does it apply to normal karicare or just the de lact ...
It only applies to the Karicare Gold + range (not the TM ones but). The normal Karicare range is not included as it doesn't have the repbiotics added.
It has something to do with the prebiotics they have added not being approved for use in Australia-IMO this is a little more then just an argument over classification.
Not sure about the de lact stuff you may need to contact them and find out, it being unavailable may be because of a different reason.
If they have had to recall their range then they shouldn't be sending out any stock from there stores either.
