Marketing Analyst: We need to offer a peanut butter and jelly sandwich product on the market.
Compliance Analyst: We can't sell peanut butter in these markets, we need to use tahini instead.
Automation Engineer: Ok, we were able to make the robot work with mayonnaise and honey, all the other ingredients aren't working. Can we sell a mayonnaise and honey sandwich?
That counted for allergies other than peanuts too which can be just as severe.
Sensitivity to sunlight is way more manageable (by applying sunscreen and covering the skin) and although kids share food and/or eat them in the same environment I don't think they're carrying UV lights to apply to other kids.
edit: Note that an allergy to sunlight exposure (which is a thing) is not simply treated with sun cream
Can they trigger reaction by simply having it in the room? I can get an allergic reaction from having peanuts in the same room as I'm in, in the same way as a reaction from pollen or from animals. So wonder if other food based allergy can have the same effect on others
