While much of the recent focus on African swine fever (ASF) has been focused on the continually changing situation in China, eastern and central Europe has been struggling with ASF in wild boar and domesticated swine for longer.


Now, the European Food Safety Authority (EFSA) has published an update on the epidemiological situation of ASF in Europe. In the latest report, experts assess the effectiveness of different measures that can be taken when a case of ASF is detected in an area that was previously disease-free and is far from affected areas.


Using a simulation model, the EFSA experts concluded that early detection coupled with the application of measures such as quick removal of carcasses and intensive hunting in the specially designated hunting areas increases the probability of eradication.


EFSA said the experts also observed seasonal peaks in the numbers of animals that tested positive and were found dead summer and winter for wild boar and summer for domestic pigs.


The report calls for more research to understand the causes of the introduction of ASF in pig farms and how this can be prevented, EFSA said, noting that it also recommends control options for different scenarios such as in non-affected areas close to or far away from affected areas or where the disease has been present for more than one year.
