NEW YORK In an effort to head off an epidemic of dangerous bird flu, chicken farmers in the United States will immediately begin testing nearly all flocks for influenza, an industry trade group has announced.
The National Chicken Council said Thursday that poultry-processing companies that control about 90 percent of the country's chicken production had joined the program. By Jan. 16, they are to start testing about 1.6 million birds a year, a council spokesman said.
A poultry expert, Carol Cardona, said the decision "makes perfect scientific sense" in that it creates a system for spotting mutating influenza strains and could help avert panics over routine types of flu that affect birds.
However, Cardona said, the surveillance program might not speed up farmers' ability to spot the dangerous H5N1 flu strain, which has killed millions of chickens in Asia and 76 humans.
The H5N1 strain is so lethal that if it reaches America, it is likely to be detected quickly because it will probably kill the entire first flock it infects. "There's no producer on this planet that's going to accept 100 percent mortality without notifying someone," said Cardona, a poultry veterinarian at the University of California, Davis.
At the U.S. Department of Agriculture, the chief of the Animal and Plant Health Inspection Service, W. Ron DeHaven, agreed that "any blip in bird mortality" would alert poultry farmers that the H5N1 strain had arrived. But DeHaven added that "any surveillance in avian influenza is a good thing."
The chicken industry's program is stricter than his department's voluntary one, he said.
Flu is common in birds, and most types produce only respiratory symptoms, leaving the birds safe to eat once they recover. Lethal strains are already legally "notifiable" diseases, meaning that a farmer or a veterinarian who finds them in a flock must notify state veterinarians, who must in turn notify the Agriculture Department.
"But we're not waiting for signs to show up," said Richard Lobb, a council spokesman. Under the program, chicken farmers, most of whom raise flocks under contract with major processors like Tyson's Foods or Pilgrim's Pride, will take swabs or beak samples from 11 chickens in each healthy flock. Any suspicious results found in local labs will be sent on to an Agriculture Department laboratory in Ames, Iowa, for confirmation, Lobb said.
Because a flock of broilers goes from hatchlings to slaughter in as little as seven weeks, the industry produces about 150,000 flocks a year, Lobb said. Each will be tested about two weeks before slaughter.
If any H5 or H7 strains of virus are found, the flock will be destroyed on the farm, he said, and nearby flocks will be tested.
There is no H5N1 flu in the Western Hemisphere now, according to health authorities. The most likely possible sources of introduction are thought to be birds smuggled in for the pet trade or for cockfighting, or migratory birds.
, particularly ducks and geese that mingle in the Arctic nesting grounds with birds from Asia and then fly southward along the Pacific Coast in the spring. (However, if the flu mutates into a strain that passes easily between humans, the most likely introduction source will be an airline jet passenger, doctors say.)
