Shellfish Allergy Diet

General guidelines for shellfish allergy

The key to an allergy-free diet is to avoid giving your child the foods or products containing the food to which he or she is allergic. The items to which your child is allergic are called allergens.

A shellfish allergy is an abnormal response of the body to the proteins found in shellfish. In order to avoid foods that contain shellfish proteins, it is important to read food labels.

How to read a label for an shellfish-free diet

Be sure to avoid foods that contain any of the following ingredients:

  • Abalone
  • Clam (cherrystone, littleneck, geoduck, pismo, quahog)
  • Cockle, periwinkle, sea urchin
  • Crab
  • Crawfish, crayfish, ecrevisse
  • Cuttlefish
  • Limpet (lapas, opihi)
  • Lobster, langouste, langousine, scampo, coral, tomalley
  • Molluscs
  • Mussels
  • Octopus, squid (calamari)
  • Oyster
  • Scallops
  • Sea cucumber (often used in Asian soups)
  • Shrimp, prawns, crevette
  • Snail (escargot)
  • Whelk (turban shell)

The following foods may indicate that shellfish protein is present:

  • Bouillabaisse
  • Cuttlefish ink
  • Fish stock
  • Glucosamine
  • Seafood flavoring
  • Surimi

Any food--even a non-seafood item--that is made in a seafood restaurant could be cross-contaminated with fish or shellfish.

Some fish-allergic individuals may react to cooking odors or from touching shellfish or fish.

Use caution when eating in Asian restaurants. Fish sauce is often used as a flavor enhancer.

Shellfish protein can become airborne in the steam released during cooking. Avoid steam tables or buffets where seafood is displayed and served.
