I went to the ER last month for a shrimp allergy. I ate a piece of raw shrimp and my throat began to swell up and feel funny. It came to the point where I can hardly breathe. I was told I am not allowed to eat shellfish.
However, I love lobster, mussels, shallots fish and crab I have not had any allergic reaction to any of the above (but only to shrimp), but since what happened to me last month, I would get scared but at the same time, I want to eat the lobster pieces. The other day, I had 2 pieces of cooked mussel from a chinese resturant and I have not had a reaction. (I know I'm a bit stubborn =/ )
I don't know what to do or even how to word my question lol...I guess should I or should I not eat lobster, mussels, etc anymore? I know I HAVE to stay away from shrimp.
I see this post is old, but thought my reply may help someone else.
I am allergic to fish, not shellfish. So, if it lives in a shell, I can eat it. I cannot eat tuna, snapper, cod, anchovy, etc.
The strange thing is, I CAN eat Calamari, which does NOT live in a shell. This breaks the rule.
So, if you have been told you are allergic to one specific type of fish or shellfish as the previous poster, I would taste very tiny bites of whatever you are curious about. Be sure you are home, have some Benedryl or the Epi Pen nearby and good luck!
There are several groups of seafood. If you are allergic to one food in a group, you're likely to be allergic to the others, but maybe not items in another group.
1) Fish: Tuna, mackerel, anchovies, salmon, pike, whitefish, anything with bones on the inside and scales on the outside
2) Shrimp, lobster, crab. Animals with hard skeleton on the outside and lots of legs, sort of insect-like (tasty, though).
3) Squid and octopus
4) mussels, clams, oysters. A soft creature in a shell. Some put scallops in this category, some put them separately, in a fifth group.
Shrimp vs. mussels/lobster
