This video segment adapted from Playing with Poison describes how children in the Yaqui Valley, one of the largest farming areas in Mexico, have been harmed by chronic exposure to pesticides. To study the long-term health effects of agricultural pesticides, anthropologist Elizabeth Guillette tested children in the Yaqui Valley.
