So sorry lizzie. Let us know how you do.
Well, since you were all so helpful with my peanut question I thought I'd sort out cheese once and for all. According to the Food Standards Agency:
"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."
But you can eat: "Many types of cheese including:
Hard cheese, such as Cheddar and Parmesan
Feta
Ricotta
Mascarpone
Cream cheese
Mozzarella
Cottage cheese
Processed cheese, such as cheese spreads"
"Is it OK to eat goats' cheese when I'm pregnant?
There are different types of goats' cheeses available. The type that is probably most common in the UK has a white rind similar to Brie and Camembert. This type of goats' cheese is sometimes called Chevre and is often served in restaurants, for example in a goats' cheese salad. You should avoid this when you are pregnant. However, other types of goats' cheese that don't have this kind of rind should be fine to eat, particularly hard cheeses."
"Can I eat Brie and blue cheese when I'm pregnant if it's cooked?
Pregnant women are advised against eating these types of cheese because of the risk of listeria. However, thorough cooking should kill any listeria, so it should be safe to eat food containing, these and other cheeses such as Camembert or chevre (a type of goats' cheese), that have a similar rind, provided it has been properly cooked and is piping hot all the way through."
On the prawn front they say:
"Avoid raw shellfish when you're pregnant. This is because raw shellfish can sometimes contain harmful bacteria and viruses that could cause food poisoning. And food poisoning can be particularly unpleasant when you're pregnant."
But under things you CAN eat they then say: "Shellfish, including prawns - as long as they are part of a hot meal and have been properly cooked"
So annoyingly cold prawns are not covered by the list of can or can't eat! Sorry.
