It's available in the page I linked to.
Actually, some allergies are severe enough that contact with skin can trigger them. Less severe allergies could still be triggered by a scratch or a puncture in the skin through which traces of the food could enter the bloodstream directly. (And remember, "traces" are enough that the food packaging can have warnings about them.)
Also, perhaps I didn't make myself clear enough. I agree that prosecution should be limited to the participating individuals, the group to which "they" was referring to.
If they didn't know who threw the sharp object, shouldn't they have surrounded the area and questioned all the audience members? Otherwise, how much deterrent is there against using big concerts to get away with this sort of thing?
Also, I doubt most people who go on-stage start off with "in case anyone wants to throw stuff at me, bear in mind that I'm severely allergic to certain foods." If someone found out about the allergy otherwise, though, what's to stop them from pretending they didn't know?
And even if they genuinely didn't know about the allergy, would the risk that the food is one those on-stage would be allergic to still be grounds for a Reckless Endangerment charge?
