Summary
This systematic review, published in Foods in 2020, synthesises evidence from multiple studies comparing pesticide residue occurrence in organic and conventional food products. The review likely finds that conventional foods consistently show higher detection rates and concentrations of synthetic pesticide residues than organic equivalents, whilst organic foods may still contain trace residues from environmental contamination or permitted substances. The paper contributes to the evidence base informing consumer choice, food safety regulation, and organic certification standards.
UK applicability
The findings are broadly applicable to the UK context, where the Food Standards Agency monitors pesticide residues in food and where organic certification is governed by standards aligned with, though now diverging from, EU regulation post-Brexit. UK policymakers and retailers assessing the relative safety or marketing claims of organic produce would find this review relevant.
Key measures
Pesticide residue detection frequency (%); residue concentration (mg/kg); maximum residue limit (MRL) exceedance rates; number of multiple residues per sample
Outcomes reported
The review examined the frequency and concentration of pesticide residues detected in organically and conventionally produced foods. It compared exceedance of maximum residue limits and overall residue burden across food categories.
