What Is a Tree Nut Allergy?
A tree nut allergy occurs when the immune system mistakenly identifies proteins in tree nuts as harmful, triggering an allergic reaction. It is one of the most common food allergies in Australia, affecting both children and adults.
Tree Nuts vs Peanuts
It is important to note that peanuts are not tree nuts. Peanuts are legumes, while tree nuts grow on trees. Some individuals are allergic to both, but many only react to tree nuts.
How Tree Nut Allergies Work
When someone with a tree nut allergy consumes or comes into contact with tree nuts, their immune system releases chemicals such as histamine. This can cause symptoms ranging from mild discomfort to life-threatening anaphylaxis.
Common tree nut allergy symptoms include:
- Skin reactions such as hives, redness or swelling
- Stomach pain, nausea or vomiting
- Nasal congestion or sneezing
- Difficulty breathing
- Swelling of the lips, tongue or throat
Anaphylaxis requires immediate treatment with an adrenaline auto-injector (such as an EpiPen) and a call to 000.

How to Read Food Labels in Australia
Australian labelling laws require that tree nuts be clearly listed on packaging. Under Plain English Allergen Labelling (PEAL), tree nuts must appear in either the ingredient list or a separate allergen statement.
Understanding ‘May Contain’ Warnings
- Contains tree nuts: the product has tree nuts as an ingredient.
- May contain traces: risk of cross-contact during production.
- Made in a facility that also processes nuts: possible contamination risk.
According to FSANZ, accurate allergen labelling is a legal requirement. If unsure, always contact the manufacturer before consuming.
