Colour-Coded Knife Handles: Why Australian Food Businesses Use Them
, by Outback Edge Imports, 13 min reading time
There is no national law in Australia that assigns a knife-handle colour to a particular food. Here's what food-safety rules actually require, the common colour conventions, and how to build a colour system that works.
Walk into any busy commercial kitchen, butcher shop or seafood room and you'll see it — knives and boards colour-matched to the job. Red for one task, blue for another, yellow for something else. It looks like a rule everyone's following. So new food businesses often ask us the same thing: which colour knife is legally required for which food in Australia?
The honest answer surprises people. There is no national law in Australia that assigns a particular handle colour to a particular food. Colour coding is a practical, widely-used tool for keeping food-prep tasks separate — but it isn't the law itself, and no regulation names a colour. This guide explains what Australian food-safety rules actually require, where the familiar colour conventions come from, and how to build a colour system that genuinely reduces cross-contamination rather than just looking the part.
Why food businesses use different knife-handle colours
Colour coding solves a simple, real problem: in a fast kitchen, you need to tell at a glance that the knife in your hand is the right one for the job — and that it hasn't just come off raw chicken. A colour system gives staff an instant visual cue that supports the actual goal, which is keeping raw and ready-to-eat foods apart.
The practical benefits are worth spelling out:
Faster separation of raw and ready-to-eat. The single biggest cross-contamination risk is a blade moving from raw meat, poultry or seafood to food that won't be cooked again — salad, cooked meat, bread. A dedicated coloured knife for each task makes that mistake harder to make.
Quick identification under pressure. When a kitchen is slammed, people reach for whatever's closest. Colour removes the guesswork so the right tool gets grabbed without stopping to think.
Easier staff training and audits. "Red is raw meat only" is far easier to teach a new starter — and for a supervisor or auditor to check — than a written procedure no one reads. It turns your food-safety plan into something visible on the bench.
It coordinates with your boards. Most kitchens already run colour-coded cutting boards. Matching the knives to the same system keeps the whole workflow consistent from board to blade.
Allergen awareness. Some sites set aside a colour for allergen-controlled prep — though, as we'll cover below, colour alone is never enough for allergen management.
Are colour-coded knives legally required in Australia?
In almost all cases, no. What the law requires is the outcome — no cross-contamination — not any particular method of getting there.
Australian food businesses operate under the Australia New Zealand Food Standards Code, which each state and territory gives legal force (in Queensland, for example, through the Food Act 2006). The parts that matter for knives are in Standard 3.2.2 – Food Safety Practices and General Requirements:
Businesses must take all necessary steps to prevent the contamination of food. Food-contact surfaces — knives and boards included — must be cleaned and sanitised whenever contamination is likely, such as after cutting raw meat and before handling ready-to-eat food. Equipment must be kept in good repair and working order, and food-contact surfaces must be made of materials that are effectively cleanable and won't contaminate food.
Read those together and the real legal requirement is clear: keep raw and ready-to-eat foods separate, clean and sanitise between incompatible tasks, and use equipment you can actually keep hygienic. You can meet that with separate knives, or by cleaning and sanitising thoroughly between jobs, or by separating tasks by area or time. Colour coding is one convenient way to organise the "separate knives" approach — but the Code never says a colour is compulsory.
There's an important exception. Colour coding can become effectively mandatory inside a particular workplace when it's written into that business's own documented food-safety program, HACCP plan or standard operating procedure — or required by a customer, franchise, hospital, aged-care provider, processing establishment or auditor. Under Standard 3.2.1, a business that's required to have a food-safety program must follow the program it has documented. So if your plan says "red-handled knives are for raw meat only," your staff must follow it — not because red is mandated nationally, but because your own program now requires it.
The common Australian colour conventions
If there's no legal chart, why does everyone seem to use the same colours? Because the industry has settled on a loose convention, and the clearest government-published version comes from the NSW Food Authority. Its guidance is written for cutting and serving boards, but businesses commonly extend the same scheme to knife handles.
| Colour | Common example use | Legal status |
|---|---|---|
| Blue | Raw fish and seafood | Industry convention |
| Red | Raw meat | Industry convention |
| Yellow | Raw poultry | Industry convention |
| Green | Fruit and vegetables | Industry convention |
| White | Bakery, bread and dairy | Industry convention |
| Brown | Cooked meat | Industry convention |
| Purple | Sometimes used for allergen-controlled prep | No prescribed Australian meaning |
These are common industry examples, not mandatory Australian colour assignments. Always follow your workplace's documented food-safety program and local regulatory requirements.
Here's the tell that proves it's a convention and not a law: the NSW Food Authority itself states that it doesn't matter which colours you use — what matters is that staff are trained in, or have knowledge of, which colour is used for each purpose. The Authority even recommends putting up a sign or poster so the system is clear to everyone. And its own materials aren't perfectly consistent from one document to the next. A national legal standard wouldn't leave the choice of colour up to the business; the fact that it does tells you this is a helpful framework, not a rulebook.
Why colour systems differ from kitchen to kitchen
Compare a few published colour charts — Australian and overseas — and you'll spot disagreements. Some put yellow on raw poultry; some use it for cooked meat. Some separate raw meat and raw chicken by colour; others lump them together. None of that means anyone is doing it wrong. It means the colour scheme is a tool each business adapts to its own layout, menu and risks.
What actually makes a colour system work isn't picking the "correct" colours — it's consistency and training. A simple system that every staff member understands and follows beats an elaborate seven-colour scheme that only the head chef remembers. Pick a scheme, write it down, put it on the wall, and train to it.
How to set up a colour system that actually works
If you're introducing colour coding, keep it practical:
Start from your real risks. The non-negotiable separation is raw protein from ready-to-eat food. Build your colours around that first, then add distinctions only where they earn their place.
Keep it simple. Three or four colours that everyone follows beats a rainbow no one can remember. Match your knives to the boards you already run.
Write it into your food-safety program. A colour system only has teeth if it's documented. Put it in your plan, define what each colour means in your kitchen, and make it part of induction for new staff.
Make it visible. A laminated chart on the wall turns the system into something staff and auditors can check at a glance.
Store colours separately. Colour coding does nothing if all the knives live in the same block or magnetic strip and get grabbed at random. Give each colour its own storage.
Colour coding never replaces cleaning and sanitising
This is the point most retailers skip, and it's the most important one. A red-handled knife is not a clean knife. Colour coding reduces the chance of using the wrong blade — it does nothing about bacteria already on a blade you're reusing.
The law's core requirement stands regardless of colour: food-contact surfaces must be cleaned and sanitised whenever contamination is likely. Even a perfectly colour-coded kitchen still has to wash, clean and sanitise knives between tasks and at the required intervals. Treat colour as a layer on top of good cleaning discipline — never as a substitute for it. For the day-to-day routine, our guide on maintaining your knives covers cleaning and care properly.
The trap: don't judge a knife by its factory handle colour
Here's where a lot of buyers get caught out. It's tempting to assume a yellow-handled knife is "the poultry knife" and a black one is general-purpose. That's not how manufacturers work.
The clearest example is Swibo — Victorinox's dedicated processing range, and a favourite of Australian butchers and anglers. Swibo's signature yellow handle runs right across the range: boning knives, skinning knives, butchering knives and fish-processing blades all wear the same yellow. Here, yellow is brand identity, not a food category. Reading a Swibo yellow boning knife as "poultry only" would be a genuine mistake. (See our Swibo fishing knives guide for how the range is actually used.)
Likewise, a black handle is usually just a manufacturer's standard colour, and a red or blue handle simply makes a knife suitable for inclusion in a colour system — it doesn't lock the knife to one job.
What actually matters for hygiene is the handle construction. A sealed, non-porous handle with no seams, gaps or micro-cracks for bacteria to hide in — and a blade you can clean and sanitise properly — does far more for food safety than the colour ever will. That's why professional ranges like Victorinox Fibrox and Dexter Russell Sani-Safe are built around moulded, hygienic, easy-clean handles in the first place. If you want the deeper detail on materials and cleanability, our carbon vs stainless steel guide is a good companion read.

Frequently asked questions
Are colour-coded knives a legal requirement in Australia? No. Australian food-safety law requires you to prevent cross-contamination and to clean and sanitise food-contact surfaces when contamination is likely — it doesn't mandate any knife colour. Colour coding is an optional tool that helps you meet those obligations. It can, however, become compulsory within a specific workplace if it's written into that business's documented food-safety program or required by a customer or auditor.
What do the knife handle colours mean? By common industry convention: blue for raw seafood, red for raw meat, yellow for raw poultry, green for fruit and vegetables, white for bakery and dairy, and brown for cooked meat. These are examples, not law — your workplace defines its own meanings and trains staff to them.
Does a coloured knife mean I don't have to clean it as often? No — and this is the most important thing to get right. Colour coding reduces the chance of grabbing the wrong knife; it does nothing about bacteria on a blade you reuse. You must still clean and sanitise between tasks exactly as the food-safety standards require.
Is a yellow Swibo knife only for poultry? No. Swibo's entire range — boning, skinning, butchering and fish knives — uses a yellow handle as brand identity. Assign it in your own system based on how you use it, not on the factory colour.
What about allergen control — is purple the allergen colour? There's no prescribed Australian allergen colour. Allergen management needs a documented plan, segregated and labelled equipment, staff training and cleaning between different allergen profiles. Colour can support that, but colour alone is never enough.
The bottom line
Colour-coded knife handles are a smart, practical way to keep food-prep tasks separate and cross-contamination down — but they're a tool, not a legal code. Australian law asks you to keep raw and ready-to-eat foods apart and to clean and sanitise as you go; it never names a colour. Choose knives for their edge and their hygienic, sealed construction first, build a simple colour system your whole team understands, write it into your food-safety program, and keep cleaning regardless. Do that and colour coding earns its place.
