I have two reasons to suggest that meat may not be the only trigger for delayed anaphylaxis. Firstly, if there is one known and repeatable example of delayed anaphylaxis, than why not others? It would be hard to prove no other instances exist. Secondly, I now have anecdotal evidence in the form of a comment someone left on this website.Desi French left the following comment:
I became allergic to crustaceans in my early 20s. I have been in full-blown anaphylactic shock; huge hives, not breathing, tunnel, light and all.
Luckily I had just arrived at the ER and they saved me. But I have never once had a reaction sooner than 24 hours after ingesting the shellfish.
All events after the first one were accidental; caused mainly by people lying to me about the content of menu items in restaurants and once by there being shrimp in the Reuben sandwich I ordered. I didn’t think to ask!
I had no idea that my pattern was so rare until I met an ER doc who refused to either believe me or treat me. He did call me the next day to apologize after he had done some research but I had to save my own life in his ER with my epi-pen.
The above example is shocking: an ER doctor refusing to treat a patient due to his own ignorance, but I’m sure it happens every day with an wide array of rare conditions that are not considered possible in the mainstream. Kudos to the doctor to having the humility to call and apologize. And clearly he was able to find sufficient evidence to convince himself that such conditions do exist.
