Fish allergy is a type of allergy that can cause very severe reactions. Hives, vomiting, stomach pains and diarrhea, anaphylactic shock with circulatory collapse, and severe asthma attacks are different reactions that can occur in fish allergy. For the most sensitive allergy patient, it is enough to feel the fish smell of suffering an asthma attack.
Individuals with fish allergy are generally advised to avoid all species of fish unless a specific species has been tested and can be tolerated by the individual. The allergic protein in fish is usually cross-reactive among all fish. Oral allergy syndrome is the most common sign of fish allergy. This allergy causes the tongue to immediately tingle after eating fish.
For a fish allergy person, it is imperative to always carefully read the contents of all pre-produced food, as there are several types of food products that are protein-enriched with fish protein. There are also feed enriched with fish protein, which makes the meat from an animal that was bred on such feed can contain sufficient amounts of fish allergen to trigger symptoms in most fish allergic individuals.
Sometimes people suffer from allergy-like reactions when they eat herring or tuna. This need not be an allergy but a reaction to the high level of histamine present in certain fish. These reactions may manifest as troublesome rash, headache and stomach pain.
