Know what U.S. labels must name
Crustacean shellfish is a major U.S. food allergen. FDA-regulated labels must identify the species, such as crab, lobster, or shrimp, when it is used as an ingredient.
Restaurants need a conversation
Recipes, broths, sauces, fryers, grills, and preparation tools may create exposure that is not visible on a menu.
- Name the specific shellfish you avoid
- Ask about stocks, sauces, and shared fryers
- Confirm preparation with the person responsible
- Follow your emergency plan
Do not rely on a scan alone
This guide is educational. Shellfish is not presented here as a confirmed built-in profile option in Allergy Scanner, and an app result cannot establish that a meal is safe.
