I realize that this is off topic, but pretty sure that the difference between organic and non-organic in the US isn't whether pesticides were used or not. They can both use pesticides, just different classes of pesticides.
For example, here is a pesticide that has been used extensively by organic farmers:
In 2000, injecting rotenone into rats was reported to cause the development of symptoms similar to those of Parkinson's disease (PD). Rotenone was continuously applied over a period of five weeks, mixed with DMSO and PEG to enhance tissue penetration, and injected into the jugular vein. The study does not directly suggest rotenone exposure is responsible for PD in humans, but is consistent with the belief that chronic exposure to environmental toxins increases the likelihood of the disease.
In addition, studies with primary cultures of rat neurons and microglia have shown low doses of rotenone (below 10 nM) induce oxidative damage and death of dopaminergic neurons, and it is these neurons in the substantia nigra that die in Parkinson's disease. Another study has also described toxic action of rotenone at low concentrations (5 nM) in dopaminergic neurons from acute rat brain slices. This toxicity was exacerbated by an additional cell stressor - elevated intracellular calcium concentration - adding support to the 'multiple hit hypothesis' of dopaminergic neuron death.
In 2010, a study was published detailing the progression of Parkinson's-like symptoms in mice following chronic intragastric ingestion of low doses of rotenone. The concentrations in the central nervous system were below detectable limits, yet still induced PD pathology
In 2011, a US National Institutes of Health study showed a link between rotenone use and Parkinson's disease in farm workers.
Working on a farm can be hazardous to the health of the workers from chemicals, whether organic or not.
There are a lot of natural things that are harmful to humans. I remember Nutrasweet having a commercial where they said it wasn't natural, but couldn't be made without natural things. I immediately thought that the same thing applied to nuclear waste. And arsenic is natural. I'm sure that many of us (myself included) have some misconceptions about these legal definitions for organic, non-organic, natural, etc.
