Crab vs. Crabcakes

Years ago after eating crabcakes my husband had a severe allergic reaction and was told not to eat crustaceans. Sometimes I would find out after we had eaten something that it actually contained shrimp, but he never had a reaction to that.

Recently, he went to an allergist who tested him and showed that he was no longer allergic but only tested him using shrimp. However, he's eaten crab on a regular basis and been fine (we live in Vegas so tons of all-you-can-eat crab legs for him). But now he had a crabcake and had another severe reaction.

Is there some unusual ingredient specifically in crabcakes that might cause the reaction? Is the way the crab is prepared for crabcakes different than other preparations? We can't figure out why that is the only thing that causes a reaction while binging on crab has no effect.

A lot of restaurants say they're serving crab but they're really serving a crab substitute, most of which are made from other kinds of fish. I think more research is needed.

Well, it sounds like a "true" allergic reaction. (to this non-doctor)

Processed food can have uncountable ingredients. Has he ever reacted to anything else?

Has the allergist said anything about carrying an Epi-pen? At least have Benedryl and Alevert with you at all times. You can take both. They work differently. Advice from non-doctor, so ask your real doctor!
