Flocks of birds belonging to three farming families in Svay Chrum district?s Bassac commune have been destroyed by officials as part of efforts to contain the spread of the virus, said Thach Rotana, director of the provincial agriculture department.

Prompted by the sudden deaths of 68 birds, local authorities alerted Mr. Rotana?s office to a suspected outbreak on January 24.

?We brought three ducks to the Health Ministry for examination and found that it was a case of H5N1,? he said on Wednesday, adding that officials suspected wildlife from a nearby pond had infected the birds.

?We had to destroy more than 300 birds. Now we are observing to make sure it doesn?t spread to other villages or farms,? he said.
