Pesticide residues found on radishes
43.3% of standard-grown samples had at least one detected residue. Standard-grown means samples not identified as organic (called conventional in the source data). Detection does not, by itself, mean the food was unsafe.
All reported results below quantification

Annual context
How monitored results changed
Each row is a separate targeted survey. Samples can differ by retailer, origin and season, so this is context rather than a trend claim.

What was found on radishes?
The most frequently detected residues across all 689 samples. This is the complete available table for this monitoring entry.
689samples checked
Detection does not establish harm. Health risk depends on both toxicity and the amount a person is exposed to.
What do these types mean?
- FungicideControls fungal diseases such as moulds and mildews.
- InsecticideControls insects that damage crops or stored food.
- HerbicideControls weeds competing with a crop.
- Growth regulatorChanges plant growth, development or ripening.
- Other / mixedCovers multiple substances or a role that cannot be reliably assigned from the published name.
These labels describe agricultural function, not a toxicity ranking.

“Higher result” is an approximate 95th-percentile observed concentration, not a safety threshold. Amounts of different pesticides should not be added together or compared directly. Functional types describe their usual agricultural role; they are not hazard or toxicity rankings.
ADI and ARfD are intake reference values, not limits for one food sample. A personal assessment would also require consumption, body-weight and wider exposure data. Source programmes report legal Maximum Residue Level results separately.
What this tells you
A monitoring result, not a verdict.
USDA PDP selects rotating commodities, with emphasis on foods important to consumer diets, including foods eaten by infants and children. It is not a test of every radishes product sold in United States. This entry’s latest included calendar year release is from 2020.
Comparable annual records are available for 2020, 2019.
Published MRLs or tolerances are regulatory limits associated with pesticide use. Consumer-risk assessment is a separate process.
Broader sample coverage. At least 50 samples: broader monitoring coverage, but still targeted rather than random.

How to read these radishes results
Were pesticide residues detected on radishes?
43.3% of 651 standard-grown samples in the 2020 USDA Pesticide Data Program dataset had at least one quantified residue.
Does that mean radishes were unsafe?
No. A laboratory detection is not, by itself, a consumer-risk finding. Regulators assess dietary risk separately.
Should I buy organic radishes?
The monitored organic samples had a 5.3% detection rate, compared with 43.3% for standard-grown samples. This is a shopping-priority comparison, not a health-risk score.
