Manila: The Philippines on Sunday warned citizens not to kill or poach migratory birds that usually fly in from China, the possible source of a virus that triggered the Southeast Asian nation’s first outbreak of avian flu, to avoid worsening the situation.
There has been no case of human transmission but the virus prompted a cull of 200,000 fowl last week after it was detected on a farm in the province of Pampanga, north of the capital Manila, and spread to five neighbouring farms.
Migratory birds or smuggled ducks from China may have brought in the virus, agriculture secretary Emmanuel Pinol has said.
The bird migration season in the Philippines usually starts around September, with the birds returning to their breeding grounds the following March, Mundita Lim, director of the Biodiversity Management Bureau (BMB), said in an advisory.
“The culling, poisoning or chasing of migratory birds is strongly discouraged as they have proven ineffective and counterproductive,” she added.
Sick or dead wild birds should immediately be reported to the Department of Agriculture to allow checks for the virus, Lim said, urging breeders in areas frequented by migratory birds to guard their flocks against contact with them.
Early tests of the virus in the avian flu outbreak ruled out the highly pathogenic H5N1 strain, but Philippine officials have sought further testing by an Australian animal health laboratory that is part of a global network combating the disease.
The Philippines is monitoring the quality and prices of poultry products in its markets, but believes farm authorities have managed to isolate and contain the virus, the presidential palace said in a statement.
Roy Cimatu, the secretary of environment and natural resources, said his department would step up surveillance against efforts to smuggle wild birds by sea and air.
