Where in Aus are you? It sounds like it could be NR of NSW? (for the internationals, we have an organic dairy near Kyogle who also sells milk from selected cows (A2 milk), supposed to be low in undesirable fats?.) This milk (the normal one, anyway) is Jersey milk, & my children will not drink it as it tastes 'different'. To me it tastes like I remember milk.... As yet in Aus, we do not have a lot of processing on raw veges (that I lnow of anyway..) We still get eyes sprouting on potatoes, etc. BUT unfortunately we seem to have a govt going down the GM road - even tho the populace do not trust it. I wonder if the US powerbrokers are using pressure to make us go this way (So no competitor can be GM free, & have a powerful market position) Ah well, conspiracy theory mode off.... regards Doug ------------------------ Yahoo!
