Recently, African swine fever (ASF) was introduced in the EU (Lithuania and Poland). Given these circumstances, the Scientific Committee was asked to give a rapid advice on the possible introduction of ASF in Belgium. More specifically, it was asked to identify the risks for the introduction of the ASF virus and to investigate the need for additional measures in order to prevent the introduction of the virus in Belgium and to detect a potential introduction at an early stage. The Scientific Committee has listed all possible ways of introduction of ASF and has assigned them a score according to their risk for the introduction of ASF in Belgium. This analysis shows that the risk for introduction of ASF in Belgium is as yet low, but not non-existent. As a general rule it can be said that blood and all products that contain blood (e.g. meat) are the main source of infection and therefore the highest risk for introduction. According to the Scientific Committee, the main risks lie in economic migration from Eastern Europe and hunting tourism followed by general tourism and intra-Community trade of Suids and derived raw or frozen products originating from infected regions. ; BE; fr; secretariaat.scicom@favv-afsca.be
