What fruits and vegetables retain the most toxins?
“Retains” is the operative word. Most times when we think of pesticides, fungicides and herbicides, we think of toxins on the surface of the food and below is a link of the most sprayed fruits
Yet, the other side of the “retain” issue is that if the pesticides were sprayed during the growth then they may be inside the produce where washing can no longer help. The various chemicals used in pesticides, fungicides, and herbicides are many and nasty. This is why eating organic produce is important whenever possible.
