EU Regulatory Correction on Preventive Veterinary Medicines: What Changes for Farmers and Veterinarians

Key data

Farmers and veterinarians applying preventive protocols against animal diseases included on the European list must urgently review their procedures. The correction of errors in the Delegated Regulation (EU) 2026/1073, published in the Official Journal of the EU on May 13, 2026, remedies technical inaccuracies in the rules governing the use of veterinary medicines for preventive purposes and disease control.

This correction amends the Delegated Regulation (EU) 2023/361, which in turn complements the Regulation (EU) 2016/429 on animal health. The regulatory chain is relevant: any error in the base text is directly transferred to the operational protocols of the sector.

What does this regulation establish?

Regulation (EU) 2016/429 is the European animal health framework. On it are built delegated regulations that specify technical aspects, such as the use of veterinary medicines to prevent and control diseases included on the European list of notifiable diseases.

The Delegated Regulation (EU) 2023/361 established specific rules on which medicines can be used, under what conditions and for which diseases on the list. Subsequently, the Delegated Regulation (EU) 2026/1073 amended and corrected that text. Now, the correction of errors published on May 13, 2026 remedies technical inaccuracies detected in that latest delegated regulation.

The corrections are technical in nature and directly affect the letter of the protocols that sector operators must follow. Working with the text prior to the correction implies applying rules that are no longer valid.

Economic and operational impact

Although this is a correction of errors and not a policy change, the operational impact is real and immediate. Technical corrections in veterinary regulations can affect:

• Preventive medication protocols applied in livestock farms: if the corrected text modifies conditions of use, authorized doses or covered diseases, current protocols may become outdated.
• Health records and documentation: operators are required to document the use of veterinary medicines. If protocols are based on a text with errors, the documentation may not comply with the current regulation.
• Official inspections and controls: veterinary health authorities apply the current regulation. A farm working with protocols based on the text prior to the correction may be subject to observations or requirements during an inspection.
• Responsibility of the prescribing veterinarian: the veterinarian who prescribes preventive medicines must do so in accordance with the current text. The correction of errors modifies that reference text.

The cost of not updating protocols is not only economic: in animal health, regulatory non-compliance can result in restrictions on animal movement, suspension of authorizations or loss of export certifications.

Who does it affect?

• Clinical and farm veterinarians: must prescribe and apply preventive medicines in accordance with the corrected text.
• Farmers and animal farm owners: responsible for ensuring that their farm's protocols are updated and documented.
• Animal sector operators: collection centers, transporters, commercial operators managing animals subject to health controls.
• Veterinary health authorities: must apply and inspect in accordance with the corrected text from May 13, 2026.
• Agricultural advisors and consultants: who develop or supervise health protocols for their clients.

Practical example

A pig farm with a preventive vaccination protocol against a disease included on the European list has its procedures documented in accordance with Delegated Regulation (EU) 2023/361 in its version amended by RD 2026/1073. If the correction of errors published on May 13, 2026 modifies any technical condition of that protocol (for example, the specification of a covered disease or a condition of use of the medicine), the responsible veterinarian must update the written protocol and the farm's documentation.

In an inspection after May 13, 2026, the health authority will apply the corrected text. If the farm's protocol does not reflect the corrections, a remediation requirement may be generated or, depending on the severity of the discrepancy, an administrative infraction. The preventive action is simple: download the corrected text, compare it with the current protocol and update the documentation.

What should companies do now?

1. Download the corrected text from the Official Journal of the EU (OJ:L_202690491, published on May 13, 2026) and compare it with Delegated Regulation (EU) 2026/1073 that you had as reference.
2. Review the preventive medication protocols in force on the farm or with advised clients, identifying if any technical condition has been modified by the correction.
3. Update the farm's health documentation to reflect the regulatory text in force from May 13, 2026.
4. Inform the farm's responsible veterinarian so they can validate the updated protocols and, if appropriate, issue new prescriptions or instructions in accordance with the corrected text.
5. Consult with regional veterinary health authorities if there are doubts about how the correction affects specific diseases or medicines in your livestock herd.
