Cereals containing gluten (wheat, rye, barley, oats, spelt and their hybrids), crustacea, egg, fish, milk, peanuts, tree nuts, sesame, soy, lupin, added sulphites at 10 mg/kg or more, and molluscs. All must be declared when present in food.
Added sulphites must be declared when present at a concentration of 10 mg/kg or more in the food. Below that level declaration is not required, but sulphites are still a common cause of adverse reactions.
Tree nuts are a declared allergen category, but the specific tree nut present should be named (for example almond, cashew or walnut) so consumers with a specific tree nut allergy can identify the risk accurately.
Yes. Lupin is one of the declared allergens under the Food Standards Code. It is a legume sometimes used in flours and meat alternatives, and it can cause allergic reactions, including in some people allergic to peanut.
When a declared allergen is a deliberate ingredient it must be declared no matter how small the amount. The situation is different for unintended trace presence from cross-contact, which is handled through voluntary precautionary labelling rather than a mandatory Contains declaration.
