My entire point isn't that you have to worry about the stainless - though there's no way in hell I'd quaff anything from "Triple F Brewing Company's" offerings...Faecal Frosting Froth just doesn't make say, "I'll have another, brother."
My point is there's a reason we have sanitary fittings. Because they can be sanitized, and other options, cannot truly be, without an incredible degree of difficulty and diligence. Screw interfaces, improper welds, etc. - we're talking unreachable microorganisms, not macro-deposits of poop.
Anyway, like I said above, I'm hugely into raw milk, cheese - and I know how close that off-white deliciousness is drawn to some brown-green undeliciousness. Everything has its process. I was an OR scrub corpsman, yes, French chef longer than the two gents who decided to call me ignorant and overly emotional have likely been alive, played a very small part in daily QC at Goose Island (micro sampling in packaging; dO2 and dCO2). In each world, there were requirements; and this is one, with its requirements.
There is no absolute and it all comes down to risk, and what you're willing to live with. Call me risk averse to any food surface, of any kind, contaminated with oodles of poo goo.
