Shellfish Allergy

What is a shellfish allergy?

Shellfish allergy is an abnormal immune reaction to the proteins found in shellfish.

Is shellfish allergy common?

Shellfish allergy is a relatively common food allergy in children and the most common food allergy in adults. Approximately 2% of adults will be allergic to some type of shellfish.

What are the symptoms of an allergic reaction to fish?

Classic allergic reactions usually include a red, itchy rash called hives that occurs within minutes of ingesting foods containing shellfish. Hives can progress to or occur as part of a more serious allergic reaction, called anaphylaxis. Anaphylaxis is a life-threatening allergic reaction that may include any of the following symptoms: wheezing or other breathing problems; vomiting, diarrhea or stomach cramps; face, mouth, or throat swelling; or signs of shock, including low blood pressure, dizziness, and passing out.

Do people outgrow shellfish allergy?

In most individuals the allergy to shellfish is lifelong. It is possible that some individuals may outgrow the allergy, but this is probably rare.

What are the shellfish?

Examples of shellfish include crustaceans (lobsters, shrimp, prawn, crayfish, rock lobster or kreef) and mollusks (abalone, snails, mussels, oysters, clams, squid, and octopus).

What things should I avoid?

If you are allergic to a type of shellfish, you should avoid eating that type of shellfish. In addition you should avoid foods that may have been contaminated with or have come into contact with shellfish.

Is cross contamination a concern?

Many foods are inadvertently contaminated with shellfish during their processing or preparation. Any foods prepared in a facility that handles shellfish are at risk for being contaminated.

How and when can I reintroduce shellfish?

You should consult with your physician regarding when and how to reintroduce shellfish into you or your child’s diet. Your physician may use skin or blood tests to determine if it is safe to reintroduce shellfish into the diet.

Is my child allergic to all shellfish and fish?

Many individuals with a shellfish allergy may tolerate some types of shellfish and be allergic to others. You should check with your healthcare provider to determine which shellfish are safe to eat. Although it is possible to be allergic to shellfish and fish, this is uncommon as the proteins that cause allergy in fish are unrelated to those found in shellfish.

Is it safe to breast-feed my child?

Breast-feeding is generally safe in children with shellfish allergy if the mother avoids foods containing shellfish.

If I am allergic to shellfish do I need to avoid iodine as well?

Shellfish allergy is due to proteins in the shellfish and is unrelated to iodine sensitivity. People with shellfish allergy are not believed to be at increased risk for reactions to iodine containing products.
