Benin minister confirms bird flu in two locations


COTONOU (AFP) - The west African country of Benin Saturday confirmed bird flu outbreaks at two suspect southern sites, where more than 240 chickens were culled and burnt this week.

Agriculture Minister Roger Dovonou said samples from birds had been sent to the World Organization for Animal Health laboratory in Padua, in Italy which had confirmed that they were infected with the deadly H5N1 strain of the virus.

The ministry had reported the country's first suspected cases of bird flu on December 7 in the commercial capital Cotonou and in Adjara, both located in southern coastal tip.

Vets then slaughtered and incinerated 242 chickens and disinfected the two sites, which were cordoned off.

Benin launched bird flu prevention measures in 2005, including banning poultry imports from countries hit by H5N1.

The virus has been reported in several countries in Benin's immediate vicinity, with one person having died from bird flu in neighbouring Nigeria.

Separately, Pakistan reported its first bird-flu related death in a human Saturday and the World Health Organisation reported Myanmar's first human case of the virus.
