I ate what I wanted to eat. the things they tell you to avoid are often unpasturised things and I don't think I've ever come across unpasturised cheese etc in my life!
Liver was another one (too much vitamin A apparently), but I still had the odd liver and bacon casserole. I would imagine only someone who eats such things morning noon and night would be in any high risk.
I think there is some sort of 'no no' about shellfish. I can't remember what it is - is it uncooked shellfish like oysters? Can't say I ever ate them anyway!
If you are uncertain, search for pregnancy websites - it will definitely say on them.
