The way I understand it, the porno industry in California is pretty well self-regulated with a lot of mandatory STD tests, I'd be a hell more concerned if working on a shoot in Bulgaria. While using condoms would be the smart thing to do, it might also mean that they'd lose market shares to those who don't bother with it, condoms would also mean no facials (or the whole condom deal would seem rather pointless) and I imagine that would turn off another portion of the customer base.
