Fish and Shellfish Allergies

In most cases, fish and shellfish allergies do not present until adulthood, meaning that many kids can grow up eating – and even liking – seafood products before becoming allergic later in life. Shellfish in particular can cause severe allergic reactions, meaning it is always a good idea to have an epinephrine auto-injector on hand to treat any allergic reactions.

Following these guidelines can help with preventing an allergic reaction to fish and shellfish.

Fish and Shellfish Allergies Guidelines

  • 1 Most people who are allergic to one type of fish or shellfish are allergic to many other kinds as well.
  • 2 Even steam from cooking fish and shellfish can cause an allergic reaction.
  • 3 Food labels are required to list the type of fish or shellfish that is used in the product.
  • 4 Many sauces can contain seafood or seafood products, including Caesar salad dressing, Worcestershire sauce, BBQ sauce, and others.
  • 5 Given the strength of allergic responses, cross-contact is a severe worry, so avoid seafood restaurants or even standard restaurants with a significant seafood menu.
  • 6 Many ethnic restaurants are likely to use fish and shellfish ingredients.

Fish and Shellfish Allergies Checklist

  • Read all food labels to avoid foods that may contain fish or shellfish.
