I can't speak to British laws, but in the USA all raw milk cheeses must be aged at least 60 days. That is currently being reviewed and may be amended to 90 days. In theory, the starter bacteria eat up all of the "food" within 60 days, so there is nothing for pathogenic organisms to live on. We are required to label our cheeses as "raw milk" or "unpasteurized" just so the consumer knows what they are getting. It is not really a warning. Even so, some retailers refuse to carry raw milk cheeses.
So in the USA, it is illegal to sell fresh cheeses like Brie or Mozzarella made with unpasteurized milk. Europeans do it all the time.
