PHOENIX – The Arizona Department of Agriculture quarantined birds and eggs brought into the state from a facility in Iowa after birds at the facility tested positive for H5 avian influenza.

Four properties where the 13 quail and chickens and about 40 quail and partridge eggs were shipped are under quarantine, the agency reported. The properties are in Pinal, Mohave, Santa Cruz and Yavapai counties. Department officials the birds are undergoing tests for the virus.

“Bird enthusiasts and breeders who are shopping on the Internet need to take care when ordering,” State Veterinarian Dr. Perry Durham said. “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 with avian influenza and do not bring birds or eggs from them to protect your flock and others.”

The Iowa facility shipped birds and eggs to nearly 75 percent of the United States weeks before the initial testing, the agency reported.
