Latest test results appear to have ruled out the existence of the deadly H5 or H7 bird flu virus strains in samples taken from dead birds in a village in southern Bulgaria, Agriculture Minister Nihat Kabil said on Friday.
But Kabil said the final results would be known in 10 to 14 days following tests at a European Union laboratory in Britain, the state-run BTA reported.
Local authorities have culled all poultry in the affected area around the village of Slanchogled, where mass deaths among domestic birds were reported, said the BTA.
The government is to begin compensating the owners of the culled birds for their losses on Monday.
All residents in Slanchogled will be examined, and the first of two disinfection programs were launched in the village on Friday. Birds in nearby population centers are also being monitored.
The Bulgarian authorities confirmed the first case of bird flu in domestic fowl in Slanchogled on Thursday, one day after 107 hens and turkeys were found dead in the village.
