Are the pesticides in my food dangerous?

This question has attracted a lot of attention from parents, government officials, and the scientific community. The prenatal and early childhood periods are thought to be the times when the developing nervous system in humans is most vulnerable to damage by a wide variety of chemicals, including pesticides. Several recent studies have shown that children whose mothers had higher levels of pesticides in their blood or urine during pregnancy were more likely to have lower scores on IQ, memory, and reasoning tests (Bouchard et al 2011; Engel et al 2011; Rauh et al 2011). Another study looked for a potential relationship between attention-deficit/hyperactivity disorder (ADHD) and pesticides in children and adolescents between 8 and 15 years of age. This study found that the children and adolescents with higher levels of pesticides in their urine had greater odds of having ADHD. However, none of these studies were able to ascertain where the pregnant women or children/adolescents were exposed to pesticides. We are exposed to pesticides on a regular basis through a variety of sources, including foods and the home environment. The American Academy of Pediatrics (AAP) concluded in a 2012 report that organic produce contains lower levels of pesticides and that consuming organic produce reduces a child's exposure to pesticides, but that the health impact of such a reduction is unclear.
