Is it possible to be allergic to salmon




















Read food labels carefully. Treat symptoms of anaphylaxis with epinephrine adrenaline. Symptoms As with other food allergies, the symptoms of a fish allergy may range from mild to severe. Management and Treatment Managing a fish allergy includes strict avoidance of the fish to which you are allergic.

Weaker inhibition was seen with pollock roe and with salmon extract. No inhibition was seen with hen's egg. Immunoblotting showed IgE binding to salmon roe at 15 and 17 kDa with the sera from the patients who had reacted.

The third patient's sera bound to a 21 kDa band. N-terminal sequences suggested that all the bands were fragments of vitellogenin. The 15 and 17 kDa bands were from the beta'-component while the 21 kDa band may have been lipovitellin. Untersmayr et al. This patient's serum contained IgE binding to bands at masses of 30, 84, , and kDa from sturgeon caviar and less intense IgE binding to a kDa band in lumpsucker and an kDa band in trout and salmon caviars.

These authors also suggest that the kDa protein might be vitellogenin. Lindstrom et al. Bugajska-Schretter et al. Van Do et al [ ] used SPT and ELISA inhibition with 12 patients and their sera to characterize the cross-reactivities of native and some recombinant parvalbumins from 9 species with cod.

For most sera, both native and recombinant salmon parvalbumins caused significant inhibition of IgE binding to cod parvalbumin. Parvalbumins control the flow of calcium from troponin C back to membrane bound pumps after a muscle contraction. Each parvalbumin can bind two calcium or with lower affinity magnesium ions.

Most fish beta-parvalbumins are acetylated at the N-terminus and Lingstrom et al [ ] reported that the N-terminus of salmon parvalbumin was blocked. Van Do et al [ ] report production and purification of both parvalbumins as recombinant His-tag fusion proteins using an Escherichia coli expression vector pETb. The His-tag could be partially removed by digestion with enterokinase.

The proteins without the His tag showed a MW similar to that of the native protein. Longer digestion or a larger enterokinase concentration led to further degradation of the proteins. There are two families of beta-parvalbumin sequences in several fishes. Skip to main content Skip to navigation Skip to Search. Smoked salmon is likely to have allergenic properties similar to ordinary fish. Canned salmon may have reduced allergenicity as is found with tuna.

Allergy Information: Allergy to fin fish is relatively common 0. Supplementary information on Fish Allergy Fish and fish products play an important role in human nutrition. Other proteins in fish have been described as allergens, but most reactions to cod and other fish; see under Related foods are most likely caused by this one allergen Symptoms Reactions can be severe and even life-threatening.

Related foods cross-reactions Most information on fish allergy is gathered on codfish. Who, when, how long and how often? How much is too much? Diagnosis An indication for IgE-mediated fish allergy can be obtained from skin prick testing and from serum IgE testing. Where do I find fish? Non-food products Fish gelatine is applied in pharmaceutical products like vaccines, but it is not considered a risk to fish allergic persons. Avoidance If suffering from fish allergy, strict avoidance of fish in any form and food containing fish-derived ingredients is the only way to prevent a reaction.

Clinical History Number of Studies: Number of Patients: Symptoms: Most articles mentioning allergy to salmon describe allergy to fish in general without attributing symptoms specifically to salmon. Protocol: controls, definition of positive etc Helbling et al.

Number of Patients: Helbling et al. In one study, salmon, tuna, catfish and cod were the fish to which people most commonly reported allergic reactions. Finned fish and shellfish are not closely related. Being allergic to one does not always mean that you must avoid both, though care is needed to prevent cross-contact between fish and shellfish. Discuss this issue in detail with your allergist to make sure the appropriate food restrictions are implemented. 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. To prevent a reaction, it is very important to avoid all fish and fish products.

Always read food labels and ask questions about ingredients before eating a food that you have not prepared yourself. Steer clear of seafood restaurants, where there is a high risk of food cross-contact. You should also avoid touching fish and going to fish markets. Being in any area where fish are being cooked can put you at risk, as fish protein could be in the steam. More than half of people who are allergic to one type of fish are also allergic to other fish.

Fish is one of eight allergens that must be listed on all food ingredient labels under the Food Allergen Labeling and Consumer Protection Act of If your allergy symptoms are mild, you can often treat them with an over-the-counter oral antihistamine. If you are at risk of a severe reaction, you may be advised to carry a single-use, pre-filled epinephrine injector, such as an EpiPen , which you would inject into your thigh in case of an emergency.

Unlike other forms of allergy, food allergies cannot be treated with allergy shots immunotherapy. While a fish allergy may be less common than a seafood or nut allergy , it can be every bit as serious.

To this end, you should take steps to protect yourself if you have been diagnosed with a fish allergy. While some allergies can be annoying, others can be downright deadly.

If you have had anaphylaxis in the past or are at risk, consider wearing an emergency medical bracelet outlining your condition, recommended treatments, and drugs to avoid. In this way, if you are unconscious or unable to reply, the emergency medical team can take appropriate action without losing precious time.
