An African swine fever outbreak at a breeding farm for pigs, near Ruse in the north east of the Bulgaria, was confirmed on Saturday.
“All pigs on the holding, 17,000, will be culled,” a spokeswoman for the national food safety authority said.
Reuters reported that all home-raised pigs in a three kilometre quarantine zone, established around the farm in the village of Nikolovo, might also be culled.
Bulgaria has stepped up measures to prevent the spread of deadly African swine fever after reporting more than 30 cases of the disease in several regions, including border provinces with Romania, in July.
