Celery and products thereof
Celery is consumed as raw or as a cooked vegetable. Celery spice is used in many processed foods such as spice mixtures, soups, broths and salad dressings.
Allergy to celery is associated with allergy to birch pollen and also allergy to mugwort pollen. The most common symptom is oral allergy syndrome as for several other pollen related food allergies. However, serious reactions to celery such as anaphylaxis have been reported. Raw celery, cooked celery and celery spice have all caused reactions although some individuals may not react to cooked celery.
Symptoms
Local reactions in the mouth such as itching, but also systemic reactions affecting the skin, the nose and lungs and the stomach or severe life threatening reactions (anaphylaxis) have been observed upon ingestion of celery. Compared to allergic reactions to other fresh vegetables the course of celery allergy is often more severe.
