Kashrus: Stickers on Produce
A lot of produce sold in stores have identification stickers attached. From a health standpoint, the gluey residue is perfectly safe and it is even safe to eat the whole sticker! But this does not answer kashrut questions. There is no way of knowing what the sticker or the ink printed on it or the glue are made of. Do these pose kashrut issues in any way? Should the area of the skin of a fruit or vegetable where the sticker was attached, which contains traces of the adhesive after removal, be discarded?
