Are Crab And Shrimp Allergies The Same
If you have ever experienced an allergic reaction to seafood, chances are you have heard of allergies to crabs and shrimp. Both of these seafood delicacies are popular in the United States, but for some, they can be dangerous. In fact, allergies to shellfish, including crabs and shrimp, are among the most common food allergies in the United States. But are crab and shrimp allergies the same? Let's take a closer look.
Shellfish Allergies
Shellfish allergies are one of the eight most common food allergies in the United States. According to the Food Allergy Research & Education (FARE), shellfish allergies affect approximately 7 million Americans. There are two types of shellfish: crustaceans and mollusks. Crustaceans include shrimp, crab, lobster, and crayfish. Mollusks include oysters, clams, mussels, and scallops.
Symptoms of Shellfish Allergies
The symptoms of shellfish allergies can range from mild to severe. Symptoms can occur within minutes or up to two hours after eating shellfish. Common symptoms of shellfish allergies include:
- Hives
- Itching
- Eczema
- Trouble breathing
- Swelling of the lips, tongue, or throat
- Chest pain
- Low blood pressure
- Dizziness or fainting
Are Crab and Shrimp Allergies the Same?
While both crabs and shrimp are classified as crustaceans and can cause an allergic reaction in those with shellfish allergies, the two allergies are not the same. In fact, a person may be allergic to one but not the other. For example, someone with a shrimp allergy may be able to eat crab without experiencing an allergic reaction. However, it's important to note that cross-reactivity between different types of shellfish is common. That means if you are allergic to one type of shellfish, you have a higher chance of being allergic to other types as well.
Diagnosis and Treatment
If you suspect you may have a crab or shrimp allergy, it's important to consult with an allergist or immunologist. Diagnosis typically involves a skin prick test or blood test. Treatment options for seafood allergies include antihistamines to manage symptoms and epinephrine in case of a severe allergic reaction, also known as anaphylaxis.
Prevention
The best way to prevent a crab or shrimp allergy, or any shellfish allergy, is to avoid eating those foods. Always check ingredient labels and ask about the presence of shellfish when dining out. It's also important to carry an epinephrine auto-injector if you have been diagnosed with a shellfish allergy.
Conclusion
In summary, while both crab and shrimp are crustaceans and can cause an allergic reaction in those with shellfish allergies, the two allergies are not the same. It's important to consult with an allergist or immunologist for proper diagnosis and treatment. Prevention of crab and shrimp allergies, and shellfish allergies in general, involves avoiding the foods and carrying an epinephrine auto-injector.
