My opinion is that currently the organic label is much like the free range label; you would need to do an awful lot of research to be sure that one is actually getting what one is paying for. The definition and testing system is not robust enough currently. Organic does not necessarily mean no pesticides, just approved pesticides.
I bought a bag of organic chicken feed. It came in a large plasic bag.
