Hey MissM

I think FETA is off the menu?? Any mouldy cheeses are a no no. Im pretty sure Jarlsberg is ok & I think Swiss is too. Just cheeses like Brie & Camembert are a definate NO.
Do you mean the tinned tuna? Tinned Salmon & Tuna are ok.

Im sure there would be some more info on BB here as well outside of the forums if you have a search. HTH Cheers
