Now, fear not. According to the USDA’s Pesticide Data Program, more than 99% of foods tested were within the EPA’s safety limits — and more than a quarter had little to no pesticide residue. But still, giving your products a quick wash before eating is an easy habit that pays off in peace of mind (and less surprise crunches in the dirt). In most cases, running fruit and vegetables under water is enough, although this is not always the case.

The concern is valid, as a CNET survey shows that 77% of American shoppers are concerned about rising grocery costs, which makes people want to be more conscious about food waste.
Certain varieties of produce are more likely to contain pesticide residues than others. To help consumers identify which fruits and vegetables are most contaminated, the Environmental Working Group, a nonprofit focused on food safety, published a list known as The Dirty Dozen. The team analyzed 47,510 samples of 46 fruits and vegetables tested by the US Food and Drug Administration and the Department of Agriculture, highlighting those with the highest levels of pesticides at the time of sale.
Strawberries are the product most likely to contain pesticides, according to the study.
What are the no.1 offender pesticides in the latest study of The Dirty Dozen? Strawberries. It may be hard to believe, but popular berries have more examples of chemicals found in them than any other fruit or vegetable included in the analysis.
Below you’ll find the 12 foods most likely to contain pesticides — and the 15 foods least likely to be contaminated.

EWG identified several pesticides during the analysis of the tested samples, and the organization found that four of the five most common pesticides are potentially dangerous fungicides: fludioxonil, pyraclostrobin, boscalid and pyrimethanil.
