The INC participated in the 57th Session of the Codex Committee on Pesticide Residues (CCPR57), which was held in Beijing, China, from September 7-12, 2026.
INC members are invited to contact us with feedback on any of the issues addressed at this meeting.
In contrast to previous years, few new approaches were discussed at this CCPR. The review of older, existing Codex Maximum Residue Limits (CXLs) has become more of a priority. Older compounds often either have critical uses in specialty (minor) crops, and/or are still manufactured and used outside of the Western world. If there is no sponsor and there are human health concerns, then any existing CXLs will be cancelled after four years of seeking a sponsor. There is frustration that sponsors may speak up at the last minute promising data in a year or two, thus extending the process to well beyond four years. Some countries are trying to find a way to assess existing CXLs for health concerns to see if can get to faster removal, while others are trying to hang on to the older compounds.
This process was applied to the insecticide phosmet (see below), for which the Joint FAO/WHO Meeting on Pesticide Residues (JMPR) had recently lowered the acute reference dose. At the last CCPR, JMPR was asked to conduct a “screening”-level assessment—that is, no refinements in the assessment. According to that assessment, while the tree nut and cottonseed CXLs were suitable, the citrus and pome fruit CXLs would not be (cranberry was not reassessed). There was much debate within the plenary regarding to what extent a screening-level assessment should be used for decision-making. The registrant is supporting the tree nut, cottonseed and citrus CXLs. Ultimately, it was decided to await the full JMPR review of the residue data submitted by the registrant.
The Codex Secretariat also spent time reviewing plans to completely overhaul their website and how Codex standards are listed. The hope is to both update outdated language and to develop a much more flexible system that will allow more timely updates.
Discussions and decisions affecting nuts and dried fruits included the following:
New Codex MRLs:
- Bifenthrin: Cranberry CXL 1.5 ppm moved to step 5/8. Reservations were noted.
- Cyfluthrin/beta-cyfluthrin: Dried grapes CXL at 1.5 ppm moved to step 5/8. Reservations were noted for the table grape CXL, but not for dried grapes.
- Mefentrifluconazole: CXL for dried grapes at 15 ppm moved to step 5/8.
- Proquinazid: CXLs for dried grapes at 1.5 ppm. Reservations were noted.
- Pyriproxyfen: CXLs for prunes at 0.9 ppm, dried grapes at 4 ppm, peach/nectarine at 0.5 ppm moved to step 5/8.
New Uses / New Registrations Planned:
- Propylene oxide: Propylene oxide was included in the 2027 schedule for JMPR evaluations for a new use on tree nuts.
- Tebuconazole: 2027 JMPR. New uses: Peach subgroup (apricots).
- Prothioconazole: 2027 JMPR. New uses: stone fruit (except peach), grapes, pome fruit.
- Feneptamidoquin: New active ingredient, 2028 JMPR. Proposed tree nuts.
- Acequinocyl: New active ingredient. 2028 JMPR. Proposed tree nuts.
- Clothianidin/thiamethoxam: 2028 JMPR. Iran has proposed to submit data for an updated pistachio CXL.
- Pyrazifluamid: 2028 JMPR. New uses: Tree nuts, stone fruit.
- Spidoxamat: 2028 JMPR. New uses: Cranberry.
- Cyclobutrifluran: 2028 JMPR. New uses: Peanuts, tree nuts.
- Isocycloseram: 2028 JMPR. New uses: Cranberry.
- Flupyradifuron: 2028 JMPR. New uses: Tree nuts.
CXLs Revoked:
- Disulfoton: All existing CXLs to be revoked. If accepted by the CAC in July 2027, then the revocation date is one year later. Includes CXLs for peanut and for pecans at 0.1 ppm.
CXLs Under Periodic Review / Lacking a Sponsor:
- 2,4-D: Up for periodic review at 2027 JMPR. CXLs include tree nuts (0.2 ppm).
- Acetamiprid: Planned for periodic review by JMPR in 2028. Current CXLs include prunes (0.6 ppm), pistachio (1.0 ppm), tree nuts other than pistachio (0.06 ppm).
- Carbaryl: Currently scheduled for periodic review for the 2029 JMPR. However, a concern form about all the existing CXLs was submitted and JMPR will review at their 2026 meeting. If JMPR finds health risks of concern, it may come to the 2027 CCPR for consideration. Current CXLs include tree nuts (1 ppm) and cranberry (5 ppm).
- Clethodim: Under periodic review. To be evaluated at the 2027 JMPR, so current CXLs are retained until that review is completed and outcomes are to be reviewed at the 2028 CCPR. CXLs include peanuts (5 ppm). It is not clear if the registrant is supporting peanuts.
- Dithiocarbamates (mancozeb, ziram, mitiram, thiram, propineb): Under periodic review starting with toxicological reviews of mancozeb and metiram in 2028, of propineb in 2029, and of ziram and thiram in 2030. The CXLs will be reviewed in 2030. Current CXLs include almonds, pecans, peanuts (0.1 ppm), cranberry (5 ppm) and stone fruit (7 ppm). There is not a walnut CXL, but it could be added or a tree nut crop grouping could be obtained.
- Endosulfan: Up for periodic review in 2028. To date no sponsor has promised data. Current CXLs include hazelnut (0.02 ppm).
- Fenbutatin oxide: Up for periodic review. To date no sponsor has promised data, but the registrant did ask for one more year to evaluate if they have the data/resources to submit a package. Current CXLs for almonds, walnuts, pecans (0.5 ppm) and raisins (20 ppm) could be recommended for deletion at next CCPR unless there is a sponsor with data.
- Flutriofol: Under periodic review. To be evaluated at the 2026 JMPR. Current CXLs include almonds (0.8 ppm), dried grapes (2 ppm), peanuts (0.15 ppm) and prunes (0.0 ppm).
- Hydrogen phosphide (phosphine): Support is uncertain. It was to be reviewed at the 2025 JMPR, but it seems data was not submitted. Existing CXLs include dried fruit, tree nuts and peanuts (0.01 ppm).
- Metalaxyl: Under periodic review. To be evaluated at the 2026 JMPR.
- Methiocarb: Up for periodic review in 2028. To date no sponsor has promised data. Current CXLs include hazelnut (0.05 ppm).
- Methyl bromide: A data sponsor for methyl bromide has stepped up and promised both toxicological and residue data for the 2027 JMPR (at least toxicological data). To recap, at the 2025 CCPR meeting, the Codex Secretariat noted that the existing CXLs for methyl bromide had not been properly established. Thus, last year’s Codex Committee moved them to Step 4, as if a new compound, rather than revoking them. Given the importance of methyl bromide for quarantine and pre-shipment applications and disease control, as well as its continued authorization for use in some countries, members indicated that retaining the proposed MRLs would facilitate trade. Current old, now proposed CXLs include dried fruit (2 ppm at import / 0.1 ppm at retail), peanuts and tree nuts (10 ppm at import / 0.01 at retail).
- Permethrin: Up for periodic review. JMPR did the toxicity assessment, but residue data was not submitted as promised. The registrant promised residue data for the 2027 JMPR. The EU recommended revoking at this time, but the plenary decided to retain until data is evaluated (or not submitted by the December 2026 deadline for 2027 JMPR). CXLs include almond, peanut (0.1 ppm), pistachios (0.05 ppm) and grapes (2 ppm).
- Phosmet: Under periodic review (see discussion above) and JMPR substantially lowered the allowable acute reference dose. CCPR57 agreed to retain the CXLs for phosmet in tree nuts awaiting additional data submission and a full evaluation by JMPR in 2028 (and thus CCPR59 decision). However, the existing pome fruit CXL is unlikely to pass unless there are changes to the use pattern (GAP) and thus a lower CXL. The registrant is still assessing whether it can support this. If it cannot, the CXL will likely be revoked at the CCPR meeting in 2027.
- Piperonyl butoxide: Up for periodic review at 2027 JMPR. Current CXLs include dried fruit (0.2 ppm) and peanut (1 ppm). There is not a CXL for tree nuts, but an opportunity to add one for tree nuts.
- Propargite: Planned for periodic review by JMPR in 2028. It is not clear what CXLs will be supported. Currently CXLs include almond, peanut (0.1 ppm), walnut (0.3 ppm) and dried grapes (12 ppm).
- Quintozene: Up for periodic review at 2027 JMPR. Current CXLs include peanut (0.5 ppm).
Existing CXLs can be revoked after 4 years of being put up for review if no sponsor steps up to provide data. CXLs can also be revoked if the review of the toxicological data indicates that lower toxicological endpoints should be used. Then some CXLs, especially with higher maximum levels, no longer can make a safety finding and thus the existing CXLs are revoked.
Final decisions regarding the actions discussed at CCPR57 will be made at the next Codex Alimentarius Commission meeting (CAC50), which will take place in July 2027. Any CXLs at step 5/8 are up for final adoption at the next CAC. The next CCPR will move back to the May/June time frame, allowing CCPR decisions to be up for adoption more quickly at the CAC.
