Risk traffic light - Preface - African swine fever

The following technical recommendations are precautionary measures to prevent the introduction of ASF into domestic pig herds. They include legal requirements as well as current technical recommendations. The ASF risk traffic light is limited to ASF and is to be understood as a supplement to the requirements of the Pig Housing Hygiene Ordinance and other biosecurity recommendations. However, the recommendations do not include measures for early detection, and other requirements apply in the event of an epidemic.

 

The main risk for the introduction of ASF is considered to be the human being, who introduces the virus into the herd over long distances on his clothing (hunters!), via food from risk areas or through unsafe feed (also illegal feeding of food waste). In particular, persons (employees) from ASF risk areas can introduce the pathogen into wild and domestic pig populations via clothing, food brought in or vehicles.

Feral pigs pose a direct risk of introduction if they are infected with ASF.

ASF is not a zoonosis - humans cannot become infected or ill. In Central Europe, ASF only affects pigs.

The likelihood of ASF entering a domestic pig herd is related to the frequency of animal, person, and vehicle traffic on the farm. However, the level of protection is determined by the containment measures taken. 

This is version 1.1 of the ASF risk traffic light, published June 18, 2019,
revised January 2020.
