Nature today African swine fever: prevention is better than lowering



If the pig population is infected with African swine fever (AVP), about 99 to 100 percent of the pigs present have died. AVP is therefore a very serious threat to domestic wild boar populations in the Netherlands. In addition to our autochthonous beaver populations, disease is also a serious threat to pig breeding in the Netherlands. If the virus appears in the Netherlands, it will have major ecological and economic consequences, and even now, before the disease has been discovered in the Netherlands, the consequences have already been observed, for example, allowing the hunting method and allowing the use of silencers in wild boar hunting. This fact has led the Mammals Society to formulate an attitude on how to deal with the danger of AVP based on the starting points of the Mammals Society and to specifically identify what actions are needed to pig population in the sustainable future of the Netherlands. .

Prevent human infection: hygiene

The most important ways of contamination are people's activities. Therefore, the prevention of outbreaks is mainly to prevent contamination of wild boar with AVP human activities. In order to prevent contamination of wild boar, but also to keep pigs with AVP, it is important to avoid contact with wild pigs by not entering the habitat of species outside the path. If access to a habitat outside the paths and pathways in connection with administrative activities, hunting, research or other procedures is required, they operate under strict hygienic protocols and clean clothes and training thereafter.

Prevent animal infection: double mesh

The most important route of contamination of pigs and wild boar is man, but contamination from animals to animals is also possible. Therefore it is very important to keep pigs separate from wild boar, for example, double fences. Open agricultural systems must invest in isolation and double fences as much as possible, as keeping pigs kept is not a structural measure. The performance of pigs is a crucial part of the company's philosophy for open farms and is socially desirable.

Also, hobby pigs must be well protected.

Battlefield Infection: Isolate contaminated habitat

If populations of wild boar are contaminated with AVP, the Czech approach is a good measure: isolation / isolation of the habitat of contaminated wild boar. This prevents the spread of infected pigs and maximizes rest in some area. Therefore, the improvement of the additional degree is counterproductive. Keeping the silence in place prevents the infected boar from hunting and ending out of the protected habitat. Population within the protected area must be considered lost. Pigs will almost all die from AVP. The remaining boar must also be released over time to eradicate the virus.

In short: prevent the introduction of the virus and isolate it quickly after infection

In short, the attitude of the Mammal Society is that everything must be done to prevent the contamination of wild boar with AVP. The greatest attention should be paid to the "pathways of human infection" because the greatest risk lies in this area. If AVP is still detected in the pig population, rapid and strict isolation of the habitat is necessary. If a subsequent degree is required subsequently, it must be done or under the guidance of professional organizations such as site managers or (pole) authorities. In the event of a population decline, methods such as food cages should have priority over descent. The current threat from AVP calls for the preparation of (renewed) area of ​​wildlife management plans. For this, the provinces are responsible.
