Shellfish Allergy at Thai Restaurants
Understanding Shellfish Allergy
Shellfish allergy covers shrimp, crab, lobster, scallops, oysters, clams, and mussels. It's one of the most common adult-onset allergies and most likely to trigger severe anaphylaxis. The invisible risk is cross-contamination in restaurant kitchens where shellfish are handled on shared surfaces.
Thai Cuisine — Allergen Profile
Thai cuisine is built on a foundation of peanuts, fish sauce, shrimp paste, soy sauce, and eggs — making it one of the highest-risk cuisines for multiple allergies. The challenge is that foundational allergens appear as invisible base seasonings rather than listed ingredients. What reads as a 'vegetable curry' often contains shellfish-derived shrimp paste.
Primary allergen risks in Thai cuisine: peanuts, shellfish (shrimp paste), soy, eggs.
Shellfish Allergy + Thai: What You Need to Know
Thai cuisine is extremely high risk for shellfish allergy because shrimp paste (kapi) is a foundational seasoning ingredient in nearly every Thai dish — including curries, soups, and salads that do not list shellfish as an ingredient. Even a green curry described as vegetarian may be seasoned with shrimp paste. Fish sauce may also contain shellfish derivatives. Shellfish allergy in Thai restaurants requires asking specifically about shrimp paste in every preparation.
High-Risk Thai Dishes for Shellfish Allergy
- ✗Virtually all Thai curries (shrimp paste base)
- ✗Tom yum soup
- ✗Pad thai (dried shrimp)
- ✗Most dipping sauces
