To the Editor: Allergen avoidance is the mainstay of food allergy management. Consumers with food allergies rely on accurate labelling of foods to avoid ingestion of allergens and subsequent allergic reactions. Current Australian legislation states that ingredients derived from common allergens (peanuts, tree nuts, eggs, wheat, cows milk, soy, fish, shellfish and sesame) must be clearly labelled.1 However, use of shared processing facilities can result in cross-contamination of other ingredients with these allergens. This has led to the use of advisory statements such as “may contain traces of” by manufacturers. A recent Food Standards Australia New Zealand survey found that consumers with food allergies are frustrated by such labelling.2 There is also confusion among the medical profession about whether to advise patients with food allergies to avoid all foods with allergen avoidance advisory statements. The perception by some in the general population and in the medical community is that these statements are so widely used that avoidance would be overly prohibitive. However, there are currently no published data on the extent of advisory labelling use in Australia.
