Peanut allergy foods to avoid: what to know

Cross-contact happens when a small amount of peanut transfers through shared equipment, utensils, oil, surfaces, or storage containers. A food that does not list peanut as an ingredient may still be unsafe if its preparation is uncertain. Risk depends on the person and the exposure; do not decide safety from appearance or smell. An allergist can explain your individual precautions.

Keep separate utensils and spreads when advised, wash hands and surfaces, and do not share food. Tell restaurant staff clearly about the allergy and ask how the meal is prepared. Teach caregivers and school or workplace contacts what to avoid and how to respond. Carry prescribed emergency medicine and check its expiry as part of your routine.

Itchy throat, hives, swelling, repeated vomiting, cough, wheeze, breathing difficulty, dizziness, or collapse can be signs of a serious allergic reaction. Follow your emergency plan, use prescribed adrenaline when directed, and call emergency services. Symptoms can worsen quickly, so do not wait to see whether they settle or drive yourself if you feel faint.

Ask whether you need formal allergy testing, which precautionary label phrases matter, and how to handle restaurants, travel, school, or work. Confirm when to use emergency medicine, when to call for help, and whether follow-up with an allergy specialist is appropriate.
