Shellfish include marine animals with shells, such as shrimp, crab, oysters and lobster, as well as octopus, squid and scallops.

Reactions range from mild symptoms â such as hives or a stuffy nose â to severe and even life-threatening. If you think you have a shellfish allergy, talk to your doctor.
