At your appointment a detailed personal history will be taken. This will include foods you normally eat, symptoms you have experienced, how long these symptoms lasted and what, if anything, you did to treat your symptoms.\nA shellfish allergy diagnosis can sometimes be complicated as symptoms vary widely from person to person, and it is very possible for someone to have different symptoms during each reaction. Additionally, people with shellfish allergies do not necessarily have to eat it to have a reaction. They may react when other foods come in contact with shellfish during the food preparation process. Reactions often affect multiple parts of the body—skin, respiratory tract, gastrointestinal tract, and the cardiovascular system.\nIn most cases your shellfish allergy will be diagnosed by a skin-prick test or a blood test.\nThe skin-prick test will be performed in the allergist office and you can expect to have results fairly quickly—often within 15 minutes. A small spot on your forearm or upper back will be pricked with a sterile tooth pick-like stylet and drop of liquid containing the allergen will be introduced at prick site. If you have a positive reaction to shellfish you will immediately develop a small raised hive where your skin was pricked.\nFor blood tests, a blood sample is taken and tested for the presence of Immunoglobulin E (IgE) antibodies—these antibodies are produced by your body in response to a particular allergen (in this case shellfish) and results are typically available in a week to two weeks.\nShellfish Allergy Management\nThe best and only definitive treatment for shellfish allergies is strict avoidance and elimination of any foods containing shellfish from your diet. Additionally, anyone with shellfish allergies must check ingredient labels on packaged and prepared foods. You should also avoid seafood restaurants, even if you order non-shellfish containing meals it may be impossible for the kitchen to not cross-contaminate your meal.\nThe federal Food Allergen Labeling and Consumer Protection Act (FALCPA) requires all packaged food products sold in the US that contain shellfish in its ingredients, must list the specific shellfish item on the label.\nCurrently, advisory labels such as “may contain” warnings are not required to be on packages, but some companies list whether a food was produced in a facility or on equipment that comes in contact with shellfish. The absence of shellfish terms does not mean the food is safe for you though. If in doubt, contact the manufacturer and avoid the food unless you are certain it is free of allergens.\nTreatment for Shellfish Allergy Reactions\nSince food allergies are the most common causes of anaphylaxis, patients with shellfish allergies should always carry epinephrine (adrenaline) auto-injectors with them—this is the only first-line treatment for anaphylaxis. If you are not sure whether an allergic reaction is leading to anaphylactic shock, you should use the epinephrine treatment anyway—the benefits of early use outweigh the risks of an unnecessary dose.\nAdditional Steps to Take for Children with Shellfish Allergies\nSince dangerous reactions can occur at any time, it’s important that parents of children with shellfish allergies make sure family, friends, and caregivers are aware of the child’s allergy. These additional steps are important for children with shellfish and other food allergies:\nInvolve all caregivers\n: relatives, babysitters, teachers, and the school nurse need to be made aware of your child’s allergy. Emphasize with them the severity of the allergic response and ensure there are emergency supplies on hand.\nCreate written plans\n: list steps that need to be taken if a reaction occurs. Include all medications that need to be given along with dosage amounts, as well as emergency contact information of family members and family physicians and allergists.\nDo not allow your child to share foods\n: children often share their snacks and treats, ensure your child understands the dangers of sharing foods since they may contain allergens.\nPurchase a medical alert bracelet\n: to help adults and caregivers understand your child’s allergies and proper treatments in the case of emergency. This is critical if they are unable to communicate while in the midst of a reaction. The bracelet should include child’s name and specific allergy.\nAllergy Sufferers Should Also Avoid Foods Containing These Ingredients:\nBarnacle\nCrab\nCrawfish (also known as crawdad, crayfish)\nKrill and krill oil\nLobster\nPrawns\nShrimp (scampi)\nBe aware that \nmollusks\n are not considered major allergens under FALCPA and may not be disclosed on labels.

Although shellfish allergies are not as prevalent in the US as peanut allergies, they can be one of the worst allergies and sends more people to emergency rooms than any other food allergy.\n\nAs with other food allergies, an allergic reaction to shellfish can range in severity. Reactions can be mild to life-threatening leading to anaphylaxis—it’s advised that individuals with shellfish allergies always carry epinephrine auto-injectors.\n\nIt should be noted that shellfish allergies are not the same is an allergy to fish. If you are allergic to shellfish you do not necessarily have to avoid fish and fish allergy sufferers may not be allergic to shellfish.\n\nTypically a shellfish allergy is lifelong and approximately 60 percent of shellfish allergy sufferers did not have a reaction until they were an adult.\n\nThe most common causes of shellfish allergy are from shrimp, crab, and lobster. As stated above, finned fish are not in the same biological family as shellfish and allergy to one does not always mean an allergy to the other.\n\nThere are two kinds of shellfish sufferers must be aware of: crustaceans (shrimp, lobster, crab, etc.) and mollusks (clams, mussels, oysters, and scallops)—reactions to crustaceans tend be the most severe. People tend to tolerate mollusks much better than crustaceans.\n\n## Shellfish Allergy Symptoms and Diagnosis\nWhen a person has a shellfish allergy, they may exhibit the following signs and symptoms within a short period of consuming shellfish:\n\n- Vomiting and upset stomach or gastrointestinal discomfort\n- Diarrhea\n- Hives (urticaria) all over the body\n- Itching\/numbness in and around the mouth or throat\n- Swelling of the tongue and lips\n- Dizziness and confusion\n- Tightening of the throat or feeling of being unable to breath\n- Nonproductive cough\n- Pale skin\n- Anaphylaxis—a life-threatening reaction that can lead to shock, and death in extreme cases.\n\n**If you or your child have an anaphylactic reaction call 911 or seek emergency medical care immediately.**\n\nIf you suspect you have a shellfish allergy or you’ve had any of the above symptoms after eating shellfish, make an appointment with your allergy specialist as soon as possible.

These symptoms typically occur within minutes to two hours after consuming shellfish or coming into contact with shellfish proteins.\n\n[Which types of shellfish can cause allergic reactions?]()[*Expand*]()\n\nVarious types of shellfish can cause allergic reactions in individuals with shellfish allergies. The most common culprits are crustaceans such as shrimp, lobster, crab, and crayfish. Additionally, mollusks like clams, mussels, oysters, scallops, and squid can also trigger allergic responses.\n\nIt's important for individuals with shellfish allergies to avoid all forms of shellfish to prevent allergic reactions.\n\n[Can you be allergic to some shellfish and not others?]()[*Expand*]()\n\nIt is possible to be allergic to certain types of shellfish and not others.\n\nShellfish allergies can be specific to crustaceans (such as shrimp, lobster, crab) or mollusks (such as clams, mussels, oysters). This means that an individual may be allergic to one category of shellfish but not the other.\n\n[Can shellfish allergies develop later in life?]()[*Expand*]()\n\nShellfish allergies can develop later in life, even if a person has previously consumed shellfish without any adverse reactions. While allergies commonly develop in childhood, it is not uncommon for adults to develop allergies to shellfish or other foods.\n\nThe severity of the allergic reaction does not necessarily correlate with the age of onset. Shellfish allergies can be serious and potentially life-threatening, regardless of when they develop. It is crucial for individuals who suspect they have developed a shellfish allergy to seek medical evaluation and take necessary precautions to avoid exposure to shellfish proteins.\n\n[How is shellfish allergy diagnosed?]()[*Expand*]()\n\nA shellfish allergy can be diagnosed through a combination of medical history, physical examination, and allergy testing. An allergist will review a patient's symptoms, potential triggers, and any previous allergic reactions.\n\nAllergy testing, including skin prick tests or blood tests, can help identify specific shellfish allergens. If you suspect a shellfish allergy or have experienced allergic reactions after consuming shellfish, it is essential to consult with an allergy specialist for proper evaluation, diagnosis, and personalized management strategies.\n\n[Contact Jax Allergy](https:\/\/www.jaxallergy.com\/contact\/) today to schedule an appointment and get the expert care you need.\n\n[What is the recommended treatment for a shellfish allergy?]()[*Expand*]()\n\nThe recommended treatment for a shellfish allergy involves strict avoidance of shellfish and any foods or products containing shellfish ingredients.\n\nIn case of accidental exposure or an allergic reaction, immediate administration of an epinephrine auto-injector (such as an [EpiPen](https:\/\/www.jaxallergy.com\/patient-education\/)) is crucial to counteract [severe symptoms and anaphylaxis](https:\/\/www.jaxallergy.com\/allergy-treatments\/anaphylaxis\/). It is also important for individuals with shellfish allergies to carry and know how to use their epinephrine auto-injector at all times.\n\nFollowing an allergic reaction, seeking medical attention is essential for further evaluation and management.\n\n[Are there any cross-reactivities between different types of shellfish?]()[*Expand*]()\n\nYes, cross-reactivities can occur between different types of shellfish. Individuals allergic to one type of shellfish, such as shrimp, may also experience allergic reactions to other crustaceans like crab or lobster. Similarly, some individuals with a shellfish allergy may also be sensitive to certain mollusks, although the cross-reactivity is less common.\n\nIt is important for individuals with shellfish allergies to be cautious and avoid all types of shellfish to prevent potential allergic reactions.\n\n[Can shellfish allergies be outgrown over time?]()[*Expand*]()\n\nShellfish allergies are generally considered lifelong allergies, and it is less common for individuals to outgrow them compared to other food allergies like milk or egg allergies. However, in some cases, children may outgrow shellfish allergies as they get older.\n\nIt is important for individuals with a shellfish allergy to undergo proper evaluation and testing to determine if they have outgrown the allergy before reintroducing shellfish into their diet.\n\n### REQUEST AN APPOINTMENT\n# Fill Out The Form or Call Today\\!\n\n### NEED OUR SERVICES?\n# View our allergy shots and testing page for hours and more information.\n\n[Go There Now](https:\/\/www.jaxallergy.com\/allergy-shots-and-testing\/)\n\n[![Screenshot\\_2-removebg-preview](data:image\/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSI0NDYiIGhlaWdodD0iMTU1IiB2aWV3Qm94PSIwIDAgNDQ2IDE1NSI+PHJlY3Qgd2lkdGg9IjEwMCUiIGhlaWdodD0iMTAwJSIgc3R5bGU9ImZpbGw6I2NmZDRkYjtmaWxsLW9wYWNpdHk6IDAuMTsiLz48L3N2Zz4=)](https:\/\/www.jaxallergy.com\/)\n\nWe specialize in the complete care of both adults and pediatric allergy, asthma and sinus conditions.\n\nWe specialize in the complete care of  \n both adults and pediatric allergy,  \n asthma and sinus conditions.\n\n[Allergy and Asthma Specialists of North Florida Facebook page](https:\/\/www.facebook.com\/jaxallergy)     [Allergy and Asthma Specialists of North Florida Twitter page](https:\/\/mobile.twitter.com\/Jaxallergy)     [Allergy and Asthma Specialists of North Florida Youtube channel](https:\/\/www.youtube.com\/user\/jaxallergy\/featured)\n\n### Navigation\n[Treatments](https:\/\/www.jaxallergy.com\/allergy-treatments\/)\n\n[About Us](https:\/\/www.jaxallergy.com\/allergy-doctors\/)\n\n[About Dr. DeMarco](https:\/\/www.jaxallergy.com\/allergy-doctors\/patrick-demarco\/)\n\n[About Dr. Lupoli](https:\/\/www.jaxallergy.com\/allergy-doctors\/thomas-lupoli\/)\n\n[Office Locations](https:\/\/www.jaxallergy.com\/locations\/)\n\n### Navigation\n[Allergy Shots & Testing](https:\/\/www.jaxallergy.com\/allergy-shots-and-testing\/)\n\n[Patient Forms](https:\/\/www.jaxallergy.com\/forms\/)\n\n[Blog](https:\/\/www.jaxallergy.com\/blog\/)\n\n[Contact](https:\/\/www.jaxallergy.com\/contact\/)\n\n[Make An Appointment](https:\/\/www.jaxallergy.com\/make-an-appointment\/)\n\nCopyright © 2025.

Boilerpipe Text	Shellfish Allergy Symptoms and Diagnosis When a person has a shellfish allergy, they may exhibit the following signs and symptoms within a short period of consuming shellfish: Vomiting and upset stomach or gastrointestinal discomfort Diarrhea Hives (urticaria) all over the body Itching/numbness in and around the mouth or throat Swelling of the tongue and lips Dizziness and confusion Tightening of the throat or feeling of being unable to breath Nonproductive cough Pale skin Anaphylaxis—a life-threatening reaction that can lead to shock, and death in extreme cases. If you or your child have an anaphylactic reaction call 911 or seek emergency medical care immediately. If you suspect you have a shellfish allergy or you’ve had any of the above symptoms after eating shellfish, make an appointment with your allergy specialist as soon as possible. At your appointment a detailed personal history will be taken. This will include foods you normally eat, symptoms you have experienced, how long these symptoms lasted and what, if anything, you did to treat your symptoms. A shellfish allergy diagnosis can sometimes be complicated as symptoms vary widely from person to person, and it is very possible for someone to have different symptoms during each reaction. Additionally, people with shellfish allergies do not necessarily have to eat it to have a reaction. They may react when other foods come in contact with shellfish during the food preparation process. Reactions often affect multiple parts of the body—skin, respiratory tract, gastrointestinal tract, and the cardiovascular system. In most cases your shellfish allergy will be diagnosed by a skin-prick test or a blood test. The skin-prick test will be performed in the allergist office and you can expect to have results fairly quickly—often within 15 minutes. A small spot on your forearm or upper back will be pricked with a sterile tooth pick-like stylet and drop of liquid containing the allergen will be introduced at prick site. If you have a positive reaction to shellfish you will immediately develop a small raised hive where your skin was pricked. For blood tests, a blood sample is taken and tested for the presence of Immunoglobulin E (IgE) antibodies—these antibodies are produced by your body in response to a particular allergen (in this case shellfish) and results are typically available in a week to two weeks.

Although shellfish allergies are not as prevalent in the US as peanut allergies, they can be one of the worst allergies and sends more people to emergency rooms than any other food allergy. As with other food allergies, an allergic reaction to shellfish can range in severity. Reactions can be mild to life-threatening leading to anaphylaxis—it’s advised that individuals with shellfish allergies always carry epinephrine auto-injectors. It should be noted that shellfish allergies are not the same is an allergy to fish. If you are allergic to shellfish you do not necessarily have to avoid fish and fish allergy sufferers may not be allergic to shellfish. Typically a shellfish allergy is lifelong and approximately 60 percent of shellfish allergy sufferers did not have a reaction until they were an adult. The most common causes of shellfish allergy are from shrimp, crab, and lobster. As stated above, finned fish are not in the same biological family as shellfish and allergy to one does not always mean an allergy to the other. There are two kinds of shellfish sufferers must be aware of: crustaceans (shrimp, lobster, crab, etc.) and mollusks (clams, mussels, oysters, and scallops)—reactions to crustaceans tend be the most severe. People tend to tolerate mollusks much better than crustaceans. ## Shellfish Allergy Symptoms and Diagnosis When a person has a shellfish allergy, they may exhibit the following signs and symptoms within a short period of consuming shellfish: - Vomiting and upset stomach or gastrointestinal discomfort - Diarrhea - Hives (urticaria) all over the body - Itching/numbness in and around the mouth or throat - Swelling of the tongue and lips - Dizziness and confusion - Tightening of the throat or feeling of being unable to breath - Nonproductive cough - Pale skin - Anaphylaxis—a life-threatening reaction that can lead to shock, and death in extreme cases. If you or your child have an anaphylactic reaction call 911 or seek emergency medical care immediately. If you suspect you have a shellfish allergy or you’ve had any of the above symptoms after eating shellfish, make an appointment with your allergy specialist as soon as possible. At your appointment a detailed personal history will be taken.

Additionally, anyone with shellfish allergies must check ingredient labels on packaged and prepared foods. You should also avoid seafood restaurants, even if you order non-shellfish containing meals it may be impossible for the kitchen to not cross-contaminate your meal. The federal Food Allergen Labeling and Consumer Protection Act (FALCPA) requires all packaged food products sold in the US that contain shellfish in its ingredients, must list the specific shellfish item on the label. Currently, advisory labels such as “may contain” warnings are not required to be on packages, but some companies list whether a food was produced in a facility or on equipment that comes in contact with shellfish. The absence of shellfish terms does not mean the food is safe for you though. If in doubt, contact the manufacturer and avoid the food unless you are certain it is free of allergens. ## Treatment for Shellfish Allergy Reactions Since food allergies are the most common causes of anaphylaxis, patients with shellfish allergies should always carry epinephrine (adrenaline) auto-injectors with them—this is the only first-line treatment for anaphylaxis. If you are not sure whether an allergic reaction is leading to anaphylactic shock, you should use the epinephrine treatment anyway—the benefits of early use outweigh the risks of an unnecessary dose. ## Additional Steps to Take for Children with Shellfish Allergies Since dangerous reactions can occur at any time, it’s important that parents of children with shellfish allergies make sure family, friends, and caregivers are aware of the child’s allergy. These additional steps are important for children with shellfish and other food allergies: - Involve all caregivers: relatives, babysitters, teachers, and the school nurse need to be made aware of your child’s allergy. Emphasize with them the severity of the allergic response and ensure there are emergency supplies on hand. - Create written plans: list steps that need to be taken if a reaction occurs. Include all medications that need to be given along with dosage amounts, as well as emergency contact information of family members and family physicians and allergists. - Do not allow your child to share foods: children often share their snacks and treats, ensure your child understands the dangers of sharing foods since they may contain allergens. - Purchase a medical alert bracelet: to help adults and caregivers understand your child’s allergies and proper treatments in the case of emergency. This is critical if they are unable to communicate while in the midst of a reaction. The bracelet should include child’s name and specific allergy. ## Allergy Sufferers Should Also Avoid Foods Containing These Ingredients: - Barnacle - Crab - Crawfish (also known as crawdad, crayfish) - Krill and krill oil - Lobster - Prawns - Shrimp (scampi) Be aware that mollusks are not considered major allergens under FALCPA and may not be disclosed on labels. It may be recommended you avoid mollusks and the following items also: - Abalone - Clams - Cockle - Cuttlefish - Limpet - Mussels - Octopus - Oysters - Periwinkle - Sea cucumber - Sea urchin - Scallops - Snails (on menus as escargot) - Squid (also labeled as calamari) - Whelk ## Some Unexpected Sources of shellfish Products: This is not an exhaustive list, but there are some common items that may contain shellfish ingredients. Care should be taken with the following items: - Bouillabaisse - Cuttlefish ink (used as food coloring as well as flavoring) - Glucosamine supplements - Fish stocks - Other seafood flavoring - Surimi (fake crab) If you have a reaction after eating shellfish-containing foods, you should contact your allergy specialist to [schedule a test to determine if you have a shellfish or other allergy](https://www.jaxallergy.com/make-an-appointment/) or if there is some other issue. ### SHELLFISH ALLERGY FAQS # Frequently Asked Questions [What are the common symptoms of a shellfish allergy?]()[Expand]() Common symptoms of a shellfish allergy can include hives, itching, swelling, abdominal pain, nausea, vomiting, diarrhea, difficulty breathing, wheezing, and in severe cases, anaphylaxis. These symptoms typically occur within minutes to two hours after consuming shellfish or coming into contact with shellfish proteins. [Which types of shellfish can cause allergic reactions?]()[Expand]() Various types of shellfish can cause allergic reactions in individuals with shellfish allergies. The most common culprits are crustaceans such as shrimp, lobster, crab, and crayfish. Additionally, mollusks like clams, mussels, oysters, scallops, and squid can also trigger allergic responses. It's important for individuals with shellfish allergies to avoid all forms of shellfish to prevent allergic reactions. [Can you be allergic to some shellfish and not others?]()[Expand]() It is possible to be allergic to certain types of shellfish and not others. Shellfish allergies can be specific to crustaceans (such as shrimp, lobster, crab) or mollusks (such as clams, mussels, oysters). This means that an individual may be allergic to one category of shellfish but not the other. [Can shellfish allergies develop later in life?]()[Expand]() Shellfish allergies can develop later in life, even if a person has previously consumed shellfish without any adverse reactions. While allergies commonly develop in childhood, it is not uncommon for adults to develop allergies to shellfish or other foods. The severity of the allergic reaction does not necessarily correlate with the age of onset. Shellfish allergies can be serious and potentially life-threatening, regardless of when they develop. It is crucial for individuals who suspect they have developed a shellfish allergy to seek medical evaluation and take necessary precautions to avoid exposure to shellfish proteins. [How is shellfish allergy diagnosed?]()[Expand]() A shellfish allergy can be diagnosed through a combination of medical history, physical examination, and allergy testing. An allergist will review a patient's symptoms, potential triggers, and any previous allergic reactions. Allergy testing, including skin prick tests or blood tests, can help identify specific shellfish allergens. If you suspect a shellfish allergy or have experienced allergic reactions after consuming shellfish, it is essential to consult with an allergy specialist for proper evaluation, diagnosis, and personalized management strategies. [Contact Jax Allergy](https://www.jaxallergy.com/contact/) today to schedule an appointment and get the expert care you need. [What is the recommended treatment for a shellfish allergy?]()[Expand]() The recommended treatment for a shellfish allergy involves strict avoidance of shellfish and any foods or products containing shellfish ingredients. In case of accidental exposure or an allergic reaction, immediate administration of an epinephrine auto-injector (such as an [EpiPen](https://www.jaxallergy.com/patient-education/)) is crucial to counteract [severe symptoms and anaphylaxis](https://www.jaxallergy.com/allergy-treatments/anaphylaxis/). It is also important for individuals with shellfish allergies to carry and know how to use their epinephrine auto-injector at all times. Following an allergic reaction, seeking medical attention is essential for further evaluation and management. [Are there any cross-reactivities between different types of shellfish?]()[Expand]() Yes, cross-reactivities can occur between different types of shellfish. Individuals allergic to one type of shellfish, such as shrimp, may also experience allergic reactions to other crustaceans like crab or lobster. Similarly, some individuals with a shellfish allergy may also be sensitive to certain mollusks, although the cross-reactivity is less common. It is important for individuals with shellfish allergies to be cautious and avoid all types of shellfish to prevent potential allergic reactions. [Can shellfish allergies be outgrown over time?]()[Expand]() Shellfish allergies are generally considered lifelong allergies, and it is less common for individuals to outgrow them compared to other food allergies like milk or egg allergies. However, in some cases, children may outgrow shellfish allergies as they get older. It is important for individuals with a shellfish allergy to undergo proper evaluation and testing to determine if they have outgrown the allergy before reintroducing shellfish into their diet. ### REQUEST AN APPOINTMENT # Fill Out The Form or Call Today\! ### NEED OUR SERVICES? # View our allergy shots and testing page for hours and more information.

For blood tests, a blood sample is taken and tested for the presence of Immunoglobulin E (IgE) antibodies—these antibodies are produced by your body in response to a particular allergen (in this case shellfish) and results are typically available in a week to two weeks. ![shellfish allergy management and treatment](data:image/svg+xml;base64,PHN2ZyB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIHdpZHRoPSI0NTAiIGhlaWdodD0iMjk5IiB2aWV3Qm94PSIwIDAgNDUwIDI5OSI+PHJlY3Qgd2lkdGg9IjEwMCUiIGhlaWdodD0iMTAwJSIgc3R5bGU9ImZpbGw6I2NmZDRkYjtmaWxsLW9wYWNpdHk6IDAuMTsiLz48L3N2Zz4=) ## Shellfish Allergy Management The best and only definitive treatment for shellfish allergies is strict avoidance and elimination of any foods containing shellfish from your diet. Additionally, anyone with shellfish allergies must check ingredient labels on packaged and prepared foods. You should also avoid seafood restaurants, even if you order non-shellfish containing meals it may be impossible for the kitchen to not cross-contaminate your meal. The federal Food Allergen Labeling and Consumer Protection Act (FALCPA) requires all packaged food products sold in the US that contain shellfish in its ingredients, must list the specific shellfish item on the label. Currently, advisory labels such as “may contain” warnings are not required to be on packages, but some companies list whether a food was produced in a facility or on equipment that comes in contact with shellfish. The absence of shellfish terms does not mean the food is safe for you though. If in doubt, contact the manufacturer and avoid the food unless you are certain it is free of allergens. ## Treatment for Shellfish Allergy Reactions Since food allergies are the most common causes of anaphylaxis, patients with shellfish allergies should always carry epinephrine (adrenaline) auto-injectors with them—this is the only first-line treatment for anaphylaxis. If you are not sure whether an allergic reaction is leading to anaphylactic shock, you should use the epinephrine treatment anyway—the benefits of early use outweigh the risks of an unnecessary dose. ## Additional Steps to Take for Children with Shellfish Allergies Since dangerous reactions can occur at any time, it’s important that parents of children with shellfish allergies make sure family, friends, and caregivers are aware of the child’s allergy. These additional steps are important for children with shellfish and other food allergies: - Involve all caregivers: relatives, babysitters, teachers, and the school nurse need to be made aware of your child’s allergy. Emphasize with them the severity of the allergic response and ensure there are emergency supplies on hand. - Create written plans: list steps that need to be taken if a reaction occurs. Include all medications that need to be given along with dosage amounts, as well as emergency contact information of family members and family physicians and allergists. - Do not allow your child to share foods: children often share their snacks and treats, ensure your child understands the dangers of sharing foods since they may contain allergens. - Purchase a medical alert bracelet: to help adults and caregivers understand your child’s allergies and proper treatments in the case of emergency. This is critical if they are unable to communicate while in the midst of a reaction. The bracelet should include child’s name and specific allergy. ## Allergy Sufferers Should Also Avoid Foods Containing These Ingredients: - Barnacle - Crab - Crawfish (also known as crawdad, crayfish) - Krill and krill oil - Lobster - Prawns - Shrimp (scampi) Be aware that mollusks are not considered major allergens under FALCPA and may not be disclosed on labels. It may be recommended you avoid mollusks and the following items also: - Abalone - Clams - Cockle - Cuttlefish - Limpet - Mussels - Octopus - Oysters - Periwinkle - Sea cucumber - Sea urchin - Scallops - Snails (on menus as escargot) - Squid (also labeled as calamari) - Whelk ## Some Unexpected Sources of shellfish Products: This is not an exhaustive list, but there are some common items that may contain shellfish ingredients. Care should be taken with the following items: - Bouillabaisse - Cuttlefish ink (used as food coloring as well as flavoring) - Glucosamine supplements - Fish stocks - Other seafood flavoring - Surimi (fake crab) If you have a reaction after eating shellfish-containing foods, you should contact your allergy specialist to [schedule a test to determine if you have a shellfish or other allergy](https://www.jaxallergy.com/make-an-appointment/) or if there is some other issue.
