Pesticide residues found on oranges
95.5% 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.

Residue detail
What was found on oranges?
The most frequently detected residues across all 44 samples. This is the complete available table for this monitoring entry.
44samples 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.
The UK programme is risk-based and targets foods where residues may be expected. It is not a test of every oranges product sold in United Kingdom. This entry’s latest included annual release is from 2023.
Published MRLs or tolerances are regulatory limits associated with pesticide use. Consumer-risk assessment is a separate process.
Moderate sample coverage. 20–49 samples: a useful monitoring snapshot, though not a population estimate.

How to read these oranges results
Were pesticide residues detected on oranges?
95.5% of 44 standard-grown samples in the 2023 UK Pesticide Residues in Food monitoring dataset had at least one quantified residue.
Does that mean oranges were unsafe?
No. A laboratory detection is not, by itself, a consumer-risk finding. Regulators assess dietary risk separately.
Should I buy organic oranges?
There were only 0 organic samples, so Residue Lens withholds the comparison.
