Officials say quarantines were ordered for four properties in Arizona that had quail, chickens and eggs that came from an Iowa facility where other birds tested positive for a bird flu virus.
The Arizona Department of Health Services said the properties are located in Pinal, Mohave, Santa Cruz and Yavapai counties.
It's unknown whether the birds in Arizona have contracted the virus.
They will be tested for the virus. It could take as long as six days to get the test results.
Health officials urge people who bring birds into Arizona to first check the list of 15 states where avian influenza has been detected.
Bird owners are asked to immediately report sick birds or unusual bird deaths to the state veterinarian's office.
