Shellfish Allergy: Medical Alert And Awareness

By Tonci Vulin


Shellfish allergy is the most common food allergy among adults in the United States. Approximately 2 % of American adults have a shellfish allergy, and 0.1 percent of youngsters have a shellfish allergy.

It is during the adult years that shellfish allergies are likely to develop. Shellfish allergies tend to be serious, lifelong food allergic reactions.

Symptoms of Shellfish Allergy Symptoms of shellfish allergy typically appear within minutes up to two hours of eating shellfish. Symptoms can include: Hives and eczema are a few of the typical skin allergic reactions. Allergic conjunctivitis: Itchy, red, watery eyes. GI reactions such as nausea, abdominal pain, vomiting, or diarrhea. Airways symptoms like wheezing or coughing or runny nose.

Angioedema: Swelling of lips, tongue, or face Severe anaphylaxis is the severe sign of shellfish allergy. Anaphylaxis is a medical emergency that needs prompt medical treatment. Shellfish allergy is the most typical causes of Exercise-Induced Anaphylaxis, in which the combination of eating a food allergen and exercising leads to anaphylaxis. What's with Shellfish that Causes Allergies

Mollusks and Crustaceans are two primary 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 even on land.

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

Trompomysin, an allergenic protein in shellfish, isn't only present on sea creatures entirely. People with shellfish allergies may also have allergic reactions to land snails, dust mites, cockroaches, or other insects.

Engaged To a Shellfish Allergy You have to avoid shellfish or make preparations prior to allergic reactions because there is no known treatment for shellfish allergy yet. If you have been diagnosed with a severe shellfish allergy, your physician will prescribe an epinephrine auto-injector (normally known as an Epi-Pen) that you will have to carry with you all the time. Staying away from shellfish may look uncomplicated, but food allergens can lurk in surprising places. Hence, it is essential that you read labels before buying a food item. In addition to that, you also need to ensure if the food that you are about to order in a restaurant has shellfish to avoid allergies. The Labelling Laws for Shellfish Products All mollusks doesn't result in allergies but the major allergy activating food is the crustacean shellfish which is shown as one of the big eight allergens based on the Food Allergy Labeling Law (FALCPA). The printing of labels regarding the products having clams, oysters, mussels, scallops or other mollusks is not the obligation of the manufacturer of the product.

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

For those who have recognized shellfish allergies, its best to read the content and label of the products you are buying. Allergy to Iodine Products and Shellfish There are unverified concerns of a cross reactivity between shellfish allergy and iodine/contrast allergy - some old medical types still list this wrongly as a contraindication. If you are allergic to shellfish, you do not need to refrain from iodine or radiocontrast material. Shellfish allergies aren't associated with the iodine allergy or radiocontrast substances so cross-reactions are not something you must worry about.

Shellfish Poisoning Shellfish poisoning is also called Red Tide and Paralytic Shellfish Poisoning. You might confuse yourself with the symptoms of shellfish poisoning for an allergic reaction since it normally erupts within 30 minutes after ingestion of spoiled shellfish. Shellfish poisoning is the effect of a really potent toxin called saxitoxin that is released by algae-like organisms that live in two-shelled mollusks, like clams and oysters. As such, this sort of toxin only affects mollusks, and not fish or lobster. Prickling or burning feeling in the mouth or extremities, nausea, vomiting, and diarrhea are the usual allergic symptoms of this shellfish poisoning. Shellfish poisoning is something that must not be disregarded since this could lead to life-threatening circumstances. You have to seek prompt medical treatment if you are experiencing these symptoms.
