2020

Read source ↗ All evidence

Summary

This 2020 systematic review in Foods synthesises comparative evidence on pesticide residue levels across organic and conventional food products. The review appears to confirm that conventional foods consistently exhibit higher detection rates and concentrations of synthetic pesticide residues than organic equivalents, whilst acknowledging that organic products may still contain trace residues from environmental carry-over or approved substances. The findings contribute to the evidence base informing consumer decision-making, food safety standards, and organic certification frameworks.

Regional applicability

The findings are directly applicable to UK food safety policy and organic certification standards under UK and retained EU regulations. The review's comparative data may inform UK food standards authority guidance and consumer communication about pesticide residue risks in organic versus non-organic produce.

Key measures

Detection frequency and concentration of pesticide residues in organic versus conventional food samples; prevalence of synthetic versus permitted substances in organic foods

Outcomes reported

This systematic review synthesised evidence comparing the occurrence, detection rates, and concentration levels of pesticide residues between organic and conventional food products across multiple studies. The review examined both synthetic pesticide residues and permitted substances in organic produce.
