the thing you need to be concerned about when it comes to dairy products, is the pasturisation.
There isnt a milk product sold in Australia that isnt pasturised, excluding some soft cheeses.
So brie , camambert, blue vein all NO!! lol
The process of the pasturisation kills the bacteria, however as I said, anything not pasturised is your concern. so no delli cheeses, farm cheeses, or soft/semi-soft cheeses.

HTH
