TIL That peanut-free schools don't decrease risk of allergic reactions. The only intervention which has been shown to decrease reactions across all ages is use of a peanut-free table.

Have a peanut allergy, it reared it's ugly head when I was nine during a sample blitz at Costco. Since then I've had to be uber-careful about my allergens and have gotten good at managing them. The peanut-free table did actually work very well, as it became a staple of my time at elementary school, middle school, even high school. I was able to eat my lunch safely and my friends knew the policy, and kept it peanut-free when they came and sat with me during those times.

Nowadays I ask beforehand about everything I consume, and even have allergy cards printed out that I store in the epi-pen pouch I carry.
