粮农组织/世卫组织识别号码:	CX-737
文件索引:	CX/PR-RVDF
职责范围:	联合电子工作组（EWG）将： i. 审查食品中兽药残留法典委员会（CCRVDF）和农药残留法典委员会（CCPR）之间已合作完成的工作，确定并在可能的情况下优先排序未来进一步合作的领域，以及如何开展此类合作（例如联合开展、平行开展等），以便利两个委员会对具有双重用途的化合物的审议以及最大残留限量（MRLs）的潜在协调统一。这还可包括对加强 CCPR 与 CCRVDF 之间工作同步性的思考，以及 CCPR/CCRVDF 与农药残留联合专家委员会（JMPR）/食品添加剂联合专家委员会（JECFA）之间协作的探讨； ii. 向 CCRVDF 和 CCPR 提供其初步研究结果的最新情况； iii. 制定一份既作为农药又作为兽药使用的双重用途化合物清单，对于这些化合物尚未建立任何 Codex MRL，或仅建立了一项 MRL；成员国将提供信息以充实该清单； iv. 确定对于类似动物源性可食用商品具有不同 Codex MRL 的双重用途化合物，并逐案建议为相关化合物和受影响商品制定单一、协调一致的 MRL。EWG 可能会建议 CCRVDF/CCPR 考虑选取较高的 MRL 值；以及 v. 审议与 JECFA/JMPR 使用的统一食品描述符相关的事项。

About this webpage

This dedicated page to the CCPR and CCRVDF joint work provides information on the ToR of the Joint EWG as endorsed by CAC48 (2025), circular letters requesting comments on issues about the establishment of single harmonized MRLs for dual-use compounds, including access to the archives of relevant documents providing the historical information for this work, online databases for MRLs for pesticides and veterinary drugs, as well as any other pertinent information applicable to this work and will continue to be updated regularly as necessary.

Rationale for the joint CCPR and CCRVDF work - Dual-use compounds and the need to establish single harmonized MRLs for veterinary and pesticide uses

The effective management of compounds with dual use—as both pesticides and veterinary drugs— by Codex requires close collaboration between the Codex Committee on Pesticide Residues (CCPR) and the Codex Committee on Residues of Veterinary Drugs in Foods (CCRVDF), along with their respective risk assessment bodies: the Joint FAO/WHO Meeting on Pesticide Residues (JMPR) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA).

Currently, separate evaluations by JMPR and JECFA can result in different maximum residue limits (MRLs) for the same compound, depending on whether it is used as a pesticide or a veterinary drug.
This discrepancy creates enforcement challenges for food safety regulators and can negatively affect international trade.

The need for harmonized, single MRLs for dual-use compounds—ensuring both fair trade practices and the same level of human health protection as with separate MRLs reflecting different uses—has been recognized since 2017, notably during the 73rd Session of the Executive Committee (CCEXEC) of the Codex Alimentarius Commission (CAC).

Summary of work initiation and progress

In 2021, CCRVDF, with support from CCPR, highlighted the ongoing lack of harmonization in setting MRLs for dual-use compounds and requested guidance from CCEXEC on mechanisms for cooperation. That same year, CCEXEC recommended the formation of a joint electronic working group (EWG) and the use of virtual technology to advance cross-sectoral collaboration. In response, the Commission established the Joint CCPR/CCRVDF EWG, chaired by the United States and supported by the JECFA, JMPR, and Codex Secretariats. This work will continue as long as both committees find it valuable.

From 2022 to 2025, both CCPR and CCRVDF have strongly supported the Joint EWG, identifying additional cooperative initiatives to facilitate the establishment of harmonized, single MRLs for dual-use compounds, as outlined in the EWG’s terms of reference.

In 2022, CCEXEC and CAC commended the Joint EWG as a cost-effective and practical solution for coordinating work on issues of mutual interest, particularly those concerning dual-use compounds.

As the EWG progressed, it faced challenges, including limited and uneven participation from Codex member countries and relevant animal and plant health agencies, as well as constraints from operating solely on the Codex’s online platform. To address these issues, the Joint EWG recommended convening a virtual EWG meeting, followed by a joint virtual session with CCPR and CCRVDF. This would bring together veterinary and plant protection services from Codex member countries to discuss cross-sectoral issues related to harmonizing MRLs for dual-use compounds—a first-of-its-kind approach in Codex, unanimously supported by both committees. Members and Observers were encouraged to coordinate positions between the CCPR and CCRVDF delegations and to actively participate in the Joint EWG, including by responding to circular letters and by attending the upcoming virtual meetings of the Joint EWG and CCPR/CCRVDF.

Scheduling a joint session of CCPR and CCRVDF

In 2024, the Commission endorsed exploring a virtual session for CCPR and CCRVDF to consider recommendations from the Joint EWG, noting that this would be the first time such an arrangement was made and might be used in the future to address common issues involving different Codex committees.

In 2025, the Commission reaffirmed the Joint EWG’s mandate, endorsed the scheduling of a virtual meeting of the Joint EWG followed by a joint session of CCPR and CCRVDF, and further requested the EWG to prepare a draft agenda for the joint session to be submitted to CAC in 2026 for endorsement. The Joint EWG continues under the leadership of the United States as Chair and Brazil as Co-Chair.

Additionally, a dedicated web page will be created on the Codex website to improve visibility of this joint undertaking and to provide access to working documents and relevant information, facilitating effective participation by Codex Members and Observers.

Ensuring a transparent and inclusive process

The Commission continues monitoring the joint mechanism, as there is no single committee overseeing it. The Codex, CCPR, and CCRVDF Secretariats, along with the chairs of these committees and the Joint EWG, will continue collaborating closely to ensure clear and timely organization and communication. The process aims to be transparent and inclusive, while adhering to Codex procedures despite its novel nature. Ultimately, CAC is responsible for endorsing the preparatory work for the virtual session of CCPR and CCRVDF, including the agenda, based on recommendations from the Joint EWG and the agreement of CCPR and CCRVDF. This approach ensures transparency and visibility for all Codex Members and Observers.

The effective management of compounds with dual use—as both pesticides and veterinary drugs— by Codex requires close collaboration between the Codex Committee on Pesticide Residues (CCPR) and the Codex Committee on Residues of Veterinary Drugs in Foods (CCRVDF), along with their respective risk assessment bodies: the Joint FAO/WHO Meeting on Pesticide Residues (JMPR) and the Joint FAO/WHO Expert Committee on Food Additives (JECFA).
