Currently, none of the birds and eggs have tested positive for the virus; the quarantine is being taken as a precaution until the results are returned from the lab.
The US Department of Agriculture website explains,
The United States has the strongest AI surveillance program in the world. As part of the existing USDA avian influenza response plans, Federal and State partners as well as industry are responding quickly and decisively to these outbreaks by following these five basic steps: 1) Quarantine – restricting movement of poultry and poultry-moving equipment into and out of the control area; 2) Eradicate – humanely euthanizing the affected flock(s); 3) Monitor region – testing wild and domestic birds in a broad area around the quarantine area; 4) Disinfect – kills the virus in the affected flock locations; and 5) Test – confirming that the poultry farm is AI virus-free. USDA also is working with its partners to actively look and test for the disease in commercial poultry operations, live bird markets and in migratory wild bird populations.
“Bird enthusiasts and breeders who are shopping on the internet need to take care when ordering,” said Dr. Perry Durham, State Veterinarian. “These birds and eggs came from a state where Avian Influenza is rampant, responsible for the loss of millions of turkeys and hens. If you are importing birds or eggs into the state, check the list of states (attached) with Avian Influenza and do not bring birds or eggs from them to protect your flock and others.”
"Avian Influenza is a highly contagious viral disease of chickens, turkeys, pheasants, ducks, quail, geese and many wild birds," states the ADA press release. "Direct contact with infected birds, contaminated objects/equipment, and droplets in the air (short distances) can spread the virus."
The ADA urges all bird owners, whether commercial producers or backyard flock owners, to continue to practice good biosecurity, preventing contact between their birds and wild birds. The Department has resources on its website to help.
All Arizona bird owners can do their part to protect local poultry by immediately reporting sick birds or unusual bird deaths to the Arizona State Veterinarian’s Office at (602) 542-4293 or the USDA sick bird hotline at 1-866-536-7593.
