The Pesticide Action Network UK (PAN UK) is the British arm of the international Pesticide Action Network, a coalition campaigning to reduce pesticide use and promote safer alternatives in farming and food production. It works through research, advocacy, and practical projects: documenting pesticide harms to farmworkers, pollinators, and waterways; pressing regulators and supermarkets for stricter standards; and supporting integrated pest management and agroecological approaches. Its publications on pesticide residues in food inform consumer debate, though its findings sometimes clash with regulatory risk assessments that judge residues safe within legal limits. PAN UK exemplifies the civil-society side of food safety governance, holding the pesticide approval system to account and amplifying concerns that official channels may underweight. Farmers’ organisations counter that without effective crop protection, yields and food prices would suffer.
