Table 1.

The eight main EFSA scientific opinion founding [9] are identified by the main scientific key points and summarized as the indicator and the specification of these founding.

Key Points Indicator Specification
1 Land subdivision Extension of the area (km2) The exit strategy should be evaluated based on a portion of territory (i.e., LAU1, or HMU)
2 Active surveillance performance Number of months covered by active surveillance, probability of false decision The exit strategy to be applied in a specific area should be evaluated based on the combination of both active and passive surveillance, during which all hunted wild boar must be ASF tested. The inclusion or omission of active surveillance determines a shorten or longer period to make decisions and strategy performance in terms of the probability of a false decision
3 Number of samples expected—screening phase Found dead animals expected to be found in a specific area by the extension of the area during the screening phase During the screening phase, a total of one carcass/1000 km2/year should be found. Only found dead wild boar must be counted as valid carcasses, not wild boar killed by traffic accidents
4 Screening phase—month count Number of months after the last ASFV PCR+ detection in each area The screening phase starts from the last ASFV detection
5 Screening phase—carcasses found Number of carcasses found during the screening phase in each area During the screening phase, passive surveillance aiming to detect at least one carcass/1000 km2/year must be applied
6 Number of samples expected—screening phase Animals found dead expected to be found in a specific area by the extension of the area during the confirmatory phase During the confirmatory phase, a total of one, two, or six carcasses/1000 km2/year should be found. Only wild board found dead must be counted as valid carcasses, not wild boar killed by traffic accidents
7 Confirmatory phase—month count Duration of the confirmatory phase (months) in each area The confirmatory phase starts after the screening phase, and its duration depends on the level of confidence and the duration of the screening phase
8 Confirmatory phase—carcasses found Number of carcasses found during the confirmatory phase in each area During the confirmatory phase, enforced passive surveillance aiming to detect at least one, two, or six carcasses/1000 km2/year must be applied
