Allergies are common and are increasing in Australia. An allergy occurs when someone’s immune system reacts to a substance that is harmless for most people. These substances are known as allergens. Peanuts and tree nuts can cause allergies in some children. Peanut allergies occur in about 1 in 50 children and 1 in 200 adults.

Packaged foods that contain nuts must state this on the label. You can also look for the statement ‘May contain traces of nuts’ on labels which indicates there’s a possibility that traces of nuts might be present in the food unintentionally, if, for example, the food is prepared on the same equipment as products that contain nuts.
