Situation in Belgium

Identification of African swine fever (ASF) in wild boars in Belgium

For more detailed information please consult the document “African swine fever” virus in wild boar in Belgium (link).

  • OIE official attestation: self-declaration "free status of ASF for domestic and wild pigs kept in captivity"

  • Initial attestation of the CVO EN - FR (13/09/2018)

  • Renewed attestation of the CVO EN - FR (02/12/2019)

Up until the 3rd of December 2019, 4340 carcasses of wild boar have been analyzed for ASF, among which 829 have been confirmed positive for African swine fever (ASF). All the infected carcasses are located within the zone II.

The last 2 cases were confirmed on the 21st of October and 13th of November 2019.

These cases were confirmed on the remains (only bones) of 2 wild boar. The bones were dry and completely emaciated when found in open air. These bones were tested twice by the NRL for remnant wild boar DNA, and the results were negative both times. This allows us to conclude that these latest cases concern wild boar that died more than 6 months ago, meaning before May 2019.

The previous case was confirmed on the 14th of August 2019.

Based on the literature, the impossibility of demonstrating in the laboratory the presence of a remnant of the wild boar's DNA (negative beta-actin) in a bone found in the open air indicates that more than 6 months have elapsed since the death of the animal (cf. article "porcine bone samples/left in open-air" - Biomedical Reports).

There are no outbreaks in domestic swine.
No domestic and captive swine remain in the initial infected zone (decision of the Federal minister of Agriculture to eradicate all domestic swine by 2 October 2018).
Strict measures have been taken for the whole country to prevent contamination of domestic swine.

Based on European legislation and following consultation with the federal authorities and regional Walloon authorities, the initial "infected zone" has been replaced on the 27th of November 2018 by two separate zones: "Zone I" and "Zone II". This formal decision is imposed by European legislation in the context of zoning and protection measures against ASF, according to the identified risk. (see map below).

Important to know

  • African swine fever is limited to wild boars in a small area of the southern part of Belgium, there are no outbreaks in domestic swine, and the necessary and preventive measures are taken to control and avoid dissemination of the disease.

  • All domestic swine in the initial infected zone has been eradicated under the supervision of the FASFC and the repopulation of farms in this zone is forbidden. No products of these eradicated swine entered or will enter the food chain or will be used in the feed industry.

  • Notwithstanding, the certification conditions laid down in the relevant protocols concluded between Belgium and the non-EU countries (third countries) will be scrupulously respected.

  • Taking into account the definitions included in Chapter 15.1.3 of the OIE Terrestrial Code, Belgium lost its disease-free status for African swine fever in all suids. Belgium currently still has a free status for domestic and wild pigs kept in captivity.

  • Measures are taken as provided in Article 15 of European Union Directive 2002/60/EC and supplementary national regulations. The detailed information about these measures can be found in the following document.


On the 13th of September 2018, African swine fever (ASF) virus was confirmed for the first time since 1985 in 2 wild boars in the municipality Etalle (province of Luxembourg). In this region very few domestic pigs are kept (most swine farms are located in the northern part of Belgium).

The Federal minister of Agriculture has decided to eradicate all domestic swine in the infected zone by 2 October 2018. It must be made very clear that his is merely a preventive eradication to prevent the contamination of domestic swine and to protect animal health and the commercial interests of the Belgian Pork industry. It is certain that products of these eradicated swine will not enter the food chain or be used for the feed industry. Compensation for the destroyed domestic swine of all affected farmers will be provided by the Sanitary Fund (Belgian) and European funds, reserved for animals disease outbreaks. Other economic compensation will be provided by the Walloon Region.

It should be emphasized that the potential risk lies in the spreading from wild boars to domestic and captive wild pigs, but that this risk is very limited since the necessary measures are taken.
