Latex allergy and foods

Some proteins in natural rubber latex resemble proteins in particular foods. The immune system may recognise these proteins as similar, causing symptoms after eating a food or after latex exposure. Reported triggers can include banana, avocado, kiwi, chestnut, peach or tomato, but a person may react to one, several or none of these foods. A suspected food reaction does not prove latex allergy, and a latex allergy does not mean every listed food must be avoided.

Symptoms can include mouth itching, an [Itchy Throat](/symptoms/itchy-throat/), hives, swelling, vomiting, cough or wheeze. The pattern, timing and amount eaten matter when a clinician assesses the cause.

Keep a brief record of the food, preparation, amount, symptoms and timing, and mention reactions to gloves, balloons, dental equipment or medical devices. Do not deliberately challenge yourself with a suspected trigger at home. A clinician may arrange [Allergy Testing](/treatments/diagnostics-and-screening/allergy-testing/) and advise whether avoidance, an emergency plan or referral is appropriate. Read labels carefully and tell restaurants and healthcare workers about a confirmed allergy.

Call emergency services immediately for breathing difficulty, throat or tongue swelling, repeated vomiting, widespread hives with dizziness, collapse or sudden severe weakness after eating or latex exposure. These can be signs of [Anaphylaxis](/conditions/anaphylaxis/), which needs prompt treatment. Follow your prescribed emergency plan and use [Anaphylaxis Emergency Treatment](/treatments/acute-and-urgent-care/anaphylaxis-emergency-treatment/) as directed.

Does my history suggest latex allergy, food allergy or another explanation? Which foods should I avoid now, if any? Do I need testing or a supervised food challenge? Should I carry emergency medicine, and what should my family or workplace know?
