PVD spokeswoman Ilze Meistere told BNS that the ASF was confirmed at the farm in Nagli district, the municipality of Rezekne, in south-eastern Latvia.
In total, 12 pigs were culled. Precautionary measures have been taken to prevent the infection from spreading further.
The last time a domestic pig tested positive for ASF in Latvia was on September 1 this year.
African swine fever is an extremely dangerous and contagious virus infection affecting pigs. If an infected pig is found in a farm, all pigs in the particular farm have to be culled, which means big losses for farmers.
