PRAGUE, June 21 (Xinhua) -- Hundreds of turkeys at a farm in eastern Czech Republic were killed by the H5N1 bird flu virus, the State Veterinary Administration confirmed on Thursday.

    This is the Czech Republic's first case in which bred poultry has been infected with bird flu.

    Tests in the National Reference Laboratory in Prague showed that the turkeys in Zalsi, east Bohemia area of the country, were killed by the highly pathogenic H5N1 bird flu virus.

    Veterinarians believe that the turkeys bred at the farm possibly got infected through hay litter, which came from a pond and could be contaminated by droppings of birds living in the wild.

    According to local Veterinary Administration, people face no danger of the bird flu.

    Health Minister Tomas Julinek said that the country has a sufficient supply of medicines and is prepared for a possible flu pandemic.

    The Regional Veterinary Office have taken stringent measures to prevent the disease from spreading.

    Any transfers of birds from the afflicted flock have been banned, previous transfers of poultry have been checked and the turkey flock has been tightly sealed.

    A 3-km inner protection zone and a 10-km outer surveillance zone will also soon be in place.

    The remaining birds in the afflicted flock in the village of Tisova will be culled.

    The veterinary administration will check not only commercial but also private flocks within the 10-km zone.

    The case is likely to influence exports of poultry. Russia has already announced that it will limit poultry import from the Czech Republic.

    According to the latest news, another four wild birds, which were suspicious of bird flu, were found near Litomysl in east of the Czech republic.

    The died birds have already been sent to the laboratory for test.

    This is the second case in which the animals have been infected with bird flu in the country this year.
