The stickers are usually either made entirely of plastic or coated in plastic so are not edible or compostable. I don’t think the glue is edible either. Eating one won’t hurt you, but it’s possible eating glue residue over a lifetime might.

I can’t find sources for that…as far as I can tell labels are food grade/GRAS/similar, but not necessarily digestible per se, and not necessarily compostable. Happy to be proven wrong though:

Not entirely sure what “edible” means tbh.
