What is a finned fish allergy?
A fish allergy, as opposed to a shellfish allergy, is one in which your immune system reacts abnormally to a finned fish such as tuna, halibut, or salmon. It is a somewhat less common form of food allergy, affecting women more than men and adults more than children.
Can you suddenly become allergic to fish?
Adults and young adults may suddenly develop a shellfish allergy; it can appear at any age. They may never have had an allergic reaction to shellfish or seafood before, and suddenly have a severe reaction to shellfish.
What protein causes fish allergy?
Parvalbumin has been defined as the major fish allergen as a majority of fish-allergic patients have IgE antibodies reacting to this muscle protein (63–65).
Can a fish allergy go away?
Fish allergy can develop at any age. Even people who have eaten fish in the past can develop an allergy. Some people outgrow certain food allergies over time. But those with fish allergies usually have that allergy for the rest of their lives.
Can fish allergy be cured?
Management & Treatment While there is no fish allergy cure, there are several fish allergy treatments that can help you manage your condition.

How do you treat a fish allergy?
Because fish is often implicated in cases of food-induced anaphylaxis, allergists advise fish-allergic patients to treat symptoms of a reaction with epinephrine (adrenaline), which is prescribed by your doctor and administered in an auto-injector.
How do you treat fish allergy?
There’s currently no cure for a shellfish allergy. The best treatment is to avoid foods such as shrimp, lobster, crab, and other crustaceans. Finned fish are not related to shellfish, but cross-contamination is common. You may want to avoid seafood altogether if your shellfish allergy is severe.
Does fish allergy go away?
How are finned fish related to food allergy?
When a person with an allergy to a particular fish is exposed to that fish, proteins in the fish bind to specific IgE antibodies made by the person’s immune system. This triggers the person’s immune defenses, leading to reaction symptoms that can be mild or very severe. Finned fish and shellfish are not closely related.
What to do if you have an allergy to fish?
Finned fish can cause severe and potentially life-threatening allergic reactions (such as anaphylaxis). Allergic reactions can be unpredictable, and even very small amounts of fish can cause one. If you have a fish allergy, keep an epinephrine injection device with you at all times. Epinephrine is the first-line treatment for anaphylaxis.
Which is the most common type of fish to be allergic to?
More in Food Allergies. Fish allergy tends to be a lifelong allergy, with about 40% of people with fish allergy experiencing their first reaction as an adult. The most common kinds of finned fish causing an allergic reaction are salmon, tuna, and halibut, although other fish such as Pollock, cod, snapper and eel are also common.
How are fish allergies related to polysensitization?
The primary allergen responsible for a fish allergy is a protein known as parvalbumin. 3 Parvalbumins vary little between different fish species, meaning that an allergy to one fish will usually result in an allergy to other fishes (a condition known as polysensitization).
