- Bell Peppers
- Imported Grapes
What I noticed is that most of these items contain a large amount of water, which is probably why they are on the list. If the farm is sprayed with an insecticide it will get into the soil and the water supplying that crop, the crop will use the water and voila - insecticide laden produce.
The USDA itself has stated that certified organic produce has required tolerance levels much lower than standard produce (check out their statement here).
So, what it comes down to is this...do you believe that the "pesticides are safe" as has been stated or will you hedge your bets in the 100% Certified Organic corner to keep your family pesticide free (for the most part).
