Salmon allergy is a form of fish allergy that can occur after eating any kind of finned fish products. There is no reason to get scared though. You can identify the symptoms and take adequate precautions once you learn how to deal with it. Read on to find more…


Reasons for Salmon Allergy

The proteins present in fishes with fins can trigger off allergic reactions in our body. Consuming salmon, tuna or cod might turn out to be an unpleasant experience for us when our body identifies the fish proteins as harmful substances and tries to get rid of them. The chemical, histamine as well as the antibody IgE try to eliminate the offending proteins and our body experiences various symptoms that are painful as well as discomforting.

The allergic reactions to salmon is not an isolated incidence, similar reactions are bound to occur on consumption of other finned fishes although being allergic to shellfishes along with finned fishes cannot be a foregone conclusion. Molusc and shellfish allergies may occur as a cross reactivity but each of the allergens need to be confirmed by specific tests.

Inhalation of the fishy smell or touching the flesh of a salmon may cause the allergy to flare up too.


Salmon Allergy Symptoms

The symptoms of the fish allergy are evident within minutes of ingesting the food and a delay of more than 24 hours  for noting the allergic symptoms is very rare indeed. The common symptoms include:-

  • Inflammation of the facial area, mouth and oral cavity
  • Intense skin itching and redness of the skin with appearance of hives.
  • A feeling of bloating, nausea, flatulence, and acid reflux.
  • Stomach cramps and vomiting along with diarrhea
  • Sneezing, runny nose and sinusitis
  • Tingling of the skin
  • Persistent coughs and difficulty in breathing
  • Chocking of the throat leading to lightheadedness and loss of consciousness.


Diagnosis of Salmon Allergy

  • Prick Test- The allergen in the form of fish is injected in the skin and the reaction observed.
  • RAST – A blood sample take from the patient is tested for the presence of IgE.
  • Cross reactivity- Allergy tests for other related allergens especially those present in shellfishes and molluscs are also conducted on the patient.
  • Parasite Tests- The parasite Anisakis simplex lives within the fishes and can often trigger severe allergic reactions. The diagnosis will remain incomplete unless the patient is tested for the parasite allergy.


 Treating Salmon Allergy Symptoms

  • Avoiding all kinds of finned fishes along with shell fish and mollusks is a prerequisite for treating fish allergies.
  • Skin lotions with corticosteroids help to reduce skin rashes and inflammations
  • Asthmatic  medicines can help to overcome the tingling feeling and itching all over the body.
  • Nasal sprays and eye drops control the common cold like symptoms
  • Epinephrine injections become essential when the allergy becomes severe and interferes with normal breathing and causing the blood pressure levels to fall.


It is important to remember that you might not actually have salmon allergy if you feel sick after eating the fish. Rotten fish or improper cooking may cause food poisoning symptoms which are similar to the allergic reactions. It is, therefore, best to observe carefully and visit your doctor as soon as you feel that something is wrong.
