The Food Allergen Labeling and Consumer Protection Act of 2004 (FALCPA) requires the identification of Crustacean shellfish, among other allergies. There’s often confusion about what species are considered a Crustacean shellfish.
Shellfish have two groups, crustaceans, and mollusks/bivalves. An allergy to crustaceans is more common, requiring identification by the FDA. FALCPA does not require the identification of mollusks and bivalves.
Common crustaceans requiring identification:
- Crab
- Crayfish
- Lobster
- Shrimp
- Prawns
Common mollusks and bivalves where identification is not required:
- Abalone
- Clams
- Mussels
- Octopus
- Oysters
- Scallops
- Snail
- Squid
Finned fish is another allergy that requires identification, but it’s not to be confused with crustacean shellfish. Go here for more information on the major allergies identified by the FDA.
