The deadly H5N1 stain of bird flu has been confirmed at a home in the Pakistani capital, the third such case in about a week. But the virus has not affected any one in the country, an official said Saturday.

The virus, which badly affected Pakistan´s poultry industry last year, was found earlier this week in a chicken flock and peacocks at a home in Islamabad, said Mohammed Afzal, spokesman for Ministry of Food, Agriculture and Livestock statement.

"Laboratory tests conducted on samples from one home in Islamabad confirmed the birds had been infected," he said.

However, Afzal said people should not be panicked about the detection of virus merely at one home, as it had not spread to commercial farms, and that poultry eggs and meat were still safe to eat.

Last year, authorities had slaughtered thousands of birds after samples from the poultry farms tested positive for the avian influenza.

There has been no reports of the disease among humans in Pakistan, Afzal said.
