All about Shrimp Allergy

Shrimp allergy is a kind of seafood allergy, triggered by the proteins present in the shrimp. Our immune system mistakenly identifies the proteins as harmful and reacts against it. This can give rise to reactions such as swelling and itchiness of tongue/mouth, nausea, and diarrhea etc. People with shrimp allergy can be allergic to other seafood such as crab, crayfish, oysters, shrimp, mussels, clams and abalone.

Shrimp Allergy Symptoms:
