Back when I first ate sushi, my mom always ordered spider rolls. I’d eat them, get an itchy mouth, but assume it was the Wasabi. Then I got braver and ordered other stuff and even with Wasabi, itch gone.

I already knew I was allergic to shrimp and lobster, but crab had always been fine. Spider crabs and blue crabs are in fact not fine for me. Other shellfish is interesting:

Can I eat…
Clams? No.
Oysters? Yes.
Mussels? Yes.
Scallops? Yes.
Conch? Yes.
Crabs? Maybe.
Lobster? No.
Fish? Yes.
Shrimp? No.

So I have a shellfish allergy that doesn’t always trigger. It always triggers with what it does trigger though.
