Generally speaking they will be pasturised in Australia, due to our food safety laws.
Only eat them cooked though, just to be sure, as the storage, transpor and maufacturing process can be iffy...even if it is pre-packaged.
I would just steer clear of anything if you dont HAVE to eat it.
Hi All

My doctor referred me to the Food Authority website - here is the link Pregnancy and food safety | NSW Food Authority: safer food, clearer choices

It has pretty much everything you need to know about what you can and cant eat.

Hope that helps!
