1. It's not a disability.
2. Even if was to be defined as one, the schools also have to take safety into the equation. When and if they have to make the call, the only safe solution is isolation during meals. As somebody already posted, contamination is possible because the safeguards do not exist at home.
Regarding #1, it is a common opinion that a
severe peanut allergy is considered a disability under the ADA as it can limit the major life activity of breathing and/or eating. The 9th Circuit court noted in Fraser v. Goodale in 2003 that "Like our sister circuits, we hold that, broadly speaking,
eating is a major life activity. However, eating specific types
of foods, or eating specific amounts of food, might or might
not be a major life activity. If a person is impaired only from
eating chocolate cake, he is not limited in a major life activity
because eating chocolate cake is not a major life activity. On
the other hand, peanut allergies might present a unique situation
because so many seemingly innocent foods contain trace
amounts of peanuts that could cause severely adverse reactions."
I can see why schools and other areas of public accommodation are treating peanut allergies seriously.
