I don't understand it either. I have a classmate whose daughter died because of a miniscule amount of peanut .Her friend's dad made brownies for their slumber party--even made some with no peanuts. Apparently, he stirred the batters with the same spoon. The girl didn't have her syringe with her.
WOW...just the residue on the spoon did it, huh? I agree with some other posters...I had no idea how deadly this allergy is. And why now is it so prevalent? Or did we just never hear about it before?
In studying the familial history of a family that was disposed to a certain rare genetic disease, we found that causes of death were all attributed to cardiac arrest, not the disease which caused it, until later years when the specifics were identified.
