Crayfish

Crayfish allergy is a hypersensitive reaction to proteins found in crayfish, a type of shellfish. The severity can vary from mild to severe and, at times, may pose a life-threatening risk. Individuals with a crayfish allergy might experience a reaction not only from consuming crayfish but also from inhaling the steam released during cooking.
