Studies conducted by scientists from the University of Kansas (USA) showed that ASF virus can be easily transmitted by the natural use of contaminated feed or liquids in animals.

Another way to spread the virus is through certain methods of agricultural processing of feed ingredients used in some countries with African swine fever. As an example, scientists cited the practice widespread in China to dry crops on the roads. There is a risk that these roads are contaminated by vehicles transporting infected animals.
Also, the source of infection can be the processing of feed ingredients on already contaminated equipment, which is a potential source of transmission of viruses to animal feed.
As you know, African swine fever (ASF) is a viral disease of pigs, which is highly likely to be transmitted from patients to healthy ones, characterized by fever, bluish skin color and extensive hemorrhages in the internal organs.
The causative agent of the disease is a DNA-containing virus that is resistant to drying and decay, capable of being stored in animal corpses from 17 days to 70 days, and up to 160 days in feces. In the ground, it can persist from 112 to 200 days.
