All products imported into the UK under any trade deal must comply with our import requirements. This includes maximum residue levels (MRLs) on imported food, which set out the maximum allowable concentration of a pesticide residue in or on food imports. The UK’s pesticides regulations set a high level of protection for consumers. They are set after a comprehensive scientific assessment of the properties of the active substance and the intended uses of the pesticide. The UK’s regime includes provision for import tolerances, which are MRLs set to take account of residues on imported produce arising from uses and authorisations in other countries. These are set using the same safety criteria as for domestically produced food. Therefore, import tolerances ensure that imported produce is safe for UK consumers to the same level of safety as MRLs applied domestically. The Health and Safety Executive (HSE) employs a wide range of monitoring and intelligence-led enforcement activities to ensure that the supply and use of pesticides complies with legal requirements. This includes an annual pesticide residue monitoring programme which is representative of the country’s food supply.
