Fish allergy is an allergy in which the body's immune system reacts abnormally to finned fish such as tuna, halibut, or salmon. This is a less common form of food allergy, affecting more women than men and more adults than children.

Fish allergy is a very common phenomenon. The symptoms of the allergy occur quickly, within minutes to hours after eating. Some cases of fish allergy can be life-threatening. Therefore, prevention or finding a way to live with fish allergy is very important.

Sea fish is a popular and very healthy food. However, many people often suffer from histamine poisoning after eating sea fish. If not treated properly, it can lead to serious allergies and even be life-threatening.
