Greg Herbruck knew 6.5 million of his birds wanted to die, and quick.
However 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 it, financially or emotionally. One staffer broke down in Herbruck’s workplace in tears.
“The psychological toll on our workforce of coping with that many lifeless chickens is simply, I imply, you possibly can’t think about it,” Herbruck mentioned. “I didn’t sleep. Our workforce didn’t sleep.”

The stress of watching tens of hundreds of sick birds die of avian flu every day, whereas tens of millions of others waited to be euthanized, stored everybody awake.
In April 2024, as his first hens examined optimistic for the extremely pathogenic avian influenza H5N1 virus, Herbruck turned to the tried-and-true U.S. Division of Agriculture playbook, the “stamping-out” technique that helped finish the 2014-15 hen flu outbreak, which was the most important within the U.S. till now.
Inside 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 in depth 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 tens of millions of {dollars} into biosecurity. For example, staff bathe in and bathe out, earlier than they begin working and after their shifts finish, to stop spreading any virus. However their efforts haven’t been sufficient to comprise the outbreak that began three years in the past.
This time, the danger to human well being is just rising, consultants say. Sixty-six of the 67 complete human circumstances in america have been simply since March, together with the nation’s first human dying, reported final month.
“The final six months have accelerated my concern, which was already excessive,” mentioned Nahid Bhadelia, an infectious illnesses doctor and the founding director of Boston College’s Heart on Rising Infectious Ailments.
Controlling this virus has turn into more difficult, exactly as a result of it’s so entrenched within the international atmosphere, spilling into mammals equivalent to dairy cows, and affecting roughly 150 million birds in business and yard flocks within the U.S.
As a result of laying hens are so vulnerable to the H5N1 virus, which may wipe out complete flocks inside days of the primary an infection, egg producers have been on the entrance traces within the combat towards numerous hen flu strains for years. However this second feels totally different. Egg producers and the American Egg Board, an business group, are begging for a brand new prevention technique.
Many infectious illness consultants agree that the dangers to human well being of continuous present protocols are unsustainable, due to the pressure of hen flu driving this outbreak.
“The one we’re battling right now is exclusive,” mentioned David Swayne, former director of the Southeast Poultry Analysis Laboratory on the USDA’s Agricultural Analysis Service and a number one nationwide professional in avian influenza.
“It’s not saying for positive there’s gonna be a pandemic” of H5N1, Swayne mentioned, “however it’s saying the extra human infections, the spreading into a number of mammal species is regarding.”
For Herbruck, it looks like struggle. Ten months after Herbruck’s Poultry Ranch was hit, the corporate continues to be rebuilding its flocks and rehired many of the 400 staff it laid off.
Nonetheless, he and his counterparts within the business stay in worry, watching different farms get hit two, even thrice up to now few years.
“I name this virus a terrorist,” he mentioned. “And we’re in a battle and dropping, in the mean time.”
When Biosecurity Isn’t Working … or Simply Isn’t Taking place
To this point, not one of the 23 individuals who contracted the illness from business poultry have skilled extreme circumstances, however the dangers are nonetheless very actual. The primary human dying was a Louisiana affected person who had contact with each wild birds and yard poultry. The individual was over age 65 and reportedly had underlying medical circumstances.
And the official message to each yard farm lovers and mega-farms has been broadly the identical: Biosecurity is your greatest weapon towards the unfold of illness.
However there’s a spread of opinions amongst yard flock house owners about how severely to take hen flu, mentioned Katie Ockert, a Michigan State College Extension educator who focuses on biosecurity communications.
Skeptics assume that “we’re making a mountain out of a molehill,” Ockert mentioned, or that “the media is perhaps blowing it out of proportion.” This implies there are two sorts of yard poultry lovers, Ockert mentioned: these doing nice biosecurity, and people who aren’t even making an attempt.
“I see each,” she mentioned. “I don’t really feel like there’s actually any center floor there for folks.”
And the challenges of biosecurity are utterly totally different for yard coops than huge business barns: How are hobbyists with restricted time and budgets alleged to create impenetrable fortresses for his or her flocks, when any standing water or bushes 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, instructing youngsters methods to elevate poultry. Now, with the hen flu outbreak, “I simply don’t let folks exit to my barn,” she mentioned.
Reams even swapped actual birds with pretend ones for youths to make use of whereas being assessed by judges at current 4-H competitions, she mentioned.
“We made adjustments to the honest final yr, which I bought questioned about lots. And I mentioned, ‘No, I gotta take into consideration the security of the children.’”
Reams was shocked by the information of the dying 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.
“However I really like ’em. At my age, I must be doing it. I must be exterior,” Reams mentioned. “That’s what life is about.” She mentioned she’ll do her greatest to guard herself and her 4-H youngsters from hen flu.
Even “one of the best biosecurity on this planet” hasn’t been sufficient to avoid wasting giant business farms from an infection, mentioned Emily Metz, president and CEO of the American Egg Board.
The egg business thought it realized methods to outsmart this virus after the 2014-15 outbreak. Again then, “we have been spreading it amongst ourselves between egg farms, with folks, with vehicles,” 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 in depth.
“They’ve invested tons of of tens of millions of {dollars} in enhancements, every thing from truck washing stations — which is washing each truck from the FedEx man to the feed truck — and every thing in between: busing in staff in order that there’s much less foot visitors, laser mild techniques to stop waterfowl from touchdown.”
Lateral unfold, when the virus is transmitted from farm to farm, has dropped dramatically, down from 70% of circumstances within the final outbreak to simply 15% as of April 2023, in keeping with the USDA.
And but, Metz mentioned, “all of the measures we’re doing are nonetheless getting beat by this virus.”
The Battle Over Vaccinating Birds
Maybe probably the most contentious debate about hen flu within the poultry business proper now could be whether or not to vaccinate flocks.
Given the mounting dying toll for animals and the rising 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 Group for Animal Well being urged nations to think about vaccination “as a part of a broader illness prevention and management technique.”
Swayne, the avian influenza professional 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 optimistic software in controlling this panzootic in animals,” but additionally as a software that reduces probabilities for human an infection, and probabilities for added mutations of the virus to turn into extra human-adapted.
However vaccination may put poultry meat exporters (whose birds are genetically much less vulnerable to H5N1 than laying hens) vulnerable to dropping 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 presently an adviser to the USA Poultry and Egg Export Council.
“If we vaccinate, we not solely lose $6 billion doubtlessly in exports a yr,” Clifford mentioned. “In the event that they shut us off, that product comes again on the U.S. market. Our economists checked out this and mentioned we might lose $18 billion domestically.”
Clifford added that might additionally imply the lack of “over 200,000 agricultural jobs.”
Even when these commerce guidelines modified to permit meat and eggs to be harvested from vaccinated birds, logistical hurdles stay.
“Vaccination presumably may very well be on the horizon sooner or later, however it’s not going to be tomorrow or the following day, subsequent yr, or no matter,” Clifford mentioned.
Contemplating only one impediment: No present HPAI vaccine is an ideal match for the present pressure, in keeping with the USDA. But when the virus evolves to have the ability to transmit effectively from human to human, he mentioned, “that might be a recreation changer for everyone, which might in all probability power vaccination.”
Final month, the USDA introduced it could “pursue a stockpile that matches present outbreak strains” in poultry.
“Whereas deploying a vaccine for poultry could be troublesome in observe and will have commerce implications, along with uncertainty about its effectiveness, USDA has continued to assist analysis and growth in avian vaccines,” the company mentioned.
At this level, Metz argued, the business can’t afford to not attempt vaccination, which has helped eradicate illnesses in poultry earlier than.
“We’re determined, and we want each potential software,” she mentioned. “And proper now, we’re combating this virus with at the least one, if not two, arms tied behind our again. And the vaccine is usually a enormous hammer in our toolbox.”
However except the federal authorities acts, that software gained’t be used.
Business considerations apart, infectious illnesses doctor Bhadelia mentioned there’s an pressing must deal with lowering the danger to people of getting contaminated within the first place. And meaning lowering “possibilities of infections in animals which might be round people, which embrace cows and chickens. Which is why I feel vaccination to me feels like a fantastic plan.”
The lesson “that we continue to learn each single time is that if we’d acted earlier, it could have been a smaller downside,” she mentioned.
