Highly pathogenic avian influenza detected (HPAI)

Highly Pathogenic Avian Influenza detected (HPAI)

The New York State Department of Environmental Conservation (DEC) announced that the U.S. Department of Agriculture's (USDA) National Veterinary Services Laboratory confirmed an outbreak of Highly Pathogenic Avian Influenza (HPAI) virus affecting the Reynolds Game Farm pheasant population.

DEC began investigating suspicious deaths at the Game Farm, located near Ithaca in Tompkins County, on March 20 and initial test results indicated a possible outbreak of the H5N1 avian influenza (AI) virus. On March 21, the farm was put under quarantine following positive test results from the Cornell Wildlife Health Lab. A full 120-day quarantine period for the farm is required. This week, at least 500 of DEC's breeder flock of 6,600 pheasants died from HPAI.

DEC is working closely with animal health experts at the New York State Department of Agriculture and Markets (AGM) and the USDA National Veterinary Services Laboratory and following standard protocol for an outbreak of HPAI.

Cooperatively managed by DEC, AGM and USDA, the remaining breeder flock of pheasants on the property is being depopulated to prevent the spread of the disease in accordance with standard HPAI response protocols. Birds from the flocks will not enter the food system. As part of existing avian influenza response plans, AGM and USDA are working jointly on additional surveillance and testing in areas around the affected flock. Additional information on the USDA response plan can be found at USDA APHIS | Highly Pathogenic Avian Influenza (HPAI).

The Centers for Disease Control and Prevention states that the recent HPAI detections in birds do not present an immediate public health concern. HPAI cases in humans are rare, and symptoms are typically mild. The risk of a person becoming infected is low.

DEC will continue to work with partners at AGM and USDA in a swift and thorough response to the outbreak.

Raptors and HPAI:

More information about how raptors are affected by this virus was shared by the University of Minnesota on 2/28/22. The link to the webinar recording can be found at: https://mediaspace.umn.edu/media/t/1_n0drrg4i

NPIP (National Poultry Improvement Program):

There are many hatcheries that participate in this program, which tests against poultry diseases, including Avian Influenza. 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 in. 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): http://www.poultryimprovement.org/statesContent.cfm
