Birds at a Pinal County commercial poultry farm have tested positive for avian influenza, prompting state agencies to quarantine the farm.

The Arizona Department of Health Services and Arizona Department of Agriculture announced the move Friday afternoon. Officials said in a press release the birds began showing signs of avian influenza, or bird flu, on Nov. 11 and it was diagnosed through the Arizona Veterinary Diagnostic Lab and the National Veterinary Services Laboratory.

Both agencies said they believe the risk to the general public is low and that eggs produced after the onset of illness have not entered the food supply, according to the press release.

The name of the farm was not released by the agencies.

Avian influenza is widespread among wild birds, but in recent months has spread to poultry operations and dairy cows in the U.S., according to the Centers for Disease Control and prevention.

CDC says risk to the public is low, but it could impact egg prices as outbreaks have seen the culling of entire flocks of egg-laying operations. A two-year outbreak that has seen the killing of millions of birds has been the primary cultprit for the rise in egg prices around the U.S.

"ADHS is collaborating with AZDA in the response to avian influenza and will continue to monitor influenza activity in Arizona in collaboration with local health departments. While the risk to the general public remains low, workers and individuals that may be at risk for exposure to avian influenza should follow pulbic health guidance," said Nicole Witt, ADHS assistant director for preparedness.
