Laramie, WY – U-S department of agriculture secretary Mike Johanns says poultry producers should watch their flocks for signs of avian or bird flu. The virus has not yet been detected in the United States although state and federal officials are vigilant. But Johanns says that even one bird suspected of carrying the high path or more dangerous variant of avian flu would probably require destroying the entire flock. However, the USDA chief says he has easy access to federal funds to pay farmers for losses. Wyoming's poultry industry is small compared to national standards, but a recent USDA report shows that broilers accounted for more than half a million dollars in state agricultural production.
