Hungary has informed the Agriculture and Fisheries Council that the emerald ash borer (Agrilus planipennis) has been detected for the first time in Hungary and therefore in the European Union, marking the first appearance of this priority quarantine pest within EU borders. The information was shared as an 'Any Other Business' item during the Council meeting of 13 July 2026, according to a Council note dated 10 July 2026.
The emerald ash borer is listed among the EU's priority quarantine pests and is considered one of the world's most destructive invasive forest insects. It has already destroyed tens of millions of ash trees in North America, causing severe ecological and economic damage. If the pest becomes established in the EU, it could threaten the long-term survival of Europe's ash populations, with major consequences for forestry, biodiversity, and landscape.
As the first affected EU Member State, Hungary now plays a decisive role in preventing the pest's spread within the Union. Successful eradication will require coordinated action by domestic and international organisations, as well as rapid and consistent implementation of phytosanitary measures. The Council note does not specify the exact location or extent of the infestation in Hungary, nor does it outline any immediate EU-level response. However, the detection triggers obligations under EU plant health law, which requires Member States to take immediate eradication measures against priority pests.
The development places Hungary at the centre of EU efforts to contain the pest, and the Commission and other Member States are expected to follow up with technical support and possible emergency measures. The detection also raises concerns for the EU's forestry sector, which relies on ash trees for timber production and ecosystem services, and for environmental NGOs focused on biodiversity conservation. The economic impact could be significant if the pest spreads, given the costs of tree removal, replanting, and loss of ecosystem services. On the other hand, swift and effective eradication could minimise long-term damage, protecting both the environment and the forestry industry.
