Human health risk assessment on residues of multiple pesticides in food: European approach

Summary

This paper reviews the European approach to assessing human health risks from simultaneous dietary exposure to multiple pesticide residues in food, as developed by the European Food Safety Authority (EFSA) and related bodies. It likely outlines the conceptual and methodological framework for grouping pesticides by common mechanisms of toxicity and calculating cumulative risk indices. The work contributes to regulatory science by clarifying how cumulative risk assessment differs from single-compound approaches and what data requirements underpin its implementation.

UK applicability

Highly applicable to the UK: prior to Brexit, UK regulatory practice aligned closely with EFSA frameworks, and post-Brexit the Health and Safety Executive (HSE) and Food Standards Agency continue to draw on similar cumulative risk assessment principles. The methodological approaches described remain directly relevant to UK pesticide residue monitoring and Maximum Residue Level (MRL) compliance under retained EU law.

Key measures

Cumulative exposure estimates; hazard quotients; toxicological reference values (e.g. ADI, ARfD); cumulative assessment groups (CAGs); margin of exposure

Outcomes reported

The study assessed human health risks arising from combined exposure to multiple pesticide residues in food, likely evaluating cumulative exposure against toxicological reference values. It examined methodological approaches for cumulative risk assessment adopted within the European regulatory context.
