New FAO/WHO report highlights food safety risks from chemical contaminants in agrifood water

Amid growing use of alternative water sources in agriculture, experts raised concerns about harmful chemical contaminants entering the food chain. Using a global framework, the group identified high-priority substances – including arsenic, lead, cadmium, fluoride, microcystins, and PFAS (Per- and Polyfluoroalkyl Substances – or “forever chemicals”) – based on dietary exposure risks.

The report highlights gaps in monitoring, regulation, and standardized assessment methods. Participants urged enhanced cross-sector collaboration under a ‘One Health’ approach, alongside improved guidance, research, and capacity building to better manage chemical risks in agrifood water systems.
