Many people are also allergic to bleach, gasoline, turtle wax, herbicides, plastic wrap, or boiling coffee. These substances are lethal to them.
Despite that lethality, the time tested approach of not eating the allergen in question has been and is remarkably successful at keeping deaths to a minimum.
What exactly is it about peanut butter that's different to demand a ban?
Read lables...
Peanut products (the nuts, oil, butter) are in an amazing number of products...from cake mixes, to cookies, processed snacks to even hot dogs.
When we have kids with peanut allergies, we don't feed them ANYTHING processed....no bakery products, cookies, prepacked products etc. They allergy is so severe that if they eat a cookie that came from the same factory that makes peanut butter cookies, they can go into anaphylactic shock.
So they get plain meats, veges, fruits etc. And the nursing staff still watches closely. Seriously, next to shellfish, this is the worst allergy I've ever seen.
How many kids bring bleach, gasoline, turtle wax, or herbicides to school?
While I don't understand peanut allergies, I haven't heard of any allergies to plastic wrap.
In schools, banning peanuts is a mere inconvenience, its not life altering, or somehow going to change the kids life.
Unless the kids is allegic to peanuts, in which case, not banning it, can kill them.
