Does shellfish allergy include all types of shellfish?

Not always. Some people react only to crustaceans (prawns, crab, lobster) and not molluscs (mussels, clams), or vice versa. Customise your allergy card to reflect exactly which types you must avoid.

Can I eat in a seafood restaurant with a shellfish allergy?

It depends on the restaurant's ability to prevent cross-contamination. Present your allergy card before ordering so staff can advise whether they can safely accommodate you.

Can shellfish allergy appear suddenly in adults?

Yes. Shellfish allergy commonly develops in adulthood with no prior history. If you have been diagnosed, carrying an allergy card helps you manage the adjustment safely.

Shellfish allergy is one of the most common food allergies in adults and often causes severe reactions. It covers crustaceans such as prawns, crab, and lobster, as well as molluscs like mussels and oysters. A shellfish allergy card helps you communicate your needs in restaurants and other food settings.

Hidden Sources of Shellfish

Shellfish extracts and derivatives can appear in unexpected products. Fish sauce, oyster sauce, and shrimp paste are widely used in Asian cooking. Some glucosamine supplements are made from shellfish shells. Cross-contamination is a significant risk in seafood restaurants, fish counters, and paella or bouillabaisse-style dishes where shellfish stock is the base.

How a Shellfish Allergy Card Helps

Because shellfish reactions can be rapid and severe, clear communication is critical. A card ensures kitchen staff know your allergy before preparation begins, not after. It also prompts them to consider cross-contamination from shared pans, fryers, and utensils - risks that are easy to overlook in a busy kitchen.

When to Use Your Shellfish Allergy Card

Carry your card at any restaurant, particularly seafood, Asian, and Mediterranean venues. Buffets and food markets are higher risk due to shared serving utensils. When travelling to coastal regions or countries where shellfish is a dietary staple, a translated card is essential for safe eating.
