(potentially, no) My DH has watched our DD nearly die. Several times-- and most often from a source that we've never adequately identified, in spite of fairly vigorous detective work that would make Perry Mason's team proud.
He just somehow has a disconnect in his brain about this. Some people do. It's not that he doesn't listen to ME (and her) and it's not that he's not careful or is disrespectful-- he's not. He just doesn't live in the same head space with it that I do-- and that DD does, honestly. I've occasionally wondered if it isn't the difference between EG/PG and HG, but I'm probably being unfair.
There is a lot of parallel processing and high-speed risk-benefit analysis that has to go on continuously in the background to manage this successfully. Truly. All food everywhere is a risk, all the time, and anywhere that food has BEEN is almost as risky, as are people who might have food ON them and be capable of transferring that food to you somehow.
For most people, that level of vigilance is simply not realistic or sustainable. It's a very good thing that just watching out for sources in food to be consumed is enough for about 99% of people with food allergies. Living the way that we do is for the birds, to be frank. It's hard.
