Editor's Note: This article tracks the updates on New Zealand's revised MRLs in 2024.
New Zealand has its own standards for agricultural and veterinary chemical residues in food. The Food Notice: Maximum Residue Levels for Agricultural Compounds, issued by the Ministry of Primary Industries (MPI), sets forth these maximum residue levels (MRLs). Furthermore, imported food commodities can comply with either a MRL established in the Notice or a Codex MRL. This article offers an update on the changes to New Zealand's MRLs in 2024. For information on Australia's newly revised MRLs in 2024, please refer to the corresponding ChemLinked article.
On December 5, 2024, Ministry for Primary Industries (MPI) of New Zealand issued Food Notice: Maximum Residue Levels for Agricultural Compounds, replacing the previous version issued in December, 2023. The food notice sets new MRLs for difenacoum, difethialone, and diphacinone, and amends brodifacoum, bromadiolone, dieldrin and aldrin, flocoumafen, and pindone, which comes into force on December 9, 2024.
Major changes are outlined in the table below:
