| Passive surveillance of African Swine Fever (ASF) in wild boars as an effective tool for prevention, control and eradication of ASF: A new approach |
| The latest recommendations of the European Commission and the scientific opinions of the EFSA and other bodies define the passive surveillance of ASF in wild boars as a key means of epidemiological surveillance and a basic tool for the eradication of the ASF virus from the natural environment in the areas where this disease occurs, especially in the early stage of its development. The key to eradication is the management of the wild boar population and its reduction to a low and controlled number, so as to diminish the virus pressure in the environment and lessen the risk to pig farms. Wild boar hunting should take place in a planned manner that is adapted to the epizootic situation (as part of centrally managed hunting and sanitary culling). The most intensive hunting should take place in ASF-free areas, with the use of tailored methods and the latest technologies. Periodic hunting moratoria and restrictions on any activity in newly infected zones are necessary. This approach provides for phased eradication of the infectious agent by culling or capturing wild boars, as well as identifying and safely removing their carcasses and remains. When passive ASF surveillance in wild fauna is undertaken, data on the incidence of the disease in wild boars are obtained by the Veterinary Inspectorate without its active participation. The inspectorate is notified of any suspicion or occurrence of the disease, including discoveries of carcasses of animals of susceptible species. Then it acts according to an established plan including clinical examination of suspected or sick animals, anatomopathological examinations and sample collection for laboratory tests. The article describes the use of passive ASF surveillance in wild boars as a tool to prevent, control and combat ASF in Poland. |
