Pesticide residues found on pearl oyster mushrooms

100% 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 pearl oyster mushrooms?

The most frequently detected residues across all 1 samples. This is the complete available table for this monitoring entry.

1samples 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.

EFSA consolidates official control results reported by national authorities; sampling strategies and food coverage differ between countries. It is not a test of every pearl oyster mushrooms product sold in Czechia. This entry’s latest included calendar year release is from 2024.

Published MRLs or tolerances are regulatory limits associated with pesticide use. Consumer-risk assessment is a separate process.

Limited sample coverage. Fewer than 20 samples: useful as a monitoring snapshot, but sensitive to individual results.

Common questions

How to read these pearl oyster mushrooms results

Were pesticide residues detected on pearl oyster mushrooms?

100% of 1 standard-grown samples in the 2024 EFSA consolidated official controls dataset had at least one quantified residue.

Does that mean pearl oyster mushrooms were unsafe?

No. A laboratory detection is not, by itself, a consumer-risk finding. Regulators assess dietary risk separately.

Should I buy organic pearl oyster mushrooms?

There were only 0 organic samples, so Residue Lens withholds the comparison.
