EU Revises Pesticide MRLs for Six Substances: Implications for Food Exporters

Introduction

Pesticide residue compliance is a critical requirement for businesses exporting agricultural commodities, fresh produce, cereals, oilseeds and processed foods to the European Union (EU). Even when a pesticide has been used according to agricultural practices in the country of origin, the resulting residues must comply with the applicable EU maximum residue levels (MRLs).

In October 2026, the European Commission published Commission Regulation (EU) 2026/2289, amending the MRLs for six pesticide active substances in specified food and feed products. The substances covered are acequinocyl, deltamethrin, dodine, maleic hydrazide, pinoxaden and prothioconazole.

The revised limits affect selected fruits, vegetables, cereals, oilseeds and products of animal origin. The regulation also confirms certain previously tentative MRLs for pinoxaden in products of animal origin.

For exporters, importers, food manufacturers and agricultural supply-chain businesses, the update highlights the need to verify pesticide residue requirements at the commodity level, review existing residue-monitoring programmes and ensure that analytical testing reflects the applicable EU requirements.

Understanding Maximum Residue Levels (MRLs)

A maximum residue level is the highest concentration of a pesticide residue legally permitted in or on a food or feed commodity under the applicable regulatory framework.

In the EU, pesticide MRLs are primarily governed by Regulation (EC) No 396/2005. The regulation establishes a harmonised framework for pesticide residues in food and feed of plant and animal origin.

MRLs are generally established through assessments of authorised uses, Good Agricultural Practices (GAP), residue-trial data and consumer dietary exposure. The European Food Safety Authority (EFSA) evaluates relevant scientific evidence and provides risk-assessment opinions that inform regulatory decisions.

An MRL is not simply a universal toxicological safety threshold. It is a legally established residue limit based on the relevant regulatory assessment. Compliance must be evaluated against the applicable pesticide, commodity, residue definition and legal limit.

Why this matters: A pesticide residue that complies with the exporting country’s national limit may still exceed the applicable EU MRL. Exporters must therefore verify the destination-market requirement rather than relying exclusively on domestic pesticide-use approvals or local residue standards.

The 2026 EU Regulation: What Has Changed?

Commission Regulation (EU) 2026/2289 was adopted on 15 October 2026 and published in the Official Journal of the European Union on 16 October 2026.

It amends Annex II to Regulation (EC) No 396/2005 for six pesticide substances:

Acequinocyl: An acaricide used to control mites.
Deltamethrin: A pyrethroid insecticide.
Dodine: A fungicide used against selected plant diseases.
Maleic hydrazide: A plant growth regulator used in applications including sprout suppression.
Pinoxaden: A herbicide used in cereal crops.
Prothioconazole: A triazole fungicide used to manage selected fungal diseases.

The revisions follow evaluations of applications and supporting data, including EFSA assessments. The regulation establishes revised MRLs for specified commodities and confirms certain existing tentative MRLs for pinoxaden in animal-derived products following the submission and evaluation of confirmatory data.

The regulation enters into force on the twentieth day after publication, 5 November 2026. Exporters should verify the applicable requirements for consignments produced, dispatched or placed on the EU market around the implementation date, taking into account the final legal text and any relevant transitional provisions.

Key Revised MRLs and Affected Commodities

The following table summarises selected commodity-specific limits established by the regulation. These values are expressed in milligrams per kilogram (mg/kg), equivalent to parts per million (ppm) by mass.

This is a selection of revised limits, not a complete reproduction of Annex II. The regulation also addresses additional commodities and specific residue definitions. Businesses should consult the full legal text for the applicable commodity and pesticide combination.

Important analytical detail: residue definitions

Compliance testing must target the legally defined residue, which may include the parent pesticide, specified metabolites or a sum of compounds.

For example:

Deltamethrin: The regulation specifies deltamethrin (cis-deltamethrin).
Pinoxaden: The relevant residue definition includes the sum of M4 and M6, both free and conjugated, expressed as pinoxaden.
Prothioconazole: The relevant plant-commodity residue definition includes prothioconazole-desthio, expressed as the sum of isomers.

These definitions matter because a method measuring only the parent compound may not necessarily establish compliance with a residue definition that includes metabolites or other specified components.

What the Changes Mean for Food Exporters

The revised MRLs create a need for commodity-specific review of pesticide residue risks, particularly for exporters supplying the affected products to EU buyers.

Fresh fruit and vegetable exporters

Businesses exporting blueberries, cranberries, currants, gooseberries, kiwi fruit, melons, watermelons, grapes, celeriac, garlic, apricots, cherries and plums should review whether the updated pesticide limits affect their products.

The relevant pesticide and commodity combination must be checked individually. A change to one pesticide’s MRL does not automatically change the permitted level of other pesticide residues in the same commodity.

Cereal and oilseed exporters

The revised pinoxaden MRLs for barley, wheat and rye, together with the prothioconazole provisions for rapeseed/canola seed, are relevant to businesses exporting these commodities or using them as ingredients.

Exporters should verify residue-monitoring plans against the applicable residue definitions and the requirements of their buyers.

Rice exporters

The revised prothioconazole MRL for rice is particularly relevant to rice supply chains where this active substance may be used or where residue contamination is identified as a potential risk.

The relevant EU MRL should be checked before shipment, and testing should be selected according to the applicable residue definition and the required reporting capability.

Animal-derived food businesses

The regulation also revises specified maleic hydrazide MRLs in products of animal origin and confirms certain tentative pinoxaden MRLs.

Businesses involved in meat, offal, milk or egg supply chains should review the precise commodity entries rather than applying a single limit across all animal-derived products.

Pesticide Residue Testing: Analytical Requirements

Reliable pesticide residue testing requires an analytical method that is appropriate for the target pesticide, commodity matrix and applicable residue definition.

Multi-residue analysis using LC-MS/MS and GC-MS/MS

Liquid chromatography–tandem mass spectrometry (LC-MS/MS) and gas chromatography–tandem mass spectrometry (GC-MS/MS) are widely used for pesticide residue analysis.

Depending on the substance and validated method, these techniques can support the identification and quantification of multiple pesticide residues in a single analytical workflow. LC-MS/MS is suitable for many polar, non-volatile or thermally sensitive pesticide compounds and relevant metabolites.

GC-MS/MS is suitable for pesticides that can be analysed using gas chromatography, subject to the method’s chemical and instrumental requirements.

Neither technique automatically covers every pesticide or residue definition. The method must be evaluated for the specific analytes and matrix.

QuEChERS sample preparation

QuEChERS — Quick, Easy, Cheap, Effective, Rugged and Safe — is a commonly used sample-preparation approach for multi-residue pesticide analysis in many food matrices.

It generally involves extraction with a suitable solvent followed by partitioning and, where required, dispersive solid-phase extraction clean-up. The specific procedure may require modifications depending on the food matrix, analyte properties and method performance requirements.

Method performance and reporting limits

For export-compliance testing, method suitability should consider:

The applicable EU MRL and legal residue definition.
The analytical method’s limit of quantification (LOQ).
Recovery and precision.
Matrix effects and potential interferences.
Identification criteria and confirmation requirements.
Relevant quality-control measures.
Measurement uncertainty and the applicable decision rules.

A method with an LOQ above the relevant MRL may be unsuitable for demonstrating compliance at that level. The laboratory and exporter should confirm analytical capability before sample submission.

Sampling: A Critical Part of Compliance

Pesticide residue results are only as representative as the sample tested. Residues can vary between individual fruits, field lots, production sites, harvest dates and batches.

A robust sampling programme should consider:

Lot identification: Clearly identify the consignment, commodity, origin, production lot and relevant traceability details.
Representative sampling: Use a suitable sampling procedure for the commodity and intended compliance assessment.
Sample handling: Prevent contamination during collection, packaging, storage and transport.
Sample preparation: Ensure that the laboratory prepares the sample according to the applicable commodity-specific method and residue definition.
Documentation: Maintain traceability between the tested sample, analytical report, supplier and export consignment.

A laboratory result from one batch should not automatically be treated as proof that all other batches from the same supplier or growing region will comply.

Practical Steps to Prepare for the 5 November 2026 Implementation Date

Food exporters and manufacturers can take the following actions to prepare for the revised MRLs.

Review pesticide use and supplier information

Identify whether the six substances are used in relevant crops, ingredients or supply chains. Obtain current pesticide-use records and supplier declarations where appropriate.

Map commodities to applicable MRLs

Create a product-specific matrix linking each exported commodity to the relevant pesticide, residue definition, MRL and analytical requirement.

Update residue-monitoring plans

Review existing testing frequency and analyte lists. Include additional testing or targeted verification where the risk assessment indicates a need.

Confirm laboratory method suitability

Check that the selected method can quantify the relevant residues at sufficiently low levels and covers any required metabolites or residue sums.

Review consignments around the effective date

Confirm the applicable legal requirements for consignments moving through the supply chain around 5 November 2026. Do not assume that the date of production, testing or dispatch alone determines which provisions apply

Investigate non-compliant results

Where results exceed an applicable limit, assess sample identity, analytical validity, the relevant legal residue definition and the applicable decision rules. Investigate the source and implement corrective action before making further compliance decisions.

Maintain traceability and records

Retain test reports, sampling records, pesticide-use information, supplier documents and corrective-action records to support internal review and customer or regulatory enquiries.

Common Mistakes in EU Pesticide MRL Compliance

Exporters should avoid the following errors:

Using national pesticide limits instead of verifying the destination-market MRL.
Applying a single limit to all commodities or all pesticides.
Confusing an MRL with a pesticide authorisation or a toxicological reference value.
Testing only the parent compound when the legal residue definition includes metabolites.
Selecting an analytical method without checking its LOQ against the applicable limit.
Assuming that one compliant sample proves compliance across every batch.
Using outdated MRL tables or supplier specifications.
Treating the publication date and the date of application as interchangeable.

MRL compliance should be managed as an ongoing process involving agricultural practices, supplier controls, analytical verification and regulatory monitoring.

Conclusion

Commission Regulation (EU) 2026/2289 revises MRLs for six pesticide substances across selected plant- and animal-derived commodities. With the regulation scheduled to enter into force on 5 November 2026, exporters should review affected products, verify the applicable limits and confirm that residue-testing methods cover the relevant legal definitions.

Effective compliance requires more than testing a sample at the last stage of export. It depends on coordinated supplier controls, suitable agricultural practices, representative sampling, fit-for-purpose analytical methods and current regulatory information.

For businesses supplying food and agricultural commodities to the EU, a structured pesticide residue monitoring programme can help identify potential compliance issues early and support better-informed export decisions.
