Greg Herbruck knew 6.5 million of his birds wanted to die, and quick.
But the CEO of Herbruck’s Poultry Ranch wasn’t positive how the household egg producer (one of many largest within the U.S., in enterprise for over three generations) was going to get by means of it, financially or emotionally. One staffer broke down in Herbruck’s workplace in tears.
“The mental toll on our team of dealing with that many dead chickens is just, I mean, you can’t imagine it,” Herbruck mentioned. “I didn’t sleep. Our team didn’t sleep.”
The stress of watching tens of hundreds of sick birds die of avian flu every day, whereas thousands and thousands of others waited to be euthanized, saved everybody awake.
In April 2024, as his first hens examined constructive for the extremely pathogenic avian influenza H5N1 virus, Herbruck turned to the tried-and-true U.S. Department of Agriculture playbook, the “stamping-out” strategy that helped finish the 2014-15 chicken flu outbreak, which was the most important within the U.S. till now.
Within 24 to 48 hours of the primary detection of the virus, state and federal animal well being officers work with farms to cull contaminated flocks to cut back the danger of transmission. That’s adopted by intensive disinfection and months of surveillance and testing to ensure the virus isn’t nonetheless lurking someplace on-site.
Since then, egg farms have needed to make investments thousands and thousands of {dollars} into biosecurity. For occasion, staff bathe in and bathe out, earlier than they begin working and after their shifts finish, to forestall spreading any virus. But their efforts haven’t been sufficient to include the outbreak that began three years in the past.
This time, the danger to human well being is barely rising, specialists say. Sixty-six of the 67 whole human instances within the United States have been simply since March, together with the nation’s first human death, reported final month.
“The last six months have accelerated my concern, which was already high,” mentioned Nahid Bhadelia, an infectious illnesses doctor and the founding director of Boston University’s Center on Emerging Infectious Diseases.
Controlling this virus has change into more difficult, exactly as a result of it’s so entrenched within the world surroundings, spilling into mammals reminiscent of dairy cows, and affecting roughly 150 million birds in industrial and yard flocks within the U.S.
Because laying hens are so inclined to the H5N1 virus, which might wipe out whole flocks inside days of the primary an infection, egg producers have been on the entrance strains within the battle towards varied chicken flu strains for years. But this second feels completely different. Egg producers and the American Egg Board, an business group, are begging for a brand new prevention technique.
Many infectious illness specialists agree that the dangers to human well being of constant present protocols are unsustainable, due to the pressure of chicken flu driving this outbreak.
“The one we’re battling today is unique,” mentioned David Swayne, former director of the Southeast Poultry Research Laboratory on the USDA’s Agricultural Research Service and a number one nationwide knowledgeable in avian influenza.
“It’s not saying for sure there’s gonna be a pandemic” of H5N1, Swayne mentioned, “but it’s saying the more human infections, the spreading into multiple mammal species is concerning.”

For Herbruck, it looks like struggle. Ten months after Herbruck’s Poultry Ranch was hit, the corporate remains to be rebuilding its flocks and rehired many of the 400 employees it laid off.
Still, he and his counterparts within the business stay in worry, watching different farms get hit two, even 3 times prior to now few years.
“I call this virus a terrorist,” he mentioned. “And we are in a battle and losing, at the moment.”
When Biosecurity Isn’t Working … or Just Isn’t Happening
So far, not one of the 23 individuals who contracted the illness from industrial poultry have skilled extreme instances, however the dangers are nonetheless very actual. The first human demise was a Louisiana affected person who had contact with each wild birds and yard poultry. The particular person was over age 65 and reportedly had underlying medical circumstances.
And the official message to each yard farm fans and mega-farms has been broadly the identical: Biosecurity is your greatest weapon towards the unfold of illness.
But there’s a variety of opinions amongst yard flock homeowners about how significantly to take chicken flu, mentioned Katie Ockert, a Michigan State University Extension educator who focuses on biosecurity communications.
Skeptics suppose that “we’re making a mountain out of a molehill,” Ockert mentioned, or that “the media is maybe blowing it out of proportion.” This means there are two varieties of yard poultry fans, Ockert mentioned: these doing nice biosecurity, and people who aren’t even making an attempt.
“I see both,” she mentioned. “I don’t feel like there’s really any middle ground there for people.”
And the challenges of biosecurity are utterly completely different for yard coops than large industrial barns: How are hobbyists with restricted time and budgets purported to create impenetrable fortresses for his or her flocks, when any standing water or timber on the property may draw wild birds carrying the virus?

Rosemary Reams, an 82-year-old retired educator in Ionia, Michigan, grew up farming and has been serving to the native 4-H poultry program for years, educating children the way to increase poultry. Now, with the chicken flu outbreak, “I just don’t let people go out to my barn,” she mentioned.
Reams even swapped actual birds with fake ones for teenagers to make use of whereas being assessed by judges at latest 4-H competitions, she mentioned.
“We made changes to the fair last year, which I got questioned about a lot. And I said, ‘No, I gotta think about the safety of the kids.’”
Reams was shocked by the information of the demise of the Louisiana yard flock proprietor. She even has questioned whether or not she ought to proceed to maintain her personal flock of 20 to 30 chickens and a pair of turkeys.
“But I love ’em. At my age, I need to be doing it. I need to be outside,” Reams mentioned. “That’s what life is about.” She mentioned she’ll do her greatest to guard herself and her 4-H children from chicken flu.
Even “the best biosecurity in the world” hasn’t been sufficient to save lots of giant industrial farms from an infection, mentioned Emily Metz, president and CEO of the American Egg Board.
The egg business thought it realized the way to outsmart this virus after the 2014-15 outbreak. Back then, “we were spreading it amongst ourselves between egg farms, with people, with trucks,” Metz mentioned. So egg producers went into lockdown, she mentioned, creating intensive biosecurity measures to attempt to block the routes of transmission from wild birds or different farms.
Metz mentioned the measures egg producers are taking now are intensive.
“They have invested hundreds of millions of dollars in improvements, everything from truck washing stations — which is washing every truck from the FedEx man to the feed truck — and everything in between: busing in workers so that there’s less foot traffic, laser light systems to prevent waterfowl from landing.”
Lateral unfold, when the virus is transmitted from farm to farm, has dropped dramatically, down from 70% of instances within the final outbreak to simply 15% as of April 2023, according to the USDA.
And but, Metz mentioned, “all the measures we’re doing are still getting beat by this virus.”

The Fight Over Vaccinating Birds
Perhaps probably the most contentious debate about chicken flu within the poultry business proper now’s whether or not to vaccinate flocks.
Given the mounting demise toll for animals and the growing danger to people, there’s a rising push to vaccinate sure poultry towards avian influenza, which international locations like China, Egypt, and France are already doing.
In 2023, the World Organization for Animal Health urged nations to think about vaccination “as part of a broader disease prevention and control strategy.”
Swayne, the avian influenza knowledgeable and poultry veterinarian, works with WOAH and mentioned most of his colleagues within the animal and public well being world “see vaccination of poultry as a positive tool in controlling this panzootic in animals,” but in addition as a instrument that reduces possibilities for human an infection, and possibilities for extra mutations of the virus to change into extra human-adapted.
But vaccination may put poultry meat exporters (whose birds are genetically much less inclined to H5N1 than laying hens) prone to shedding billions of {dollars} in worldwide commerce offers. That’s due to considerations that vaccination, which lowers the severity of illness in poultry, may masks infections and produce the virus throughout borders, in keeping with John Clifford, a former chief veterinary officer of the USDA. Clifford is at present an adviser to the USA Poultry and Egg Export Council.
“If we vaccinate, we not only lose $6 billion potentially in exports a year,” Clifford mentioned. “If they shut us off, that product comes back on the U.S. market. Our economists looked at this and said we would lose $18 billion domestically.”
Clifford added that might additionally imply the lack of “over 200,000 agricultural jobs.”
Even if these commerce guidelines modified to permit meat and eggs to be harvested from vaccinated birds, logistical hurdles stay.
“Vaccination possibly could be on the horizon in the future, but it’s not going to be tomorrow or the next day, next year, or whatever,” Clifford mentioned.
Considering only one impediment: No present HPAI vaccine is an ideal match for the present pressure, in keeping with the USDA. But if the virus evolves to have the ability to transmit effectively from human to human, he mentioned, “that would be a game changer for everybody, which would probably force vaccination.”
Last month, the USDA announced it might “pursue a stockpile that matches current outbreak strains” in poultry.
“While deploying a vaccine for poultry would be difficult in practice and may have trade implications, in addition to uncertainty about its effectiveness, USDA has continued to support research and development in avian vaccines,” the company mentioned.
At this level, Metz argued, the business can’t afford to not strive vaccination, which has helped eradicate illnesses in poultry earlier than.
“We’re desperate, and we need every possible tool,” she mentioned. “And right now, we’re fighting this virus with at least one, if not two, arms tied behind our back. And the vaccine can be a huge hammer in our toolbox.”
But until the federal authorities acts, that instrument received’t be used.
Industry considerations apart, infectious illnesses doctor Bhadelia mentioned there’s an pressing must give attention to lowering the danger to people of getting contaminated within the first place. And meaning lowering “chances of infections in animals that are around humans, which include cows and chickens. Which is why I think vaccination to me sounds like a great plan.”
The lesson “that we keep learning every single time is that if we’d acted earlier, it would have been a smaller problem,” she mentioned.
