The highly contagious virus, which is harmless to humans, poses a significant threat to Spain's vital pork export industry, the largest in the European Union.
Catalonia is intensifying its wild boar culling efforts, with regional leader Salvador Illa highlighting the urgent need to reduce the population.
Officials suspect the virus may have spread after a wild boar consumed contaminated food, possibly from a truck driver.
Spain is actively negotiating with international buyers, including Canada, to maintain pork exports from unaffected regions, following agreements with China and Britain.
