CodexMRLs (CXLs) are internationally agreed food standards that are established for pesticide residues in or on food. Information on CXLs is availableon our website. In December 2022, the Codex Alimentarius Commission adopted new CXLs for a range of pesticide active substance/crop combinations. Agreed CXLs are voluntary and implementation by member countries is not automatic, but they may be adopted as GB MRLs provided that they are supported by GB assessments. Following a review by HSE, the CXLs adopted in December 2022, that meet the required level of protection for UK consumers, have now been adopted as GB MRLs. The full list of CXLs adopted as GB MRLs, along with the evaluation report/reasoned opinion and decision document supporting each CXL adopted, isavailable on our website. The new MRLs came into force on 8December 2023 as indicated in theGB MRL Statutory Register. |
