The Price of Cheap Chicken


by Wendy Orent, Los Angeles Times



Chicken has never been cheaper. A whole one can be bought for little more than the price of a Starbucks cup of coffee. But the industrial farming methods that make ever-cheaper chicken possible may also have created the lethal strain of bird flu virus, H5N1, that threatens to set off a global pandemic.

According to Earl Brown, a University of Ottawa flu virologist, lethal bird flu is entirely man-made, first evolving in commercially produced poultry in Italy in 1878. The highly pathogenic H5N1 is descended from a strain that first appeared in Scotland in 1959.

People have been living with backyard flocks of poultry since the dawn of civilization. But it wasn't until poultry production became modernized, and birds were raised in much larger numbers and concentrations, that a virulent bird flu evolved. When birds are packed close together, any brakes on virulence are off. Birds struck with a fatal illness can still easily pass the disease to others, through direct contact or through fecal matter, and lethal strains can evolve. Somehow, the virus that arose in Scotland found its way to China, where, as H5N1, it has been raging for more than a decade.
