Cheese with a skin would be mould ripened, things like brie are just a white mould. You wont find un-pasturised cheese in the supermarket only speciality cheese shops would have it so you wont ever buy it by accident IYKWIM. I actualy dont see the risk with pasturised cheese as any different to most cold food, in that you cant be 100% sure of the cool chain with supply - so the same goes for yoghurt/dips ect.
I make my own soft cheeses normaly and have stopped while preg, as i have eating deli meat ect, but i have been known to have salad with a sprinkle of feta. We all have to take our own informed choices, its the conflicting info thats a pain in the bum.
