there is a lot of information out there and a lot of is contradictory...You should have a Food safety site in australia.. I also have a number of pamphlets etc if you would like me to send you some. Mostly all dairy in Australia and NZ is pastuerised... I know definately in NZ everything must be...The problem with the theory of our parents and grandparents eating everything back when is that all of the ready to eat meals etc were not available back then - they made their own- todays society makes it entirely too easy to take something prepared earlier and that will not go through a "kill" stage before eating....Sorry in case you couldn't guess i am Food Safty auditor and so deal with all of this on a daily basis...
