Abstract
African Swine Fever (ASF) is one of the most important and serious contagious haemorrhagic viral disease of domestic pigs and wild boar, associated to high mortality rates and great sanitary and socioeconomic impact on international trade in animal and swine products. The early detection of the disease is often hampered by an inadequate surveillance. Among the surveillance strategies, passive surveillance of wild boar was considered the most effective for controlling African swine fever virus (ASFV). Otherwise, the design of a sufficiently sensitive ASF surveillance system re-quires a solid understanding of the epidemiology related to the local eco-social context, especially in absence of virus detection. Even if the number of carcasses needed to demonstrate the ASF eradication has been established, the scientific context is poor of details on protocols applied to active search the wild boar carcasses. The aim of the study was to describe the strategy applied for passive surveillance implemented in Sardinia, providing detailed information on the protocol applied in the field in term of number of people, dogs, time and space used to active search car-casses in the Mediterranean area. Using a specific tool developed to record, trace, and share on field data (GAIA Observer App), a total of 33 activities for active search the wild boar carcasses were organized during 2021-2023. Most of these activities were planned to find carcasses previously reported by hunters. A total of 24 carcasses were found, only 2 carcasses were not previously reported. The final protocol applied involved 4 people, with an average speed of 1.5 km/hour. When the carcass was reported, about 2 km of distance should be covered in about 1.5 hours to find the carcasses, and even less time was spent when the dog (not trained) was present. In conclusion, it can be stated that for searching for carcasses it is first mandatory a good collaboration with hunters or other forest visitors to report the carcasses, and involve small groups of expert people to active search the carcasses, possible with the use of hunting dogs with no special training.
