Police Investigation At The IRTA-CRESA Laboratory For African Swine Fever In Cerdanyola Del Vallès.

The Mossos d'Esquadra (Catalan police) and the Guardia Civil (Spanish Civil Guard) conduct an investigation at the IRTA-CRESA laboratory in Cerdanyola del Valles, Spain, on December 18, 2025, into African swine fever. The first positive cases of African swine fever in wild boar are found very close to the laboratory, and the main hypothesis is that the virus may have originated there.
