I am from Edmonton, Alberta, Canada and probably for the last 10 years 95% of the daycares and schools up here are "nut-free". I have a brother with a bee allergy and am very aware at how quickly anaphylactic shock sets in, so I am very careful at what I send in my kids lunches. Even my kids watch when we are grocery shopping, they will pick up an item off the shelf and ask "Can we take this in our lunches?" and it means "does this contain nuts?" A lot of articles I read from the US are anti-nut free schools, but I do agree that with a little research and understanding maybe people would change their mind when they realize that for some of these kids, even being in the same room as a peanut butter sandwich can give them an allergic reaction.
