From the picture, that looks like a restaurant and that on the floor would be thrown in the garbage. But I have worked with a few people that would pick it up and put it back in the pan, not me though!
Actually, for a restaurant floor, it looks pretty clean. And...for the record, there are many of those strips that are laying 'on top' of other strips and have yet to touch the floor. IMHO...THOSE are safe to eat.:thumbup:
Personally, as long as no one has stepped on them, I would pick em all up, wash em off and reheat. HOWEVER, I WOULD NOT serve them to anyone else. They would be my secret stash.0
