You can't have a sterile environment outside of an O.R. , you can only achieve a very clean environment. In fact after I spoke with Kelly Bloom from Southern Soapers I almost decided against making lotions completely with all the bugs that can grow in them. So if the lady you talked to is not even using very clean practice she is putting herself & customers at risk! Ah-soy~ I am not sure when this was put into law, but I think it's been around for awhile.
