Seafood allergy occurs to an individual whose body's immunity system responds to the proteins found in specific marine animals.
Seafood comprises shellfish, such as shrimps, mussels, octopus, lobster, crab, squid, clams, and finned fish such as mackerel, tuna, salmon, cod, and sardines.
Are you suffering from an allergy to any of these seafood? If yes, dedicate your next few minutes to reading this article as it summarises the vital aspects of seafood allergies.
Seafood comprises both shellfish and finned fish; however, they differ biologically. Therefore, if you suffer from an allergy to finned fish, that does not imply that you may be allergic to shellfish. Moreover, the crustaceans within the shellfish group, such as prawn, crab, crayfish, lobster, etc., cause more allergies than molluscs, including octopus, oysters, snails, etc.
However, whether you suffer from shellfish allergy or you are allergic to fish, identify the following symptoms, which are common for both these allergies, and report to a doctor immediately:
The symptoms mentioned above may differ with each seafood. For example, crab allergy and prawn allergy symptoms include itching or tingling sensation in and around the mouth. Additionally, symptoms may vary with each individual.
Allergies to fish or shellfish may cause anaphylaxis in rare cases. This severe medical condition demands immediate medical attention.
If you are suffering from severe prawn allergy or is allergic to any other seafood, look for the following symptoms of anaphylaxis to remain aware beforehand:
These are the common symptoms that you may find in the symptoms of shrimp allergy or allergies to other seafood. However, this may worsen. So, contact your nearest clinic if you or your close ones meet such a severe medical condition to avoid fatal consequences.
In every allergy, the immunity system of your body responds to allergens. Your body generates antibodies to identify the allergens, causes inflammation and produces a chemical known as histamine, which causes allergic symptoms such as hives. In addition, there are specific molecules in fish or shellfish that may be available in other foods, and you may suffer from allergies from those foods containing that molecule.
For example, you may suffer from an allergy to a specific fish or may be allergic to multiple crustaceans such as prawns, lobster and crab. This is called cross-reactivity and is difficult to diagnose. Therefore, consult a doctor if you suffer from such a condition.
Allergies to seafood, including fish and shellfish, may last for an entire lifespan. If you suffer from allergic symptoms from seafood, contact a doctor. He or she may refer you to a clinical immunologist or an allergist.
An allergist may perform the following test depending upon the type of allergies:
If you have an allergy to a particular fish type and are willing to consume other types of seafood available in the market, you may ask the specialist to perform allergic tests for other kinds of fish.
If you suffer from severe symptoms of crab allergy or exhibit other allergic symptoms to seafood, the doctor may prescribe you an antihistamine. This reduces swelling, hives, and other skin rashes, if any. However, if you meet a severe condition like anaphylaxis, you may be treated with epinephrine.
If you are at risk of developing anaphylaxis, a healthcare professional may prescribe you to keep injectable epinephrine always with you. In addition, he or she may recommend you to administer epinephrine even if your body displays symptoms of seafood allergy for the first time as a precautionary measure

Take a look at the list of fishes that may trigger your allergic symptoms caused by fishes:
Here is the list of shellfish that you must avoid that may aggravate your allergic reaction to prawns or other shellfish:
When eating at a restaurant, check that the utensils utilised for cooking seafood are not used for cooking other food dishes. This is why it is ideal to avoid dining out at a restaurant that specialises in seafood. Additionally, avoid sharing plates with those consuming seafood to prevent cross-contamination.
Additionally, avoid visiting places where the seafood is processed or prepared. Inhaling the vapour from the cooked seafood may cause a respiratory reaction among selected individuals with seafood or shellfish allergy symptoms.
Home remedies for prawn allergy or other shellfish allergies may naturally calm down the allergic symptoms. Adding foods like yoghurt, vitamin C-rich foods such as oranges and broccoli, foods and drinks like ginger and green tea to your diet may help with seafood allergies. However, in severe allergic reactions, contact a doctor without any delay.
Insufficient knowledge about seafood allergies may cause panic. Hence, carefully go through the information mentioned above if you suffer from a seafood allergy. Alternatively, consult a doctor to know more details about it.
