I don't think anyone, child or adult, should be ingesting chlorpyrifos. That said, Dr. Evslin is extremely irresponsible and evinces a profound lack of understanding of basic Science when he discusses the so-called link between chlorpyrifos and behavioral disorders. This claim, which is making the rounds on the web, hinges largely on a correlation/causation fallacy. For example, one can also find correlations between autism diagnoses and increased use of organic foods, global warming, and the adoption of electric vehicles.
