On 13 May 2026, the European Food Safety Authority (EFSA) published a scientific report mapping potential entry pathways for 25 vector-borne disease agents that could pose a threat to the European Union. The report, titled 'Potential entry pathways for 25 vector-borne disease agents,' assesses the likelihood of these pathogens entering the EU through various routes, including trade in animals, animal products, and non-food items, as well as through human travel and migratory birds. The findings are intended to inform EU risk managers and national authorities in prioritizing surveillance and prevention measures.
The report covers a range of pathogens, including viruses, bacteria, and parasites, that are transmitted by vectors such as mosquitoes, ticks, and sandflies. Among the agents assessed are West Nile virus, Crimean-Congo hemorrhagic fever virus, Rift Valley fever virus, and various species of Leishmania and Borrelia. EFSA's analysis considers the presence of competent vectors in the EU, the volume and origin of relevant imports, and the effectiveness of current border controls. The report does not set new regulatory requirements but provides a scientific basis for future policy decisions by the European Commission and member states.
Key trade-offs identified in the report include the balance between facilitating trade and preventing disease introduction. Stricter import controls on animals and animal products could reduce entry risk but may increase administrative burdens and costs for EU importers and third-country exporters. Conversely, maintaining open trade without enhanced surveillance could leave the EU vulnerable to emerging vector-borne diseases, particularly as climate change expands the habitat of certain vectors.
Stakeholders most impacted include EU livestock producers, who may face additional testing or quarantine requirements for imported animals; EU public health authorities, who could be tasked with enhanced vector surveillance and response planning; EU consumers, who may benefit from reduced disease risk but could see higher prices for imported goods; and third-country exporters, who may need to comply with stricter certification standards.
EFSA's report is a scientific opinion and does not carry binding legal force. It is expected to feed into ongoing EU discussions on the revision of the Animal Health Law and the EU's preparedness for emerging infectious diseases. The European Commission may use the findings to propose targeted amendments to import rules or to allocate funding for vector surveillance programs in member states.
