Hi
I'm not medically qualified either but I've read in several books on nutrition and pregnancy that hard cheeses are OK, it's soft cheese that needs to be pasteurised and it's best to avoid pasteurised soft cheese too. And no mould-ripened cheeses with an edible rind eg brie, camembert, pont l'eveque. Also you should avoid slightly more solid cheeses that don't grate easily and that are often coated with wax to preserve them - eg habarti, muenster, port salut, taleggio. blue cheese is a total no-no.
But my book says
" the UK department of health says that the following cheeses are safe to eat: cheddar, parmesan, cornish yarg, red leicester; softer cheeses that do not have any mould or rind and are made from pasteurised milk eg cottage cheese, ricotta and mozzarella; processed cheese and cheese spreads" (yuck).
I'm a cheese lover too, and I'm being careful but not obsessive. I'm currently craving cheese on toast and it makes the packet versions of good cheeses slightly more bearable when they're going a nice brown at the edges and covered in worcester sauce!!!
