Duck meat allergy
Allergy to duck meat.
About duck meat allergy
Allergy to duck meat is uncommon. Like other poultry allergies, it can occur as a direct IgE-mediated allergy to duck-muscle proteins, or through the bird-egg syndrome, in which sensitisation to bird proteins (from egg or from contact with birds and feathers) cross-reacts with proteins in poultry meat. In both cases the immune system produces IgE antibodies that drive the reaction. Duck is eaten less often than chicken in the UK, so reactions are reported less frequently.
Symptoms usually begin within minutes to two hours of eating and can include an itchy mouth, hives, swelling, stomach upset and wheezing; more severe whole-body reactions are possible but uncommon. As with some other meat allergies, thorough cooking may alter certain proteins so that some people tolerate well-cooked duck better than rare meat, although this varies. A person allergic to duck may or may not react to chicken and other poultry, and testing can help clarify how far avoidance needs to extend.
Diagnosis is made by an allergy specialist using the history alongside skin-prick or specific-IgE blood tests, sometimes with component testing to explore the egg-bird link, and a supervised food challenge where needed. Management is based on avoiding duck, and any related poultry that also causes trouble, while reading labels on pâtés, stocks and prepared dishes. People at risk of severe reactions may be prescribed an adrenaline auto-injector. Treat any severe reaction as an emergency and call 999.
Common triggers
- Duck meat and products containing it
Symptoms
- Itching or tingling in the mouth
- Hives, itching or eczema
- Swelling of the lips, face, tongue or throat
- Stomach cramps, nausea, vomiting or diarrhoea
- Wheezing or trouble breathing
- In severe cases, anaphylaxis
Avoidance & management
- Read ingredient labels every time
- Ask about ingredients and cross-contamination when eating out
- Keep the food out of shared cooking areas
- Carry prescribed antihistamines or an adrenaline auto-injector
- Seek emergency help for any severe reaction

Allergy safety: what everyone should know
Mild-to-moderate reaction signs
- Itching, hives or a raised rash
- Swelling of lips, face or eyes
- Tingling mouth, sneezing, runny nose
- Stomach pain, nausea or vomiting
Anaphylaxis — call 999 (UK) or 112 (EU) immediately
- Difficult or noisy breathing, wheeze, persistent cough
- Swelling of the tongue or tightness in the throat
- Dizziness, collapse, pale and floppy (young children)
- Use an adrenaline auto-injector (e.g. EpiPen) at once if prescribed, then call an ambulance even if symptoms improve
Allergy or intolerance? A true allergy involves the immune system and can escalate quickly; an intolerance (e.g. lactose intolerance) is unpleasant but not life-threatening. The symptoms overlap, so self-diagnosis is unreliable.
Getting tested: home-testing kits based on IgG are not diagnostically valid. If you suspect an allergy, ask a GP for referral to an allergy clinic for skin-prick or specific-IgE testing and a supervised food challenge where appropriate.
