Non pas vraiment selon le American Cancer Society:
Alors les pesticides sont mauvais? Non pas vraiment non plus dans le cas des États-Unis:At this time, no research exists to demonstrate whether such foods are more effective in reducing cancer risk than are similar foods produced by other farming methods.
Although vegetables and fruits sometimes contain low levels of these chemicals, overwhelming scientific evidence supports the overall health benefits and cancer-protective effects of eating vegetables and fruits. At present there is no evidence that residues of pesticides and herbicides at the low doses found in foods increase the risk of cancer, but fruits and vegetables should be washed thoroughly before eating.
