Myths & FAQs
Shellfish allergy is an immunoglobulin E (IgE) antibody-mediated allergy. This means that when you ingest shellfish, your immune system overreacts by producing IgE antibodies which bind to mast cells. Once the shellfish protein allergen binds to the IgE antibody on the mast cell, the mast cell will release histamines that trigger allergy symptoms.
How Common is Shellfish Allergy?
- Urticaria (hives), an itchy skin rash of raised red spots
- Angioedema, or swelling under the skin
- Anaphylaxis, which is when multiple body systems produce a significant immune response causing a rapid drop in blood pressure and possible circulatory shock that is life-threatening
- GI symptoms such as nausea, vomiting, cramping, and diarrhea
- Lightheadedness and fainting
Sometimes, patients can have shellfish asthma reactions. For example, when exposed to an environment where shellfish is cooking or being processed, vapors from the shellfish may induce asthma.
Many foods contain shellfish products that can trigger an allergic response, some of which are especially popular here in New Orleans.

Shellfish allergy tests include skin and blood tests to help aid in the diagnosis of a shellfish allergy. However, neither test is conclusive because a positive result to a certain food does not always mean you will react to that food when you ingest it. In addition, neither the size of the wheal nor the numerical value of the IgE antibodies predicts how severe your allergic reaction to shellfish will be. Negative skin and blood tests are most useful because they can help rule out a shellfish allergy.
