HPAI is a deadly disease for poultry. It can infect poultry such as chickens, turkeys, pheasants, quail, domestic ducks, geese, and guinea fowl and wild birds, including waterfowl, raptors, and corvids. HPAI is extremely infectious and can spread easily and rapidly from bird to bird and flock to flock. According to the U.S. Centers for Disease Control and Prevention, this strain of HPAI is not known to present a public health concern.
All those involved in poultry production to take extra steps to prevent their flocks from becoming infected. All poultry producers, from small backyard hobby producers to large commercial operations, should take precautions to protect their birds and review their biosecurity plans. Biosecurity refers to everything you can do to keep diseases – and the viruses, bacteria, funguses, parasites, and other microorganisms that cause disease – away from birds, property, and people. Some best practices are listed below; find more at: Tips on Protecting Your Birds.
Best practices include:
Birds affected with HPAI may show one or more of the following clinical signs: sudden death without clinical signs; lack of energy and appetite; decreased egg production; soft-shelled or misshapen eggs; swelling of the head, eyelids, comb, wattles, and hocks; purple discoloration of the wattles, combs, and legs; nasal discharge; coughing, sneezing; lack of coordination; and diarrhea. The Highly Pathogenic strain can spread and kill an entire flock within days, backyard flocks included. Many, if not all, of the birds in a flock will be affected.
To report sick birds, unexplained high number of deaths, or sudden drop in egg production, please contact AGM’s Division of Animal Industry at (518) 457-3502 or the USDA at (866) 536-7593.
Unusual illness and deaths of wild birds can be reported to the New York Department of Environmental Conservation, (631) 444-0310.

National Poultry Improvement Plan , NPIP is a voluntary State–Federal cooperative testing and certification program for poultry breeding flocks, baby chicks, poults, hatching eggs, hatcheries, and dealers. This program tests against poultry diseases including HPAI.Participating hatcheries also have biosecurity measures in place to help mitigate the risk of disease on their farms, which means a lower risk to you if you’re buying chicks. If you aren’t sure if the hatchery you source from is NPIP certified, you can use this NPIP Participants States page to search for them (the map is clickable).
