Here, the resistance of African swine fever virus (ASFV), to inactivation was analyzed in the context of continuous danger of spreading the disease among swine herds in Poland. According to EFSA, ASFV is extremely resistant under environmental conditions. It can be inactivated by heating at 60ºC for 30 minutes and by commercial disinfectants: 1% formaldehyde within 6 days and 2% NaOH within 1 day. ASFV infectivity remains stable over a wide pH range, from 4 to 13. In the contaminated pig pens and in slurry it may survive up to 65ºC, for one month. This virus can also persist over months or years when frozen or stored at 4°C. This article presents important facts related to the ASFV control and eradication.
