Carrot allergy is an allergic reaction to certain proteins found in carrots. It is relatively uncommon but can occur in individuals with sensitivities to certain plant-based foods. Carrot allergy is sometimes associated with Oral Allergy Syndrome (OAS), especially in those who are allergic to birch or mugwort pollen, due to cross-reactivity of similar proteins....


What are symptoms of carrot allergy?

  • Itchy or tingling sensation in the mouth and throat
  • Swelling of the lips, mouth, tongue, or throat
  • Hives or skin rash
  • Gastrointestinal discomfort, such as nausea, vomiting, or diarrhea
  • Nasal congestion or sneezing
  • In rare cases, anaphylaxis, a severe and potentially life-threatening reaction

What foods cross-react with carrot allergy?

Cross-reactivity can occur with other foods, particularly for those with Oral Allergy Syndrome. These might include:

  • Other vegetables, such as celery and parsley
  • Certain fruits, including apples and pears
  • Nuts, especially hazelnuts and almonds

When should I consider getting a carrot allergy test?

  • If you experience symptoms of an allergic reaction after eating carrots.
  • If you have a known allergy to birch or mugwort pollen and experience symptoms when eating raw carrots.
  • If you have experienced reactions to other foods that may cross-react with carrot allergies.

How do I reduce my carrot allergy symptoms?

  • Avoid raw carrots and products containing carrot ingredients.
  • Cook carrots, as heating can often alter the allergenic proteins and reduce symptoms.
  • Read food labels carefully to identify hidden sources of carrot.
  • In cases of mild reactions, over-the-counter antihistamines may help relieve symptoms.
  • Carry an epinephrine auto-injector if prescribed for severe allergies.
  • Consult with an allergist for accurate diagnosis and advice on managing the allergy, including potential immunotherapy for associated pollen allergies.
