The report by the State Service for Food Safety and Consumer Protection says at least two pigs at the farm died of the ASF, as per veterinary post-mortem examination. The farm premises, as well as the entire village hosting the business and a number of neighboring settlements, were put on quarantine on July 23.

African swine fever (Montgomery disease) is a contagious viral disease of domestic and wild pigs. The disease bears no threat to humans. The virus is transmitted by direct contact between sick and healthy animals, through pork products, and also transmitted by ticks and mechanically (by vehicles during transportation of people and animals). There are no vaccines against the virus. Almost all infected pigs die. The virus is destroyed by heating to extremely high temperatures.
