Abstract
= 24) were identified via systematic testing of two dead pigs per week. Overall, 518,088 samples from domestic pigs were analysed in the EU in 2025. In wild boar, the number of outbreaks notified in the EU increased from 7677 in 2024 to 11,036 in 2025, marking a change from the relatively stable situation of 2022-2024. Poland and Germany accounted for 31% and 18% of the total, respectively. Similarly to previous years, a winter seasonality in wild boar was observed in several Member States. Overall, 28% of the 44,578 wild boar carcasses tested positive for ASFV by polymerase chain reaction (PCR), representing 71% of wild boar outbreaks notified in the EU. In contrast, 1% of the 531,832 hunted wild boar tested positive by PCR, representing 27% of wild boar outbreaks. Despite the higher number of ASF outbreaks, the average size of the area under restriction in the EU due to outbreaks in domestic pigs increased only slightly in 2025 (+2%), while the average size of the area under restriction due to outbreaks in domestic pigs and in wild boar remained at a similar level as in 2024.
