Learn which foods your child should avoid if they have a seafood allergy and how you can help your child manage their allergy.

Key points

  • Seafoods include fish, crustaceans and molluscs. A seafood allergy can be different for each person: some people can eat one complete type of seafood but cannot eat another. Other people can tolerate some crustaceans, for example, but not others.
  • Most children with a seafood allergy do not outgrow it. Consult an allergist regularly to see if there is any change in your child's allergy.
  • Sources of seafood include coffee, fried rice, salad dressing and gelatin.
  • To prevent an allergic reaction, always read food product labels, avoid foods if you are not sure of the ingredients and avoid using utensils or containers that might have come in contact with seafood.
  • If your child's diet is limited because of a seafood allergy, a registered dietitian can offer advice on getting a balanced diet.
