The Environmental Working Group (EWG) states that "commercial baby food is the dominant source of unsafe levels of pesticides in food". Many foods tested, including non-organic baby foods, contain levels of pesticides that are considered unsafe for infants and young children. Certain produce items are known to have higher levels of pesticides than others. Apples, grapes and peaches are among the produce items that contain the highest amount of pesticides. EWG reports that "about one apple in eight will expose a child to an unsafe dose".
The good news is that feeding infants organic baby food can significantly reduce pesticide levels in their bodies. Chensheng Lu, assistant professor of environmental and occupational health at the Rollins School of Public Health led a study on pesticide levels in young children. Chensheng Lu measured the pesticide levels in children who ate non organic foods. He then switched the children to a 100 percent organic diet. After five days of the children eating organic foods, urine tests showed that the pesticide levels in the children's bodies dramatically dropped. Urine samples did not detect any organophosphates in the children's bodies. Organophosphates are a particularly dangerous neurotoxin pesticide that has been proven to harm the nervous system of children.
