WASHINGTON, March 4, 2022 – The United States Department of Agriculture’s (USDA) Animal and Plant Overall health Inspection Support (APHIS) has confirmed the existence of really pathogenic avian influenza (HPAI) in a flock of commercial broiler chickens in Stoddard County, Missouri.

Samples from the flock were being tested at the College of Missouri Veterinary Clinical Diagnostic Laboratory, portion of the Nationwide Animal Wellness Laboratory Network, and confirmed at the APHIS Nationwide Veterinary Providers Laboratories (NVSL) in Ames, Iowa.

APHIS is doing the job carefully with condition animal wellness officers in Missouri on a joint incident reaction. Point out officers quarantined the influenced premises, and birds on the homes will be depopulated to reduce the unfold of the disorder. Birds from the flock will not enter the food stuff process.

According to the U.S. Facilities for Illness Command and Prevention, the recent HPAI detections do not existing an quick general public health concern. No human circumstances of these avian influenza viruses have been detected in the United States. As a reminder, the suitable managing and cooking of poultry and eggs to an inner temperature of 165 ˚F kills microbes and viruses.

As part of present avian influenza reaction strategies, Federal and Condition companions are functioning jointly on extra surveillance and screening in places all around the afflicted flock. The United States has the strongest AI surveillance plan in the entire world, and USDA is performing with its associates to actively glance for the disease in commercial poultry operations, live chicken marketplaces and in migratory wild bird populations.

Anybody involved with poultry manufacturing from the smaller backyard to the substantial business producer need to review their biosecurity routines to assure the health and fitness of their birds. APHIS has products about biosecurity, which includes video clips, checklists, and a toolkit readily available at

USDA will report these findings to the Entire world Organisation for Animal Health (OIE) as well as intercontinental trading companions. USDA also proceeds to converse with buying and selling partners to encourage adherence to OIE standards and minimize trade impacts. OIE trade rules phone on countries to foundation trade restrictions on audio science and, every time feasible, limit limitations to those people animals and animal products inside a outlined region that pose a threat of spreading disorder of concern.

APHIS will continue on to announce the very first circumstance of HPAI in professional and backyard flocks detected in a State but will not announce subsequent detections in the Point out. All situations in business and backyard flocks will be detailed on the APHIS internet site at

In addition to practising good biosecurity, all chicken homeowners should really avoid contact in between their birds and wild birds and report ill birds or unconventional chicken deaths to State/Federal officers, both as a result of their condition veterinarian or by APHIS’ toll-free of charge amount at 1-866-536-7593. APHIS urges producers to look at bringing birds indoors when probable to even more stop exposures. The Animal Wellness Protection Act authorizes APHIS to present indemnity payments to producers for birds and eggs that should be depopulated during a disease reaction. APHIS also delivers payment for disposal activities and virus elimination functions. Supplemental facts on biosecurity for backyard flocks can be uncovered at

Extra qualifications
Avian influenza (AI) is brought on by an influenza kind A virus which can infect poultry (this sort of as chickens, turkeys, pheasants, quail, domestic ducks, geese, and guinea fowl) and is carried by no cost flying waterfowl these types of as ducks, geese and shorebirds. AI viruses are labeled by a combination of two groups of proteins: hemagglutinin or “H” proteins, of which there are 16 (H1–H16), and neuraminidase or “N” proteins, of which there are 9 (N1–N9). Several different combos of “H” and “N” proteins are feasible. Every single combination is considered a distinct subtype and can be further broken down into various strains which flow into within just flyways/geographic regions. AI viruses are more categorised by their pathogenicity (very low or significant)—the capability of a unique virus strain to deliver disease in domestic poultry.



USDA touches the lives of all Us residents every single day in so several good ways. In the Biden-Harris Administration, USDA is transforming America’s food stuff system with a greater concentration on extra resilient nearby and regional foodstuff output, fairer markets for all producers, guaranteeing entry to secure, wholesome and healthy foods in all communities, building new marketplaces and streams of revenue for farmers and producers working with local climate clever food stuff and forestry tactics, producing historic investments in infrastructure and clean up electricity abilities in rural America, and committing to fairness across the Office by eliminating systemic limitations and creating a workforce much more consultant of The united states.
