Small-scale poultry farming and wild birds are being unfairly blamed for the bird flu crisis now affecting large parts of the world. A new report from GRAIN shows how the transnational poultry industry is the root of the problem and must be the focus of efforts to control the virus.

The spread of industrial poultry production and trade networks has created ideal conditions for the emergence and transmission of lethal viruses like the H5N1 strain of bird flu. Once inside densely populated factory farms, viruses can rapidly become lethal and amplify. Air thick with viral load from infected farms is carried for kilometres, while integrated trade networks spread the disease through many carriers: live birds, day-old-chicks, meat, feathers, hatching eggs, eggs, chicken manure and animal feed.

"Everyone is focused on migratory birds and backyard chickens as the problem," says Devlin Kuyek of GRAIN. "But they are not effective vectors of highly pathogenic bird flu. The virus kills them, but is unlikely to be spread by them."

For example, in Malaysia, the mortality rate from H5N1 among village chicken is only 5%, indicating that the virus has a hard time spreading among small scale chicken flocks. H5N1 outbreaks in Laos, which is surrounded by infected countries, have only occurred in the nation's few factory farms, which are supplied by Thai hatcheries. The only cases of bird flu in backyard poultry, which account for over 90% of Laos' production, occurred next to the factory farms.

"The evidence we see over and over again, from the Netherlands in 2003 to Japan in 2004 to Egypt in 2006, is that lethal bird flu breaks out in large scale industrial chicken farms and then spreads," Kuyek explains.
