African Swine Fever Confirmed in Spain After Three Decades

The World Organisation for Animal Health reported on November 28, 2025, that African swine fever has been detected in wild boars found dead in Barcelona Province, Spain. The confirmation, dated November 27, 2025, marks the country’s first ASF occurrence since September 30, 1994—ending more than three decades of being free of the disease.

According to a Reuters report published November 30, 2025, the number of suspected cases has grown since the initial finding. Two wild boars tested positive initially, while an additional 12 wild boar are undergoing diagnostic testing. If confirmed, the total would rise to 14 cases.

Spanish authorities have launched immediate response measures, including surveillance and containment efforts. Several international trading partners have already restricted imports of Spanish pork, a sector valued at €8.8 billion ($10.2 billion) annually, as noted by Spain’s Agriculture Minister Luis Planas.

The re-emergence of ASF in Spain underscores the ongoing challenges posed by the virus across Europe and highlights the critical importance of continued biosecurity vigilance in protecting both animal health and global trade.
