Summary Introduction

To determine: Whether switching to an organic diet lowers the amount of pesticide residues excreted by the children.

Concept introduction: Conventionally, in fruits, vegetables, and grains that are produced, pesticides are used. Pesticides such as malathion and chlorpyrifos are neurotoxicant. At high levels, they work by inhibiting acetylcholinestrase.  This can lead to paralysis, breathing problem, and even death. Due to its toxic effect, the fruits and vegetable are produced through organic farming without use of pesticides and gain the USDA’s organic label.
