USDA's 2015 pesticide report is promising
Samples are tested for pesticides and commodities, and randomly taken to be close to the time and point of consumption without regard to country of origin variety, growing season or organic labeling.
“In 2015, over 99 percent of the samples tested had residues well below the tolerances established by EPA with 15 percent having no detectable pesticide residue,” the USDA reports.
After testing all samples, only less than one percent were shown to exceed safe levels and only 2/3 of those were originally grown in the U.S.
