The Organic Center has just released a free pocket guide, which lists fruits and vegetables that pose the greatest risks from pesticides. All conventional produce is grown with pesticides and chemical fertilizers. But some are more heavily sprayed with pesticides than others. Pesticides can cause developmental problems in children and other long term health effects on adults. It's important to eat organic when possible. If you must purchase conventional produce be aware that the following fruits and vegetables are laden with pesticides and should be avoided or simply opt for other produce not on the list of highly toxic fruits and vegetables.
