Colour-coded chopping boards assign a different coloured board to each food group so staff have a fast visual way to keep raw and ready-to-eat food apart — the core of preventing cross-contamination. A common scheme uses red for raw meat, blue for raw seafood, yellow for raw poultry, green for salad and fruit, brown for cooked food and white for dairy and bakery. The colours themselves are not set by law, but the underlying separation generally is. Key takeaways: A common system uses red (raw meat), blue (raw seafood), yellow (raw poultry), green (salad and fruit), brown (cooked food) and white (dairy and bakery), with purple increasingly used for allergen-specific prep.. The colours are a tool, not a legal requirement — the underlying rule is keeping raw and ready-to-eat food and equipment separate.. One board per food group stops harmful bacteria transferring from raw food to food that won't be cooked again.. Colour-coding only works if boards are cleaned and sanitised between uses and replaced when badly scored or warped.. Put the system on the wall as a chart and train every food handler on it, including casuals and agency staff.. Common chopping board colour scheme: Colour, Food group. Red — Raw meat (beef, lamb, pork). Blue — Raw fish and seafood. Yellow — Raw poultry (chicken, turkey, duck). Green — Salad, fruit and vegetables. Brown — Cooked meat and ready-to-eat food. White — Dairy and bakery. Purple — Allergen-specific preparation (optional but recommended). What do the chopping board colours mean? There is no single legally mandated colour scheme in Australia, and schemes do vary between suppliers and kitchens. That said, most commercial kitchens use a widely recognised system built around one colour per food group, which makes it obvious at a glance whether a board is being used correctly and reduces mistakes during a busy service. The key is to choose one scheme, document it and make sure everyone follows the same one. Red — raw meat (beef, lamb, pork). Blue — raw fish and seafood. Yellow — raw poultry (chicken, turkey, duck). Green — salad, fruit and vegetables. Brown — cooked meat and ready-to-eat food. White — dairy and bakery. Purple — increasingly used for allergen-specific preparation (optional but recommended). Why colour-coding prevents cross-contamination Raw meat, poultry and seafood can carry harmful bacteria such as Salmonella, Campylobacter and E. coli. If the same board is used for raw chicken and then for salad that won't be cooked, those bacteria can transfer straight to food that goes to the customer as-is. Cross-contamination between raw and ready-to-eat food is one of the most common contributors to foodborne illness, so keeping them on separate boards removes a major risk. Keeps raw, high-risk food away from ready-to-eat food. Removes the guesswork about which board was last used for what. Makes correct practice the easy, visual default under pressure. Helps demonstrate a working control to an auditor or council environmental health officer. What the Food Standards Code actually requires The Australia New Zealand Food Standards Code does not specify board colours. What it generally requires is that food businesses take all practicable measures to prevent the contamination of food, and that equipment and surfaces are kept clean and, where necessary, sanitised. Colour-coded boards are one practical, well-understood way to meet those obligations — but a kitchen could meet them another way, such as dedicated prep areas or thorough clean-downs between tasks. Requirements and how they are enforced can vary, so confirm expectations with your state or territory food regulator and local council. Standard 3.2.2 generally requires preventing the contamination of food and keeping equipment clean and sanitised. Standard 3.2.2A requires many food service, catering and retail businesses to use food safety management tools and be able to show controls are working. Colour-coding is a recognised method, not a legal mandate — confirm what applies to you with your state or territory regulator and local council. How to implement the system in your kitchen A colour system only works if it is set up clearly and everyone follows it. Decide on your scheme, buy enough boards so staff never have to 'borrow' the wrong colour, and make the rules visible where prep happens. Storing boards in a colour-order rack and displaying a wall chart keeps the system self-explanatory for new and casual staff. Buy several boards per colour so there is always a clean one available. Put a laminated colour chart on the wall above prep benches. Store boards upright in a rack, separated by colour, not stacked. Include the system in induction and refresher training for all food handlers. Match knives, tongs and containers to the same colours where practical. Colour-coding and allergen cross-contact Cross-contamination isn't only about bacteria — traces of an allergen carried from one board to another can cause a serious reaction in a sensitive customer. Many kitchens add a purple board (and matching purple utensils) dedicated to preparing food for allergen-aware orders, kept scrupulously clean and stored separately. Standard 1.2.3 requires certain allergens to be declared, and preventing allergen cross-contact supports that duty. A dedicated board does not replace checking ingredients and cleaning thoroughly, but it adds a clear visual safeguard. Use a dedicated (commonly purple) board and utensils for allergen-aware preparation. Clean and sanitise thoroughly before allergen prep — visible cleanliness is not the same as allergen-free. Store allergen-prep equipment separately so it can't be grabbed for general use. Still verify ingredient labels; a board colour is a backup, not the whole control. Cleaning and sanitising between uses Colour-coding does not replace cleaning — boards still need to be cleaned and sanitised between different foods and whenever they are visibly soiled. Cleaning removes food and grease; sanitising then reduces bacteria to a safe level. Follow a two-step process and give any sanitiser its full contact time before the board is used or put away. Scrape off food debris, then wash in hot water with detergent. Rinse, then apply a food-safe sanitiser and leave for the label's stated contact time. Air-dry where possible — reusing a damp cloth can re-contaminate the board. A commercial dishwasher on a hot cycle both cleans and sanitises. Never use one board for two food groups without a full clean and sanitise in between. When to repair or replace a board Deep knife scoring, cracks and warping create grooves that trap food and bacteria and are very hard to sanitise. A board that can no longer be brought to a clean, smooth surface should be taken out of service. Plastic boards can sometimes be resurfaced a limited number of times, but heavily damaged boards should be replaced. Keeping worn boards in rotation quietly undermines the whole system. Retire boards with deep grooves, cracks, splits or a warped surface. Check boards during regular cleaning schedules, not just when they look bad. Replace like-for-like so the colour system stays complete. Worked examples: Switching from raw chicken to salad: A cook finishes portioning raw chicken on the yellow board and needs to prep salad. Reusing the same board without cleaning would transfer bacteria straight onto food that won't be cooked. They move to the green board and fully clean and sanitise the yellow one before it is used again. An allergen-aware order: A customer orders a sandwich made without their allergen. The kitchen uses the dedicated purple board and matching utensils, kept scrupulously clean and stored separately, and still checks the ingredient labels. The board colour is a backup safeguard, not a substitute for thorough cleaning and ingredient checks. Checklist: A defined colour scheme with a chart displayed at prep areas. Enough boards per colour that staff never substitute the wrong one. A dedicated board and utensils for allergen-aware preparation. Boards cleaned and sanitised between different foods and when soiled. Sanitiser given its full contact time before boards are reused. Scored, cracked or warped boards taken out of service. All food handlers, including casuals, trained on the system. Knives, tongs and containers colour-matched where practical. Common mistakes: Using the same board for raw poultry and salad without cleaning in between. Wiping a board with a reused cloth instead of properly cleaning and sanitising. Not buying enough boards, so staff grab whatever colour is free. Assuming a visibly clean board is safe for an allergen-aware order without a full clean and sanitise. Keeping deeply scored or warped boards in rotation because they 'still work'. Assuming the colours are a legal requirement rather than the separation behind them. Training only permanent staff and leaving casuals to guess the system.
