Tree nuts such as almonds, cashews and walnuts can be found in a variety of foods including chocolate, cereal, muesli bars, and bakery items. Avoiding tree nuts is essential for people with confirmed tree nut allergy.

The words “may contain traces of tree nuts” on a food label indicates that the food is made in a facility that makes other foods containing tree nuts. Raw ingredients may be contaminated with tree nuts even though the food does not contain tree nuts as an ingredient.

Unlabelled food or food consumed outside the home has a higher risk than food labelled as possibly containing traces. Discuss what to do about these foods with a clinical immunology/allergy specialist.

Prepared food that is not labelled (such as food from cake shops, food malls and restaurants), may contain or be contaminated with tree nuts.

While nuts can look and taste similar, it is possible to be allergic to only one nut or to more than one nut. Discuss what to do about other nuts with a clinical immunology/allergy specialist.

The food lists included in this document are not exhaustive. People with food allergy should always check foods labels each time products are purchased.
