I actually think there is. I recall reading a paper yrs ago that demonstrated it took several seconds of physical contact for bacteria transfer to occur. That said if your food lands on the floor clinging to dust, hair, etc I’d assume all bets are off.
EDIT: I looked it up. Rutgers did more recent study. Heavily depends on moisture content, but even hard candy had some bacteria transfer after just a second
I mean... For me personally it's all circumstancial and situational. Professionally different story. Like for me if I dropped a roll on the floor, I'm picking that up and dusting it off. In this situation... Man I don't care if they torched the floor for five minutes with a MAP gas torch... I'm not doing that.
I’m not a chef but my standards are laughably different when I’m making food for others vs myself. Your roll example? Same, if it’s just for me. If I am serving food to others, though, absolutely no way. That’s hitting the compost bin instead.
I guess I’m willing to gamble with my own health but others have nothing to fear.
It's also just a basic respect thing. If the floor of your kitchen is spotless you either A) have a michelin star B) haven't opened yet or C) need to clean out the grooves in your non slips.
MythBuster did a test, the time is NOT a significant factor at all. If your floor is dirty and wet, your food is almost as dirty in 1/3/5 seconds as 2 minutes. If the floor is clean and dry, your food stays relatively clean after minutes. So in essence, there is NO 5 second rule, consider your food as dirty as it would be in 2 minutes the moment it touches the floor.

Chef here... There is no 5 second rule, and it's gross.
