A protein found in wheat, rye, barley, oats and spelt that must be declared under the Food Standards Code and must be strictly avoided by people with coeliac disease. Gluten is a protein naturally present in certain cereals, specifically wheat, rye, barley, oats and spelt, and their hybrid strains. Under the Australia New Zealand Food Standards Code, cereals containing gluten are among the declared allergens, so their presence must always be made clear on food. For people with coeliac disease, eating gluten triggers an immune response that damages the small intestine, so avoidance must be complete and lifelong. It is important to distinguish gluten from wheat: someone can be allergic to wheat specifically, or need to avoid all gluten sources because of coeliac disease. This is why labelling has to identify the source, and why the Code sets separate meanings for the claims gluten free and low gluten. In Australia a gluten free claim means no detectable gluten, which is a strict standard, while low gluten has its own defined limit. For a food business, handling gluten means both declaring it accurately and, where a gluten free product or dish is offered, being able to stand behind that claim. Because a gluten free claim in Australia means no detectable gluten, offering gluten free food demands rigorous control of cross-contact from flour dust, shared equipment, fryers, toasters and preparation surfaces, not just leaving out gluten-containing ingredients. In practice that means checking every ingredient and its supplier specification for hidden gluten (in sauces, thickeners, crumbed products and the like), preparing gluten free orders carefully to avoid cross-contact, and being honest when a kitchen cannot guarantee a dish is gluten free. Many venues treat coeliac customers with particular care because even small amounts of gluten can cause them harm. A pub advertises gluten free chips but fries them in the same oil used for battered fish. The battered fish sheds gluten into the oil, so the chips are no longer free of detectable gluten. A coeliac customer orders them trusting the gluten free claim and becomes unwell. The ingredients on the chips were fine; the shared fryer caused cross-contact that made the gluten free claim untrue.
Frequently asked questions
Which grains contain gluten under the Food Standards Code?
Gluten is found in wheat, rye, barley, oats and spelt, and their hybrid strains. Cereals containing gluten are declared allergens, so their presence must be declared on food regulated by the Australia New Zealand Food Standards Code.
What does a gluten free claim mean in Australia?
In Australia a gluten free claim means the food contains no detectable gluten. This is a strict standard, so businesses must control cross-contact carefully, not just omit gluten-containing ingredients, before labelling or describing a food as gluten free.
Is gluten intolerance the same as coeliac disease?
No. Coeliac disease is an immune condition where gluten damages the small intestine and must be avoided completely. Some people report non-coeliac gluten sensitivity with different symptoms. Either way, food businesses should treat gluten free requests seriously and accurately.
Why does frying gluten free food in shared oil matter?
Gluten from battered or crumbed foods transfers into shared fryer oil, so anything cooked in that oil can pick up detectable gluten. This cross-contact can make a gluten free claim untrue and cause harm to coeliac customers, so a dedicated fryer is needed.
Do I need to declare gluten even in small amounts?
When a gluten-containing cereal is a deliberate ingredient it must be declared regardless of amount. For unintended trace gluten from cross-contact, that is addressed through control measures and, where relevant, voluntary precautionary labelling rather than a Contains declaration.
