@Phaedrus- The same sort of regulations against unpasteurized milk are in place here, too. Clabbered milk, which I have found in some health food stores, is not specifically prohibited as long as it's made commercially. Local stores cannot sell unpasteurized milk, or unpasteurized apple cider for that matter.
I like clabbered milk okay, but I think I'll stick to kefir or yogurt for my probiotic needs. There's a kind of cheese that is also prohibited because it uses raw milk, and the process is a little like making clabbered milk. They call it "bathtub cheese", because people sometimes use sanitized bathtubs to hold the milk during the process.
