Samb0, there is a lot to be said for buying organic.

Strange that it is cheaper to buy 'food' that has undergone the various treatments than it is to buy food that has simply grown in the natural way! Surely that says that the treated food is not as good. Otherwise why are we not paying to have all the treatments done?

With the prices in the supermarkets going up and up they catch up with the price of organic produce now so the local farmers markets look like the way to go. It would be nice to know that all irradiated foods have to be labeled such so the consumer can make a choice !

Food Irradiation... you've got to be kidding!!!
I work at the produce markets in the wee hours of the morning and know the quality of produce, the ONLY reason for food irradiation is to keep food longer than it should be.
Irradiation kills the natural bacteria and bugs so the food looks better WAY past its use by time. DONT TOUCH IT !!!!
Here is a pic of from my local "Fresh food people" and still on the shelf.

I have also seen mould on the stems of spinich and silverbeet in the same supermarket.
"Farmers markets" might be doubtful also if they are the growers thats fine... but often buyers come to the produce market on Friday morning and buy up the old unsold stock keep it for a few days out of a coolroom and sell it Sundays at the Farmers Markets.

The only way to know if the stock is fresh is buy it with the stalks and or outer leaves on.
