African swine fever (ASF) is a contagious and deadly viral disease that affects pigs and wild boar. Except for the suffering of animals, it may cause severe economic losses for the pig producers.
Lately, the disease has spread from the east through Europe and is present in for example Estonia, Latvia, Lithuania, Poland, Italy, the Czech Republic, Rumania, Hungary and Belgium, as well as in Russia, Ukraine and Belarus.
African swine fever is spread via direct contact between animals, but also via the blood and other body fluids from infected pigs and wild boar. Meat from infected animals also contains the virus and may spread ASF unless heat treated. The ASF virus is very resistant and may survive for a relatively long time in meat from infected animals even if the meat is frozen. If left-overs containing the virus are given to pigs or left in nature where wild boar may consume them, the animals may become infected. This is one of the ways the disease may spread to new areas.
The European Food Safety Authority has a practical guide on African swine fever; what it is and how to protect domestic pigs from infection:
