Yes, they still do - though I'll touch on liability in just a second - so long as they're not lying and claiming it's the law.
As for safety and liability - liability from what? I know, I know - the "OMGSHARPOBJECTS!" bit. Aside from the fact that I could just as easily cut my hand on something sharp, or get sick from touching something with my hands and then picking my nose (or the other way around), the thing is that I don't see how posting a "barefoot at your own risk" sign wouldn't cover that one up nicely - especially as most people don't walk on sharp things with or without shoes on. And those who can't see/feel if they're about to step on something sharp generally don't, I'm certain, go barefoot.
But really, nobody tries to defend these rules by saying it's a liability issue. They always just claim its somehow unhygenic, as though having barefeet suddenly means you're walking around with the plague or something.
