Fish allergy (finned fish) affects about 1.0 percent of the population1. Fish allergy tends to be life-long and is more common in adults than children.
Those who are allergic to finned fish can usually tolerate crustaeans and/or molluscs but care must be taken because of the real risk of cross contamination in storage, preparation and cooking of the seafood. Occasionally people have breathing difficulties from smelling fish being cooked. Most people who have a fish allergy are advised to not have fish cooked in their home because of the risk of the smell triggering a serious allergic reaction.
Please note: If you are allergic to fish, you are at high risk of being allergic to crocodile meat.
