Blue tongue in the EU: what changes for livestock farmers and veterinarians in 2026

Key data

If you have ruminant livestock farms in the EU, this regulation affects you directly. The Implementing Regulation (EU) 2026/169, published on 27 January 2026, amended the annex to the Regulation (EU) 2018/1882 to categorise infection with blue tongue virus (serotypes 1 to 24) as a listed disease under European animal health regulations. The corrigendum published on 13 July 2026 does not alter the substance of those obligations: its sole purpose is to ensure the legal coherence of the regulatory text.

In practical terms, this means that the classification is already consolidated and the obligations it entails are enforceable. Any operator in the livestock sector that has not adapted its surveillance and notification protocols is exposed to consequences in the event of an outbreak or inspection.

What does this regulation establish?

The EU's "listed diseases" system, regulated by Regulation (EU) 2016/429 on animal health, classifies animal diseases according to their impact and the control measures required. Being on the list implies a mandatory regime of action for Member States and private operators.

The classification of blue tongue (serotypes 1-24) as a listed disease entails the following specific obligations:

• Active surveillance: Livestock operators and competent authorities must maintain surveillance programmes to detect the presence of the virus in their farms and areas.
• Mandatory notification: Any suspicion or confirmation of a case must be notified to the competent animal health authorities within the timeframes established by animal health regulations.
• Control measures in case of outbreak: In case of confirmation, restrictions on animal movement are activated, sanitary slaughter if appropriate, and restricted area measures.
• Legal coherence guaranteed: The corrigendum published on 13 July 2026 ensures that the text of Regulation 2026/169 is legally coherent, without modifying any of the obligations already established.

Economic and operational impact

The corrigendum itself does not generate new costs. However, the consolidated classification of blue tongue as a listed disease has real economic and operational implications for the livestock sector:

• Surveillance and biosecurity costs: Farms must maintain active detection protocols, which may involve periodic veterinary costs and laboratory analysis.
• Commercial restrictions in case of outbreak: The activation of restricted area measures can paralyse animal movements and intra-community trade, with direct impact on income.
• Vaccination as a preventive tool: In areas with a history of virus circulation, vaccination can be a cost-effective measure to avoid more costly restrictions.
• Strengthened legal certainty: The corrigendum provides certainty about which regulatory text is applicable, reducing the risk of divergent interpretations in inspections or litigation.

Who does it affect?

• Sheep farmers: Sheep are the animals most susceptible to blue tongue and those with the highest mortality in outbreaks. Highest surveillance priority.
• Goat farmers: Goats are also included in the scope as susceptible ruminants.
• Cattle farmers: Cattle frequently act as a reservoir without severe symptoms, but are subject to the same surveillance and notification obligations.
• Farm and clinical veterinarians: They are the first link in the detection and mandatory notification of suspicions.
• Animal health authorities of Member States: Responsible for implementing and supervising surveillance programmes and control measures.
• Live animal transport and trade operators: Movement restrictions in affected areas directly impact their activity.
• Slaughterhouses and processing plants: Must adapt their protocols for receiving animals from areas with active restrictions.

Practical example

A sheep farm with 500 head in a region of southern Spain detects animals with symptoms compatible with blue tongue: fever, facial swelling and lameness. Since blue tongue (serotypes 1-24) is classified as a listed disease under Regulation (EU) 2018/1882 as amended by Regulation 2026/169, the farm's veterinarian has the obligation to notify the suspicion to the competent authority immediately.

If the case is confirmed, the authority may establish a restricted area around the farm, blocking animal movements to other Member States or national markets. This may result in the paralysis of scheduled sales and direct economic losses for the farmer, regardless of the fact that the corrigendum published on 13 July 2026 is a technical adjustment of the regulatory text: the obligations and consequences are the same.

This example illustrates why having active and up-to-date surveillance protocols is not only a legal obligation, but also an economic protection for the operator themselves.

What should companies do now?

1. Review farm surveillance protocols: Confirm that written procedures exist to detect and record symptoms compatible with blue tongue in sheep, goats and cattle.
2. Verify notification channels with the official veterinarian: Ensure that the farm's veterinarian knows the procedure and mandatory notification timeframes for suspicion of listed disease.
3. Assess the vaccination status of the herd: In areas with risk of virus circulation, evaluate with the veterinarian the advisability of preventive vaccination programmes.
4. Update animal movement records: Keep traceability of entries and exits up to date, as in case of outbreak the authorities will require this information immediately.
5. Consult the consolidated text of Regulation (EU) 2018/1882: Verify that the internal reference version incorporates the amendments of Regulation 2026/169 and this corrigendum, to avoid applying an outdated text.
