Crucial Facts Concerning Shellfish Allergy

By Tonci Vulin


Throughout the US, any adults are experiencing allergies that are caused by eating shellfish. Roughly two percent of American adults have a shellfish allergy, and 0.1 percent of children have a shellfish allergy.

It is during adulthood that shellfish allergies are likely to develop. Shellfish allergies tend to be severe, lifelong food allergies.

What are the Typical Signs and Symptoms of Shellfish Allergy Symptoms of shellfish allergy generally appear within minutes up to two hours of eating shellfish. Symptoms can include: Skin reactions such as hives or eczema. Group of reactions like watering of eyes, itchiness and redness is called allergic conjunctivitis. GI reactions like nausea, abdominal pain, vomiting, or diarrhea. Wheezing, runny nose and coughing are also respiratory symptoms that are brought on by allergy.

Your lips will swell and also your tongue and face. These symptoms are classified as angioedema. Severe anaphylaxis is the severe symptom of shellfish allergy. Anaphylaxis is a medical emergency that needs prompt medical attention. Shellfish allergy is the most typical causes of Exercise-Induced Anaphylaxis, in which the combination of eating a food allergen and exercising triggers anaphylaxis. What's with Shellfish that triggers Allergies

Mollusks and Crustaceans are two main families of the shellfish origin. Oysters, squids and clams are under the family of mollusks. While lobsters, shrimps and crayfish are under the family of crustaceans. Shellfish may live in fresh or salt water - or perhaps on land.

People who are allergic to one kind of crustacean, such as shrimp, are usually allergic to all other crustaceans. If you are allergic to crustaceans, you may or may not be able to eat mollusks like clams or oysters. You can still eat shellfish so long as you have gone through an allergy testing.

The allergenic protein in shellfish (tropomyosin) isn't just present in sea creatures. Individuals with shellfish allergies may also have reactions to land snails, dust mites, cockroaches, or other insects.

Living With a Shellfish Allergy You need to avoid shellfish or make preparations prior to allergic reactions because there is no known remedy for shellfish allergy to date. You have to carry an emergency medication known as epinephrine auto-injector (commonly called an Epi-Pen) which is normally prescribed by the physicians. Remember that food allergens can be present in almost all food items. You will need to learn to read labels to prevent shellfish, and learn to ask questions when you eat in dining places. Shellfish and Labeling Laws: The Food Allergy Labeling Law (FALCPA) defines crustacean shellfish as one of the huge eight allergens, but not mollusks. This signifies that manufacturers are not required to list the presence of clams, oysters, mussels, scallops or other mollusks in ingredient lists.

Mollusks have wide selection of shellfish types so if you are allergic to crustacean shellfish, its likely to be allergic to other types. Allergy testing can help you determine if mollusks are safe for you to eat.

You should always read ingredient labels very carefully if you have shellfish allergies. Allergy to Iodine Products and Shellfish A lot of medical sources wrongfully document that there is a cross-reactivity between iodine/contrast allergy and shellfish allergy. Radiocontrast materials are iodine-containing products and they don't have to be avoided if you have shellfish allergy. It is possible to be allergic to iodine or radiocontrast material, but those allergies are not linked to shellfish allergies, so you do not need to fret about cross-reactions.

Shellfish Poisoning Shellfish poisoning is also known as Red Tide and Paralytic Shellfish Poisoning. You might mistake yourself with the symptoms of shellfish poisoning for an allergic attack as it normally erupts within 30 minutes after ingestion of spoiled shellfish. Saxitoxin is a powerful toxin that mainly triggers shellfish poisoning. This toxin is released by algae organisms seen in the molluscs, clams and oysters. As such, this kind of toxin only affects mollusks, and not fish or lobster. Tingling or burning feeling in the mouth or extremities, nausea, vomiting, and diarrhea are the usual allergy symptoms of this shellfish poisoning. Shellfish poisoning can be very serious or even deadly. If you have any of these symptoms after eating shellfish, get emergency medical care.
