Eric Bjerregaard, Those studies are relevant to the topic at hand, which is GMO farming and its effect on the environment and public health.  You don't live in Hawaii, but everyone in Hawaii who is familiar with this issue knows that the GMO corporations in Hawaii use chlorpyrifos in large quantities.  Prenatal exposure to chlorpyrifos was determined in one study through umbilical cord blood plasma.  Both studies were published in peer reviewed journals.  Both studies show that chlorpyrifos is associated with neurodevelopmental problems.  So much for your claim of an "impeccable safety record."
