Tests on poultry found dead in Romania have showed they had the deadly H5N1 bird flu strain, officials have said.
Romania was the first country in Europe to detect H5N1 bird flu cases
Last week, Romanian authorities announced four new cases of infected domestic birds from the village of Caraorman, in the Danube delta region.
They said the village, which has no road access, would be quarantined and 2,000 birds would be slaughtered.
Romania was the first European country to detect the deadly strain of the disease in poultry last month.
The tests on four hens were carried out by a British laboratory.
"Regarding the samples in Caraorman, the laboratory in London confirmed it was the highly pathogenic H5N1 virus," Romania's agriculture ministry said on its website.
Romanian Agriculture Minister Gheorghe Flutur told news channel Realitatea TV: "We are keeping things under control."
The H5N1 virus has killed more than 60 people in South East Asia since the latest outbreak began in 2003.
Scientists believe it is only a matter of time before the virus changes and develops the ability to spread easily among humans.
