Detection over time
Samples with at least one validated detection.
5 tested years between 2006 and 2020. Gaps mean no validated tests in this release.

How many were detected?
Number of distinct analytes per tested sample.
Labels show analytes; counts show samples. Metabolites and isomers remain separate. This is not a count of pesticide products applied.
Where samples came from
Origin recorded by USDA.
Origin describes the sampled food. These shares do not compare countries’ residue levels.
All tested analytes
Zero detections here means tested with no validated detection. It does not describe analytes that were never tested.
