I see buffalo has already supplied a link.
I do find it hard to believe that you've been involved in organic food industry and never heard of this.
The only REALLY safe organic food is that in which ZERO pesticides, herbicides, insecticides, botanicals or minerals are used.
And unfortuately, I know of
no large scale organic farms that can operate that way. Their yields would be literally eaten alive before they could even harvest it. Even a small scale organic farmer in certain environments would have trouble growing w/out any of this stuff.
I've been in the fields, on both small scale and larger scale organic farms. As well as a few aquaponic and hydroponic farms (which I am less knowledgeable about but learning)------my newest neighbor is an aquaponic farmer, and I'm about to go tour his facility this month
One of the problems I have noticed with some so-called organic farms is that to be certified, they only have to free of synthetic pesticides/herbicides for THREE years. I always laugh a little, since the soil of these places still has tons of chemicals in it. The other problem is that organic pesticides are not as long lasting and therefore not as effective as the synthetic ones, and often have to be applied heavier and more often.
there is just a lot about organics and organic farming that you really have to know about before you can say it's 100% healthy. I do think it's "better", but it's certainly not in any way totally clean.
However, the beans and potatoes I grow are.
