Crustaceans have jointed legs, a hard shell and a backbone. Crustaceans include crabs, lobster, prawns and shrimp, crayfish, and yabbies.
An allergy to seafood affects approximately 1% of the population. It is usually life long and is more common in adults than in children.
People who are allergic to crustacean can usually tolerate finned fish but care must be taken because of the real risk of cross contamination in storage, preparation and cooking of the seafood.
Occasionally people with crustacea allergy have breathing difficulties from crustacea being cooked in the same enclosed space they are in. Most people who have a fish or crustacean allergy are advised to not have that food cooked in their home because of the risk of the smell triggering a serious allergic reaction.
