What is an Shellfish Allergy?

A shellfish allergy occurs when the body’s immune system mistakenly identifies proteins in shellfish as a threat. Proteins in the shellfish bind to specific IgE antibodies produced by the immune system. When this happens, the body releases chemicals, including histamine, leading to symptoms that range from mild to severe, and can be life-threatening.

Shellfish allergy can develop at any age, including in babies and toddlers. However, it is more common in adults. In fact, about 60% of people with shellfish allergies experience their first reactions as adults.

The good news is that you can live a safe, fulfilling life with proper care and management. Our board-certified food allergy specialist and team at Safe2Bite offer food allergy care across the Metroplex, managing severe allergies with skill and expertise. We are the go-to clinic when it comes to managing severe allergies in North Texas and beyond.

What Is the Difference Between Crustaceans and Mollusks?

Shellfish come in two groups: crustaceans and mollusks. Crustaceans typically have hard, segmented exoskeletons and jointed limbs. They include crabs, lobsters, shrimp, prawns, crayfish, barnacles, and krill. Mollusks, on the other hand, have soft, unsegmented bodies. They include octopus, clams, oysters, squid, mussels, and scallops.

In general, people who react to one type of shellfish are likely to be allergic to others in the same group. For example, if you are allergic to shrimp, you will likely react to other crustaceans. Many people who are allergic to crustaceans can eat mollusks with no problem. However, it’s always advisable to consult with your food allergist before consuming any other type of shellfish.

How Are Shellfish Allergies Diagnosed?

A history of allergic reactions soon after shellfish exposure is a clear sign of a shellfish allergy. However, testing is the only conclusive way to diagnose a food allergy. Our board-certified food allergist may recommend one or a combination of the following:

How Are Shellfish Allergies Diagnosed?

A history of allergic reactions soon after shellfish exposure is a clear sign of a shellfish allergy. However, testing is the only conclusive way to diagnose a food allergy. Our board-certified food allergist may recommend one or a combination of the following:

Skin Prick Testing (SPT)

This involves pricking small amounts of shellfish proteins into the skin on the arm or upper back. If you’re allergic, raised bumps or redness should appear in 15 to 20 minutes.

Blood Testing

This test determines the immune system’s response to a specific allergen by measuring the amount of shellfish-specific antibodies in the bloodstream, known as immunoglobulin E (IgE).

Oral Food Challenge (OFC)

If the diagnosis is unclear after skin prick tests and blood testing, we may recommend a supervised oral food challenge. This involves ingesting gradually increasing amounts of the suspected shellfish under strict medical supervision to monitor for signs of allergic reactions.

What Are the Treatment Options for Shellfish Allergies?

Depending on your unique needs, our food allergy specialist may recommend one or a combination of the following treatments to help build tolerance to shellfish:

Oral Immunotherapy (OIT)

OIT involves introducing gradually increasing doses of the allergen in the mouth under strict supervision by our team. The goal is to increase tolerance to the proteins in shellfish and reduce the risk of severe reactions.

Food Sublingual Immunotherapy (SLIT)

SLIT involves introducing gradually increased doses of the shellfish allergen under the tongue. This may help build tolerance over time and lower the risk of severe allergic reactions in the future.

Tips to Avoid Exposure to Shellfish When Dining Out

Dining out with a shellfish allergy can be stressful, but with the right planning and precautions, you can enjoy time with family and friends without worry. The biggest challenge patients face is cross-contamination and sauces with shellfish ingredients. Even though the dish you select may not have shellfish, it’s important to stay aware and safe.

We recommend avoiding foods like gumbo, paella, or seafood chowders, even if they don’t list shellfish as a main ingredient. More importantly, inform your server of your food allergy and have them check with the chef to ensure your meal does not contain shellfish, nor has it come in contact with it during preparation. Most chefs or restaurant managers are helpful and will answer your questions. If they cannot guarantee the safety of your dish, you may want to opt for a different restaurant.

In the unfortunate event that you are exposed to shellfish and have a severe reaction, act fast. Use your epinephrine auto-injector immediately and call 911 for assistance.
