Be sure to take a look at our list of foods highest in pesticides.

15. Mushrooms


Mushrooms take the number fifteen spot on the clean 15 list for 2012. 14 different pesticide residues were detected among tested samples. Cyromazine was the only chemical found on 100% of tested samples, but is primarily of concern to honeybees, as lists it as a slight toxin to honeybees. It is not considered a neurotoxin, carcinogen, hormone disruptor, or a reproductive/developmental toxin.

14. Watermelon


Although watermelon has been found to have 28 different pesticide residues, the frequency of occurrence is small, with each individual type of pesticide only being detected in up to 5% of samples.

13. Grapefruit


Grapefruit samples tested were found to only have 11 different pesticide residues, with most of them occurring in small percentages.

12. Sweet Potatoes


Sweet potatoes are another vegetable with low levels of pesticide residue. Only 8 were found in samples tested, with all but one being found in less than 4%. The main chemical, Dicloran, was found in about 40% of samples tested, and is only a possible carcinogen according to It is used as a fungicide to prevent a disease in sweet potatoes known as Rhizopus soft rot. This can cause a mushy soft rot on the inside of the root vegetable, occurring during packing or shipping.

11. Cantaloupe (Domestic)


Another fruit on the clean 15 list is this tasty melon. Most pesticide residues were detected in a relatively small amount of samples. Unfortunately, imported cantaloupe was found to have pesticide residue in greater frequencies. Good ol’ American melons!
