2024 Avian Influenza Summit to address virus’ impacts on global health beyond poultry

FAYETTEVILLE, Ark. — While surges in colds, flu and even COVID may come and go, agricultural producers are always on the lookout for avian influenza — and not just in poultry flocks. In 2024, highly pathogenic avian influenza has been detected not only in birds, but cattle, swine and humans as well.

To address the current state of HPAI, the University of Arkansas System Division of Agriculture’s Center of Excellence for Poultry Science will host the International Avian Influenza and One Health Emerging Issues Summit on Sept. 30 – Oct. 3 at the Don Tyson Center for Agricultural Sciences in Fayetteville, Arkansas.

While the general public may be most familiar with the H5N1 strain of HPAI, multiple viruses have infected tens of millions of birds and more than 20 species of mammals worldwide since 2022. In response, event organizers have expanded the scope of this year’s annual summit to address emerging issues affecting cattle, swine, bees, humans and more as part of the “One Health” concept.

This year’s summit will feature 55 speakers over four days, more than doubling the number of speakers at the 2023 two-day conference. More than 1,800 individuals from 81 countries registered for the 2023 summit.

In-person attendance is limited to 200 people and online attendance is limited to 1,000 participants this year. There is no cost to attend either way, but registration is required.

Avian influenza, USDA-APHIS response topic of NALC’s July 17 webinar

FAYETTEVILLE, Ark. — In the more than two years since the current outbreak began, highly pathogenic avian influenza, or HPAI, has proven to be a highly adaptable foe, infecting not only poultry, but also dairy cattle and their human handlers.

According to the U.S. Department of Agriculture's Animal and Plant Health Inspection Service, or USDA-APHIS, 97.26 million birds in commercial and backyard flocks, as well as 137 dairy cattle herds, have been affected since the current outbreak’s start in February 2022. In a June 2024 technical report, the CDC reported that the virus has also infected three farm workers in Texas and Michigan this year.

Since December 2023, the number of states where HPAI has been detected has risen from 27 to 48. Since May 24, 2024, 6.41 million birds have been affected, according to USDA-APHIS.

Brook Duer, staff attorney at Penn State Center for Agricultural and Shale Law, said that HPAI remains as virulent and easily transmissible in poultry as when the industry first experienced an outbreak in 2015.

“We are in uncharted territory with HPAI in poultry — it is by far the largest animal disease event in U.S. history,” Duer said. “HPAI may already be a permanent backdrop to poultry and egg production.”

The foundational statutes, regulations, manuals and procedures that give USDA-APHIS its authority will be examined through the lens of HPAI outbreaks in poultry and cattle during the NALC’s next webinar, “HPAI in Poultry and Cattle: How Can We Miss You If You Won’t Go Away?” The webinar will be presented by Duer.

The spillover to dairy cattle has brought more insights and questions. Each host species’ unique response to the virus is vastly different and the virus can mutate quickly, Duer said.

“With dairy cattle, the disease can go nearly undetected through traditional observation of symptoms. This allows it to reach a point in the food production supply chain where pasteurization becomes the primary tool. That might be seen as uncomfortably close to the consumer,” Duer said. “Understanding how USDA-APHIS’ response has progressed to date, and why, will allow producers to better anticipate what research still needs to be done to get the answers producers want.”

The webinar will be held Wednesday, July 17 at 11 a.m. Central/Noon Eastern. Registration is no cost and available online.

HPAI is not only a threat to animals, but also to humans. On June 5, 2024, a 59-year-old man from Mexico City became the first person to die from HPAI. The man did have prior health complications and the source of exposure is unknown, according to Reuters.

Duer said much more still needs to be known about transmission and impact in humans. More extensive, and potentially expensive, detection methods may become routine and legally required at earlier stages.

“With the outbreak of HPAI in dairy cattle and cases of human illness, this topic is extremely important to agricultural producers,” NALC Director Harrison Pittman said. “Brook will give producers a greater understanding of where things are at with HPAI, what USDA-APHIS is doing to resolve the situation and what producers should know about the disease.”

Cooperative Extension Service offering two avian influenza webinars in December

LITTLE ROCK — As one of the nation’s leading poultry-producing states, Arkansas has a keen interest in reducing the spread of the Highly Pathogenic Avian Influenza, often referred to as HPAI. To support that effort, the Cooperative Extension Service — the outreach and education arm of the University of Arkansas System Division of Agriculture — is hosting two HPAI webinar workshops in December.

The first workshop, scheduled for Dec. 5, is for commercial industry producers. The second, scheduled for Dec. 12, is aimed at small and backyard hobby flock owners. Both webinars are scheduled for 6 p.m. (CDT).

Dustan Clark, extension poultry health veterinarian for the Division of Agriculture, will lead both webinars.

There is no charge to participate, but registration is required.

As of Nov. 30, there are confirmed cases of the H5N1 avian influenza in 47 states, including Arkansas, according to the U.S. Department of Agriculture. The most recent detection in Arkansas was Nov. 29, in a commercial broiler production flock in Carroll County.

Avian influenza confirmed at Madison County poultry farm

by Talk Business & Politics staff (staff2@talkbusiness.net)

The Arkansas Department of Agriculture confirmed Friday (Oct. 7) a case of avian influenza on an Arkansas poultry farm in Madison County.

Also known as H5N1 avian influenza (HPAI), avian influenza is an airborne respiratory virus that spreads easily among chickens through nasal and eye secretions, as well as manure. The virus can be spread in various ways from flock to flock, including by wild birds, through contact with infected poultry, by equipment, and on the clothing and shoes of caretakers.

There is no public health concern, experts say, and avian influenza does not affect poultry meat or egg products, which remain safe to eat. The disease is highly pathogenic and can spread quickly among poultry flocks resulting in high mortality rates among birds.

Influenza could threaten state’s poultry industry

by George Jared (gjared@talkbusiness.net)

Disease, especially avian influenza, could impact Arkansas poultry producers in 2022.

The Arkansas Department of Agriculture is urging poultry owners to increase biosecurity measures on their operations in response to several reports of highly pathogenic avian influenza (HPAI) in other states to include some in the Mississippi Flyway.

HPAI is caused by an influenza type A virus which can infect poultry and wild birds. HPAI virus strains are extremely infectious, often fatal to chickens, and can spread rapidly from flock to flock. Symptoms can include sudden increase in bird deaths with no clinical signs, lack of energy and appetite, decrease in egg production, soft- or thin-shelled or misshapen eggs, and more.
