Info from the FSA website.
I personally would ask if it's pasteurised (majority of mass produced cheeses are nowadays) and if in doubt, i wouldn't.
Some types of cheese
Avoid cheeses such as Camembert, Brie or chevre (a type of goats' cheese), or others that have a similar rind. You should also avoid soft blue cheeses.
These cheeses are made with mould and they can contain listeria, a type of bacteria that could harm your unborn baby.
