Disinfection - an integral part of preventing the spread of African swine fever
African swine fever (ASF) is a highly contagious viral infection of pigs. African swine fever virus (ASFV) is the sole member of the genus Asfivirus. Genome of virus is encoded more than 160 proteins. It is known 22 different genotypes with different virulence. African swine fever virus is highly resistant to low temperatures, variability pH and remains viable for long periods in tissues and body fluids. Virus is transmitted by arthropods. Pigs are infected mainly through the oro-nasal route after contact with infected pigs, contaminated feed, clothing, footwear, equipment and vehicles. The virus is inactivated by heat treatment by temperature of 70 oC for at least 30 min and by pH 11.5. The work is focused on the analysis of potential disinfection options as an integral part of the preventive measures against the spread of African swine fever virus including the elimination of its sources, possible vectors and the adaptation of the environment to prevent its multiplication and spread. Common disinfectants are ineffective against the African swine fever virus, so there should be used only effective approved disinfectants with minimal residuals effects to the environment. The ASFV is susceptible to ether and chloroform. The destruction of African swine fever virus was recorded on non-porous surfaces using sodium hydroxide, sodium hypochlorite, citric acid, certain iodine based preparations and quaternary ammonium compounds.
