Keith Poulsen’s jaw dropped when farmers confirmed him photos on their cellphones on the World Dairy Expo in Wisconsin in October. A livestock veterinarian on the University of Wisconsin, Poulsen had seen sick cows earlier than, with their noses dripping and udders slack.
But the size of the farmers’ efforts to deal with the sick cows shocked him. They confirmed movies of programs they constructed to hydrate tons of of cattle without delay. In 14-hour shifts, dairy staff pumped gallons of electrolyte-rich fluids into ailing cows by steel tubes inserted into the esophagus.
“It was like watching a field hospital on an active battlefront treating hundreds of wounded soldiers,” he stated.
Nearly a yr into the primary outbreak of the chicken flu amongst cattle, the virus exhibits no signal of slowing. The U.S. authorities didn’t remove the virus on dairy farms when it was confined to a handful of states, by rapidly figuring out contaminated cows and taking measures to maintain their infections from spreading. Now no less than 875 herds throughout 16 states have examined optimistic.
Experts say they’ve misplaced religion within the authorities’s capability to include the outbreak.
“We are in a terrible situation and going into a worse situation,” stated Angela Rasmussen, a virologist on the University of Saskatchewan in Canada. “I don’t know if the bird flu will become a pandemic, but if it does, we are screwed.”
To perceive how the chicken flu obtained out of hand, KFF Health News interviewed practically 70 authorities officers, farmers and farmworkers, and researchers with experience in virology, pandemics, veterinary medication, and extra.
Together with emails obtained from native well being departments by public data requests, this investigation revealed key issues, together with deference to the farm trade, eroded public well being budgets, neglect for the security of agriculture staff, and the sluggish tempo of federal interventions.
Case in level: The U.S. Department of Agriculture this month introduced a federal order to check milk nationwide. Researchers welcomed the information however stated it ought to have occurred months in the past — earlier than the virus was so entrenched.
“It’s disheartening to see so many of the same failures that emerged during the covid-19 crisis reemerge,” stated Tom Bollyky, director of the Global Health Program on the Council on Foreign Relations.

Far extra chicken flu harm is inevitable, however the extent of it will likely be left to the Trump administration and Mother Nature. Already, the USDA has funneled greater than $1.7 billion into tamping down the chicken flu on poultry farms since 2022, which incorporates reimbursing farmers who’ve needed to cull their flocks, and greater than $430 million into combating the chicken flu on dairy farms. In coming years, the chicken flu could price billions of {dollars} extra in bills and losses. Dairy trade specialists say the virus kills roughly 2% to five% of contaminated dairy cows and reduces a herd’s milk manufacturing by about 20%.
Worse, the outbreak poses the specter of a pandemic. More than 60 folks within the U.S. have been contaminated, primarily by cows or poultry, however circumstances may skyrocket if the virus evolves to unfold effectively from individual to individual. And the recent news of an individual critically unwell in Louisiana with the chicken flu exhibits that the virus could be harmful.
Just a few mutations may enable the chicken flu to unfold between folks. Because viruses mutate inside human and animal our bodies, every an infection is sort of a pull of a slot machine lever.
“Even if there’s only a 5% chance of a bird flu pandemic happening, we’re talking about a pandemic that probably looks like 2020 or worse,” stated Tom Peacock, a chicken flu researcher on the Pirbright Institute within the United Kingdom, referring to covid. “The U.S. knows the risk but hasn’t done anything to slow this down,” he added.
Beyond the chicken flu, the federal authorities’s dealing with of the outbreak reveals cracks within the U.S. well being safety system that may enable different dangerous new pathogens to take root. “This virus may not be the one that takes off,” stated Maria Van Kerkhove, director of the rising illnesses group on the World Health Organization. “But this is a real fire exercise right now, and it demonstrates what needs to be improved.”
A Slow Start
It could have been a grackle, a goose, or another wild chicken that contaminated a cow in northern Texas. In February, the state’s dairy farmers took be aware when cows stopped making milk. They labored alongside veterinarians to determine why. In lower than two months, veterinary researchers recognized the extremely pathogenic H5N1 chicken flu virus because the offender.
Long listed amongst pathogens with pandemic potential, the chicken flu’s unprecedented unfold amongst cows marked a worrying shift. It had advanced to thrive in animals which can be extra like folks biologically than birds.
After the USDA introduced the dairy outbreak on March 25, management shifted from farmers, veterinarians, and native officers to state and federal businesses. Collaboration disintegrated virtually instantly.
Farmers fearful the federal government would possibly block their milk gross sales and even demand sick cows be killed, as poultry are, stated Kay Russo, a livestock veterinarian in Fort Collins, Colorado.
Instead, Russo and different veterinarians stated, they had been dismayed by inaction. The USDA didn’t reply to their pressing requests to help research on dairy farms — and for cash and confidentiality insurance policies to guard farmers from monetary loss in the event that they agreed to check animals.
The USDA introduced that it could conduct research itself. But researchers grew anxious as weeks handed with out outcomes. “Probably the biggest mistake from the USDA was not involving the boots-on-the-ground veterinarians,” Russo stated.
Will Clement, a USDA senior adviser for communications, stated in an e-mail: “Since first learning of H5N1 in dairy cattle in late March 2024, USDA has worked swiftly and diligently to assess the prevalence of the virus in U.S. dairy herds.” The company supplied analysis funds to state and nationwide animal well being labs starting in April, he added.

The USDA didn’t require lactating cows to be examined earlier than interstate journey till April 29. By then, the outbreak had unfold to eight different states. Farmers typically transfer cattle throughout nice distances, for calving in a single place, elevating in heat, dry climates, and milking in cooler ones. Analyses of the virus’s genes implied that it unfold between cows fairly than repeatedly leaping from birds into herds.
Milking tools was a possible supply of an infection, and there have been hints of different prospects, reminiscent of by the air as cows coughed or in droplets on objects, like work boots. But not sufficient knowledge had been collected to know the way precisely it was taking place. Many farmers declined to check their herds, regardless of an announcement of funds to compensate them for misplaced milk manufacturing in May.
“There is a fear within the dairy farmer community that if they become officially listed as an affected farm, they may lose their milk market,” stated Jamie Jonker, chief science officer on the National Milk Producers Federation, a corporation that represents dairy farmers. To his information, he added, this hasn’t occurred.
Speculation stuffed information gaps. Zach Riley, head of the Colorado Livestock Association, stated he suspected that wild birds could also be spreading the virus to herds throughout the nation, regardless of scientific knowledge suggesting in any other case. Riley stated farmers had been contemplating whether or not to put in “floppy inflatable men you see outside of car dealerships” to keep at bay the birds.
Advisories from agriculture departments to farmers had been considerably speculative, too. Officials advisable biosecurity measures reminiscent of disinfecting tools and limiting guests. As the virus saved spreading all through the summer time, USDA senior official Eric Deeble stated at a press briefing, “The response is adequate.”
The USDA, the Centers for Disease Control and Prevention, and the Food and Drug Administration introduced a united entrance at these briefings, calling it a “One Health” method. In actuality, agriculture businesses took the lead.
This was express in an e-mail from an area well being division in Colorado to the county’s commissioners. “The State is treating this primarily as an agriculture issue (rightly so) and the public health part is secondary,” wrote Jason Chessher, public well being director in Weld County, Colorado. The state’s main agriculture county, Weld’s livestock and poultry trade produces about $1.9 billion in gross sales every year.
Patchy Surveillance
In July, the chicken flu unfold from dairies in Colorado to poultry farms. To include it, two poultry operations employed about 650 temporary workers — Spanish-speaking immigrants as younger as 15 — to cull flocks. Inside hot barns, they caught contaminated birds, gassed them with carbon dioxide, and disposed of the carcasses. Many did the hazardous job with out goggles, face masks, and gloves.
By the time Colorado’s well being division requested if staff felt sick, 5 ladies and 4 males had been contaminated. They all had crimson, swollen eyes — conjunctivitis — and a number of other had such signs as fevers, physique aches, and nausea.
State well being departments posted on-line notices providing farms protecting gear, however dairy staff in a number of states told KFF Health News that they’d none. They additionally hadn’t heard concerning the chicken flu, by no means thoughts exams for it.

Studies in Colorado, Michigan, and Texas would later present that chicken flu circumstances had gone beneath the radar. In one analysis, eight dairy staff who hadn’t been examined — 7% of these studied — had antibodies in opposition to the virus, an indication that they’d been contaminated.
Missed circumstances made it not possible to find out how the virus jumped into folks and whether or not it was rising extra infectious or harmful. “I have been distressed and depressed by the lack of epidemiologic data and the lack of surveillance,” stated Nicole Lurie, an govt director on the worldwide group the Coalition for Epidemic Preparedness Innovations, who served as assistant secretary for preparedness and response within the Obama administration.
Citing “insufficient data,” the British authorities raised its assessment of the danger posed by the U.S. dairy outbreak in July from three to 4 on a six-tier scale.
Virologists around the globe stated they had been flabbergasted by how poorly the United States was monitoring the state of affairs. “You are surrounded by highly pathogenic viruses in the wild and in farm animals,” stated Marion Koopmans, head of virology at Erasmus Medical Center within the Netherlands. “If three months from now we are at the start of the pandemic, it is nobody’s surprise.”
Although the chicken flu isn’t but spreading swiftly between folks, a shift in that route may trigger immense struggling. The CDC has repeatedly described the circumstances amongst farmworkers this yr as delicate — they weren’t hospitalized. But that doesn’t imply signs are a breeze, or that the virus can’t trigger worse.
“It does not look pleasant,” wrote Sean Roberts, an emergency providers specialist on the Tulare County, California, well being division in an e-mail to colleagues in May. He described pictures of an contaminated dairy employee in one other state: “Apparently, the conjunctivitis that this is causing is not a mild one, but rather ruptured blood vessels and bleeding conjunctiva.”
Over the previous 30 years, half of round 900 folks recognized with chicken flu around the globe have died. Even if the case fatality price is way decrease for this pressure of the chicken flu, covid confirmed how devastating a 1% dying price could be when a virus spreads simply.
Like different circumstances around the globe, the individual now hospitalized with the chicken flu in Louisiana seems to have gotten the virus instantly from birds. After the case was introduced, the CDC released a statement saying, “A sporadic case of severe H5N1 bird flu illness in a person is not unexpected.”
‘The Cows Are More Valuable Than Us’
Local well being officers had been making an attempt arduous to trace infections, based on tons of of emails from county well being departments in 5 states. But their efforts had been stymied. Even if farmers reported contaminated herds to the USDA and agriculture businesses advised well being departments the place the contaminated cows had been, well being officers needed to depend on farm house owners for entry.
“The agriculture community has dictated the rules of engagement from the start,” stated Michael Osterholm, director of the Center for Infectious Disease Research and Policy on the University of Minnesota. “That was a big mistake.”
Some farmers advised well being officers to not go to and declined to watch their workers for indicators of illness. Sending staff to clinics for testing may depart them shorthanded when cattle wanted care. “Producer refuses to send workers to Sunrise [clinic] to get tested since they’re too busy. He has pinkeye, too,” stated an e-mail from the Weld, Colorado, well being division.
“We know of 386 persons exposed — but we know this is far from the total,” stated an e-mail from a public well being specialist to officers at Tulare’s well being division recounting a name with state well being officers. “Employers do not want to run this through worker’s compensation. Workers are hesitant to get tested due to cost,” she wrote.

Jennifer Morse, medical director of the Mid-Michigan District Health Department, stated native well being officers have been hesitant to use stress after the backlash many confronted on the peak of covid. Describing the 19 rural counties she serves as “very minimal-government-minded,” she stated, “if you try to work against them, it will not go well.”
Rural well being departments are additionally stretched skinny. Organizations specializing in outreach to farmworkers supplied to help well being officers early within the outbreak, however months handed with out contracts or funding. During the primary years of covid, lagging authorities funds for outreach to farmworkers and different traditionally marginalized teams led to a disproportionate toll of the illness amongst folks of shade.
Kevin Griffis, director of communications on the CDC, stated the company labored with the National Center for Farmworker Health all through the summer time “to reach every farmworker impacted by H5N1.” But Bethany Boggess Alcauter, the middle’s director of public well being packages, stated it didn’t obtain a CDC grant for chicken flu outreach till October, to the tune of $4 million. Before then, she stated, the group had very restricted funds for the duty. “We are certainly not reaching ‘every farmworker,’” she added.
Farmworker advocates additionally pressed the CDC for cash to offset staff’ monetary considerations about testing, together with paying for medical care, sick depart, and the danger of being fired. This amounted to a suggestion of $75 each. “Outreach is clearly not a huge priority,” Boggess stated. “I hear over and over from workers, ‘The cows are more valuable than us.’”
The USDA has thus far put greater than $2.1 billion into reimbursing poultry and dairy farmers for losses as a result of chicken flu and different measures to regulate the unfold on farms. Federal businesses have additionally put $292 million into creating and stockpiling chicken flu vaccines for animals and other people. In a controversial decision, the CDC has suggested in opposition to providing those readily available to farmworkers.
“If you want to keep this from becoming a human pandemic, you focus on protecting farmworkers, since that’s the most likely way that this will enter the human population,” stated Peg Seminario, an occupational well being researcher in Bethesda, Maryland. “The fact that this isn’t happening drives me crazy.”
Nirav Shah, principal deputy director of the CDC, stated the company goals to maintain staff protected. “Widespread awareness does take time,” he stated. “And that’s the work we’re committed to doing.”
As President-elect Donald Trump comes into workplace in January, farmworkers could also be even much less protected. Trump’s pledge of mass deportations could have repercussions whether or not they occur or not, stated Tania Pacheco-Werner, director of the Central Valley Health Policy Institute in California.
Many dairy and poultry staff live within the U.S. with out authorization or on short-term visas linked to their employers. Such precarity made folks much less keen to see medical doctors about covid signs or complain about unsafe working situations in 2020. Pacheco-Werner stated, “Mass deportation is an astronomical challenge for public health.”
Not ‘Immaculate Conception’
A swap flipped in September amongst specialists who examine pandemics as nationwide safety threats. A affected person in Missouri had the chicken flu, and nobody knew why. “Evidence points to this being a one-off case,” Shah stated at a briefing with journalists. About a month later, the company revealed it was not.
Antibody exams discovered that an individual who lived with the affected person had been contaminated, too. The CDC didn’t know the way the 2 had gotten the virus, and the potential for human transmission couldn’t be dominated out.
Nonetheless, at an October briefing, Shah stated the general public danger remained low and the USDA’s Deeble stated he was optimistic that the dairy outbreak might be eradicated.
Experts had been perturbed by such assured statements within the face of uncertainty, particularly as California’s outbreak spiked and a child was mysteriously contaminated by the identical pressure of virus discovered on dairy farms.
“This wasn’t just immaculate conception,” stated Stephen Morrison, director of the Global Health Policy Center on the Center for Strategic and International Studies. “It came from somewhere and we don’t know where, but that hasn’t triggered any kind of reset in approach — just the same kind of complacency and low energy.”
Sam Scarpino, a illness surveillance specialist within the Boston space, questioned what number of different mysterious infections had gone undetected. Surveillance outdoors of farms was even patchier than on them, and chicken flu exams have been arduous to get.
Although pandemic specialists had recognized the CDC’s singular maintain on testing for brand new viruses as a key rationalization for why America was hit so arduous by covid in 2020, the system remained the identical. Bird flu exams might be run solely by the CDC and public well being labs till this month, although business and educational diagnostic laboratories had inquired about working exams since April. The CDC and FDA ought to have tried to assist them alongside months in the past, stated Ali Khan, a former high CDC official who now leads the University of Nebraska Medical Center College of Public Health.
As winter units in, the chicken flu turns into tougher to identify as a result of affected person signs could also be mistaken for the seasonal flu. Flu season additionally raises a danger that the 2 flu viruses may swap genes in the event that they infect an individual concurrently. That may type a hybrid chicken flu that spreads swiftly by coughs and sneezes.
A sluggish response to rising outbreaks could merely be a brand new, unlucky norm for America, stated Bollyky, on the Council on Foreign Relations. If so, the nation has gotten fortunate that the chicken flu nonetheless can’t unfold simply between folks. Controlling the virus will probably be a lot tougher and costlier than it could have been when the outbreak was small. But it’s potential.
MICHAEL MITCHELL/BROWN UNIVERSITY PANDEMIC CENTER
Agriculture officers may begin testing each silo of bulk milk, in each state, month-to-month, stated Poulsen, the livestock veterinarian. “Not one and done,” he added. If they detect the virus, they’d want to find out the affected farm in time to cease sick cows from spreading infections to the remainder of the herd — or no less than to different farms. Cows can unfold the chicken flu earlier than they’re sick, he stated, so pace is essential.
Curtailing the virus on farms is the easiest way to forestall human infections, stated Jennifer Nuzzo, director of the Pandemic Center at Brown University, however human surveillance have to be stepped up, too. Every clinic serving communities the place farmworkers stay ought to have quick access to chicken flu exams — and be inspired to make use of them. Funds for farmworker outreach have to be boosted. And, she added, the CDC ought to change its place and provide farmworkers chicken flu vaccines to guard them and keep at bay the prospect of a hybrid chicken flu that spreads rapidly.
The rising variety of circumstances not linked to farms indicators a necessity for extra testing basically. When sufferers are optimistic on a common flu take a look at — a typical diagnostic that signifies human, swine, or chicken flu — clinics ought to probe extra deeply, Nuzzo stated.
The various is a wait-and-see method during which the nation responds solely after monumental harm to lives or companies. This tack tends to depend on mass vaccination. But an effort analogous to Trump’s Operation Warp Speed isn’t assured, and neither is rollout like that for the primary covid pictures, given an increase in vaccine skepticism amongst Republican lawmakers.
Change could as an alternative want to start out from the underside up — on dairy farms, nonetheless the most typical supply of human infections, stated Poulsen. He observed a shift in attitudes amongst farmers on the Dairy Expo: “They’re starting to say, ‘How do I save my dairy for the next generation?’ They recognize how severe this is, and that it’s not just going away.”
