Prepare a short explanation

Write the allergens you need to avoid in language the people preparing food can understand. If traveling, have the wording checked by a competent speaker rather than relying only on automatic translation. Include a direct question about ingredients and preparation, not merely a request for healthy food. For example, ask whether a sauce includes your allergen and whether the utensils are shared. Tell staff about the allergy before ordering instead of assuming a menu symbol tells the complete story.

Keep a fallback when answers are unclear

Plan an alternative meal or an appropriately labeled packaged option that you can review using your usual process. Check imported products on their own labels rather than assuming that familiar packaging means a familiar recipe. Buffet dishes, bakery items, and sauces may not have a useful barcode at all. If staff cannot establish ingredients or explain relevant preparation practices, do not let hunger or a favorable app screen settle the decision. You can decline the meal and choose another arrangement.

Separate emergency action from product research

Keep prescribed emergency medication accessible and follow your clinician’s action plan. Before travel, know how to contact emergency services where you will be. Breathing difficulty, throat swelling, or faintness after possible exposure can indicate a serious reaction requiring immediate help. For suspected anaphylaxis, use your prescribed adrenaline auto-injector as instructed and contact local emergency services; do not wait for a scan or another ingredient search. The NHS guidance linked here gives emergency context, while your own prescribed plan and local emergency instructions take priority.

Take it with you

  • Explain the allergy and ask about ingredients and preparation.
  • Have a fallback when reliable answers are unavailable.
  • Treat suspected anaphylaxis as an emergency, not a scanning task.
