| | meringue powder eliciting allergic response?
Trying to figure out why our 2 yr old has bad hives for several days. There are many possibilities I am told - viral infection (definitely going around the daycare), reaction to antibiotics (finished his 2 days before the hives), reaction to vaccines (vaccinations including flu vaccine about 2 weeks before the hives), or he was exposed to a new allergen in something he ate.
For the "something he ate" all I can think of that would be new to his diet is the meringue powder I used to ice his birthday cake that he ate the day he got hives the first time, and then I used more meringue powder in pancakes the second day (because we were out of eggs) and then ate more birthday cake the 3rd day.
He has been fine with eggs in the past (he is crazy for fried eggs, just the egg whites) and has french toast for breakfast every morning.
Could meringue powder, as a very processed version of eggs, be particularly more allergenic than normal eggs?
Curious if anyone has seen anything in the literature about this.
