Even though they both fall into the category of seafood, they are biologically different. Unless a person has a fish allergy, fish will not cause an allergic reaction in someone with a shellfish allergy. Shrimp, crab, or oysters are crustaceans, while clams and mussels are mollusks.
The Food Allergy and Anaphylaxis Network (FAAN) is a nonprofit organization that works to educate the public about food allergies and food-allergic reactions. The FAAN website has more information about seafood allergies.

Can you be allergic to only one type of seafood?
30 to 50 per cent of those with an allergy to one of the seafood groups will react to more than one type of fish or shellfish. However, you can also be allergic to just one type of fish or shellfish. Some people have no symptoms, while others may have a mild reaction, such as a runny nose, sneezing, or watery eyes.
Others may experience more severe reactions, including hives, difficulty breathing, and swelling in the face, lips, tongue, throat, hands, arms, legs, feet and/or hands and feet. Food allergy symptoms can range from mild to severe, so it’s important to seek medical attention if you experience any of these symptoms.
Can you be allergic to some seafood and not others?
Some people who are allergic to one type of fish may be allergic to another type of fish or they may have allergies to several crustaceans, such as prawn, crab and lobster. This is called cross-re activity. It is difficult to predict which fish you will have an allergic reaction to, so speak to your clinical immunology/allergy specialist.
Can you be allergic to crab and not fish?
A shellfish allergy is different from an allergy to fish. If you are allergic to shellfish, you can eat fish as part of a healthy diet. The symptoms may include hives, swelling of the face, lips, tongue, or throat, wheezing, runny nose, difficulty breathing, nausea, vomiting, diarrhea, dizziness, headache, muscle aches and pains, skin rash, itching, redness and swelling in the mouth, throat and/or eyes.
In some cases, anaphylactic shock may occur, which is a life-threatening condition in which the body’s immune system attacks its own tissues and organs. Symptoms may last from a few minutes to several hours. If you experience any of these symptoms, stop eating the food immediately and seek immediate medical attention.
Why am I suddenly allergic to seafood?
It can be caused by foods that you’ve eaten before with no issues. The exact cause of an allergic reaction to a particular food is not known.
a family history of allergies, such as a parent or sibling who has had allergies to food or other substances, as well as other family members who have had similar reactions to similar foods; exposure to certain allergens (such as pollen or dust mites) in your home or workplace; and the presence of certain substances in food that may trigger a reaction. Some foods are more likely to trigger allergies than others.
For example, eggs, peanuts, tree nuts, wheat, soy, milk, fish and dairy products are among the foods most commonly associated with allergy-related reactions. Other foods may also trigger allergic reactions, depending on the type of food and how it’s prepared.
Can I eat imitation crab if I’m allergic to shellfish?
Can someone eat imitation crab if allergic to shellfish? Likely not. This is due to the fact that imitation crab typically contains 2% or less of king crab meat and also contains natural and artificial extracts of the crab’s shell.
A crab is a crustacean that lives in the ocean. A lobster, on the other hand, is an omnivore, meaning that it eats a wide variety of different types of food, including fish, crabs, clams, mussels, oysters, and shrimp.
Are shrimp and lobster allergies the same?
People with one shellfish allergy are more likely to have an allergy to other species. If you are allergic to crab, you may also be allergic to lobster, shrimp and other crustaceans.
If you are allergic to clams, you may also be allergic to other mollusks, such as mussels and oysters. If you have one or more of these allergies, it is important to talk to your doctor about the best way to manage your allergies.
How do you test for seafood allergy?
Someone has a blood test. Also called an allergen-specific IgE antibody test or radioallergosorbent (RAST) test, this test can measure your immune system’s response to shellfish proteins by measuring the amount of certain antibodies, known as immunoglobulin E (IgE), in your blood. The RAST test is a simple blood test that can be done at home or at a doctor’s office.
You’ll need to take the test at least once a month for the first year, and then every three months for up to five years. The test measures the level of antibodies that are produced by your body when you’re exposed to certain allergens, such as peanuts, tree nuts, eggs, fish, or dairy products.
If you have an allergy to one of these foods, you’ll be tested for an antibody to the protein in the food that’s causing your allergy. Your doctor will also test you for other allergies, including asthma, hay fever, eczema, lupus, rheumatoid arthritis, psoriasis, food allergies and food sensitivities.
What are the 4 types of allergic reactions?
Allergic reactions can occur within minutes, hours or even days after exposure. The most common allergic reaction is anaphylaxis, which occurs when the body’s immune system mistakenly attacks the lining of the airways, causing swelling and difficulty breathing. It can be life-threatening if it is not treated quickly. In severe cases, it can lead to death. Other reactions include hives, wheezing, swelling, redness and swelling around the eyes, nose and mouth.
These symptoms can last for days or weeks, and may be accompanied by other symptoms, such as fever, chills, headache, muscle aches, nausea, vomiting and diarrhea. The severity of these symptoms depends on how severe the reaction was and how long it has been going on. Some people may not have any symptoms at all, while others may have a severe reaction that lasts for weeks or months.
How long after eating seafood can you have a reaction?
Symptoms usually start within 30 minutes of eating and include nausea, vomiting, stomachache, dizziness, and headaches. A drop in blood pressure is one of the consequences of a severe episode. Antihistamines may be used to treat mild symptoms. Treatment is symptomatic and supportive. Antihistamines can be used to reduce the severity of symptoms, but they may not be effective in all cases. In severe cases, the patient may need to be admitted to hospital.
Is calamari shellfish or fish?
Shellfish can be categorized into two categories. Not all shellfish are classified as crustaceans. The term “mollusk” is derived from the Greek word μόλος (moleos), which means “shell” or “skin” and is used to refer to a group of animals that have a shell or shell-like structures on their bodies. The word “mussel” comes from μουστήριον (musetrios) meaning “soft shell,” and στραφορία (sarpa) which is the Latin word for mussel.
