Cambodia Thursday confirmed two more bird flu cases at a zoo and a small family farm after swans and herons died.

"Samples were tested positive for H5N1 at a Paris laboratory," said San Vanthy, the spokesman for the ministries of agriculture and health.

The government has temporarily closed the Phnom Tamao Zoo, about 50 km south of the capital, to prevent the spread of virus to humans.

Cambodia's first bird flu case was found two weeks ago in a chicken farm near the capital Phnom Penh where more than 3,000 chickens were died.

Cambodia has banned the importation of birds and bird products from countries that have reported cases of bird flu, and measures have been taken to closely monitor domestic poultry stocks and farms.

The UN Food and Agriculture Organization pledged about 380,000 US dollars to assist Cambodia in fighting the disease. Meanwhile, the World Health Organization is supplying two technical experts to help fight the disease. They are expected to arrive here from France on Friday.

However, no person has become infected with bird flu in Cambodia so far.
