Fish

Up to 7% of individuals might experience fish allergies. Similar to other allergies, fish allergies frequently appear in children. However, it's not unusual for a seafood allergy to develop in later life. A fish allergy can result in a significant and even deadly allergic response, similar to a shellfish allergy. Vomiting and diarrhea are the predominant symptoms, however, anaphylaxis can also happen on occasion. As a result, individuals with fish allergies are frequently given epinephrine auto-injectors to carry just in case they consume fish unintentionally.

A fish allergy can occasionally be mistaken for a response to a fish contaminant, such as germs, viruses, or toxins, due to the similarity of the symptoms. Furthermore, those who are sensitive to shellfish could not also be allergic to fish since fish with fins and fish with shells do not have the same proteins. But many individuals with fish allergies are also allergic to one or more fish species.
