RebYidd23: Many reasons
1) Those non-allergic kids can have allergic siblings.
2) The school building may be used as a disaster relief zone in an emergency, and allergic may be directed to take refuge in said school building during a cs”v emergency precisely because it’s a somewhat controlled safe zone for peanut sensitive children.
3) A kid becomes allergic later on.
4) Next year there may be an allergic kid.
5) Why not? What is the alternative? Schools must be prepared for emergencies and constantly update the supplies on hand – and up their insurance to cover the costs of an allergy emergency? Put lives at risk? Why not just eat other foods?
6) Even kids/people who aren’t deathly allergic to peanuts may still have unpleasant reactions to aflatoxins – and now they have a reason to find a healthier alternative for them.
