Keith Poulsen’s jaw dropped when farmers confirmed him pictures 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 surprised him. They confirmed movies of programs they constructed to hydrate tons of of cattle without delay. In 14-hour shifts, dairy employees pumped gallons of electrolyte-rich fluids into ailing cows by metallic tubes inserted into the esophagus.
“It was like watching a area hospital on an energetic battlefront treating tons of of wounded troopers,” he mentioned.
Nearly a 12 months into the primary outbreak of the chicken flu amongst cattle, the virus exhibits no signal of slowing. The U.S. authorities did not get rid of 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 horrible state of affairs and going right into a worse state of affairs,” mentioned Angela Rasmussen, a virologist on the University of Saskatchewan in Canada. “I don’t know if the chicken flu will change into a pandemic, but when it does, we’re screwed.”
To perceive how the chicken flu obtained out of hand, KFF Health News interviewed almost 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 employees, 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 mentioned it ought to have occurred months in the past — earlier than the virus was so entrenched.
“It’s disheartening to see so most of the identical failures that emerged through the COVID-19 disaster reemerge,” mentioned Tom Bollyky, director of the Global Health Program on the Council on Foreign Relations.

Far extra chicken flu injury is inevitable, however the extent of it is going to 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 might value billions of {dollars} extra in bills and losses. Dairy trade consultants 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 individuals within the U.S. have been contaminated, primarily by cows or poultry, however circumstances might skyrocket if the virus evolves to unfold effectively from individual to individual. And the recent news of an individual critically sick in Louisiana with the chicken flu exhibits that the virus will be harmful.
Just a few mutations might enable the chicken flu to unfold between individuals. 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 solely a 5% probability of a chicken flu pandemic occurring, we’re speaking a few pandemic that in all probability seems like 2020 or worse,” mentioned Tom Peacock, a chicken flu researcher on the Pirbright Institute within the United Kingdom, referring to COVID. “The U.S. is aware of the chance however hasn’t carried out something to sluggish 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 might not be the one which takes off,” mentioned Maria Van Kerkhove, director of the rising illnesses group on the World Health Organization. “But this can be a actual hearth train proper now, and it demonstrates what must be improved.”
A sluggish begin
It might 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 observe 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 wrongdoer.
Long listed amongst pathogens with pandemic potential, the chicken flu’s unprecedented unfold amongst cows marked a worrying shift. It had developed to thrive in animals which can be extra like individuals 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 companies. Collaboration disintegrated nearly instantly.
Farmers nervous the federal government may block their milk gross sales and even demand sick cows be killed, as poultry are, mentioned Kay Russo, a livestock veterinarian in Fort Collins, Colorado.
Instead, Russo and different veterinarians mentioned, they had been dismayed by inaction. The USDA didn’t reply to their pressing requests to assist 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 most important mistake from the USDA was not involving the boots-on-the-ground veterinarians,” Russo mentioned.
Will Clement, a USDA senior adviser for communications, mentioned in an e mail: “Since first studying of H5N1 in dairy cattle in late March 2024, USDA has labored swiftly and diligently to evaluate 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 potentialities, resembling by the air as cows coughed or in droplets on objects, like work boots. But not sufficient knowledge had been collected to understand how precisely it was occurring. 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 worry inside the dairy farmer group that in the event that they change into formally listed as an affected farm, they might lose their milk market,” mentioned 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 crammed information gaps. Zach Riley, head of the Colorado Livestock Association, mentioned 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 mentioned farmers had been contemplating whether or not to put in “floppy inflatable males you see exterior of automotive dealerships” to keep at bay the birds.
Advisories from agriculture departments to farmers had been considerably speculative, too. Officials really helpful biosecurity measures resembling disinfecting tools and limiting guests. As the virus stored spreading all through the summer time, USDA senior official Eric Deeble mentioned at a press briefing, “The response is satisfactory.”
The USDA, the Centers for Disease Control and Prevention, and the Food and Drug Administration offered a united entrance at these briefings, calling it a “One Health” strategy. In actuality, agriculture companies took the lead.
This was express in an e mail from a neighborhood well being division in Colorado to the county’s commissioners. “The State is treating this primarily as an agriculture situation (rightly so) and the general public well being half 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 annually.
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 employees felt sick, 5 ladies and 4 males had been contaminated. They all had crimson, swollen eyes — conjunctivitis — and several other had such signs as fevers, physique aches, and nausea.
State well being departments posted on-line notices providing farms protecting gear, however dairy employees in a number of states told KFF Health News that that they had 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 underneath the radar. In one analysis, eight dairy employees who hadn’t been examined — 7% of these studied — had antibodies in opposition to the virus, an indication that that they had been contaminated.
Missed circumstances made it inconceivable to find out how the virus jumped into individuals and whether or not it was rising extra infectious or harmful. “I’ve been distressed and depressed by the shortage of epidemiologic knowledge and the shortage of surveillance,” mentioned 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 “inadequate knowledge,” the British authorities raised its assessment of the chance posed by the U.S. dairy outbreak in July from three to 4 on a six-tier scale.
Virologists world wide mentioned they had been flabbergasted by how poorly the United States was monitoring the state of affairs. “You are surrounded by extremely pathogenic viruses within the wild and in livestock,” mentioned Marion Koopmans, head of virology at Erasmus Medical Center within the Netherlands. “If three months from now we’re at the beginning of the pandemic, it’s no person’s shock.”
Although the chicken flu just isn’t but spreading swiftly between individuals, a shift in that course might trigger immense struggling. The CDC has repeatedly described the circumstances amongst farmworkers this 12 months as delicate — they weren’t hospitalized. But that doesn’t imply signs are a breeze, or that the virus can’t trigger worse.
“It doesn’t look nice,” 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 that is inflicting just isn’t a gentle one, however fairly ruptured blood vessels and bleeding conjunctiva.”
Over the previous 30 years, half of round 900 individuals identified with chicken flu world wide have died. Even if the case fatality charge is way decrease for this pressure of the chicken flu, COVID confirmed how devastating a 1% demise charge will be when a virus spreads simply.
Like different circumstances world wide, the particular person now hospitalized with the chicken flu in Louisiana seems to have gotten the virus immediately from birds. After the case was introduced, the CDC released a statement saying, “A sporadic case of extreme H5N1 chicken flu sickness in an individual just isn’t sudden.”
‘The cows are extra useful than us’
Local well being officers had been attempting onerous to trace infections, in response to 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 companies 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 group has dictated the principles of engagement from the beginning,” mentioned Michael Osterholm, director of the Center for Infectious Disease Research and Policy on the University of Minnesota. “That was a giant mistake.”
Some farmers advised well being officers to not go to and declined to watch their staff for indicators of illness. Sending employees to clinics for testing might depart them shorthanded when cattle wanted care. “Producer refuses to ship employees to Sunrise [clinic] to get examined since they’re too busy. He has pinkeye, too,” mentioned an e mail from the Weld, Colorado, well being division.
“We know of 386 individuals uncovered — however we all know that is removed from the overall,” mentioned 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 don’t need to run this by employee’s compensation. Workers are hesitant to get examined on account of value,” she wrote.
Jennifer Morse, medical director of the Mid-Michigan District Health Department, mentioned 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 mentioned, “for those who attempt to work in opposition to them, it is not going to go nicely.”
Rural well being departments are additionally stretched skinny. Organizations focusing on outreach to farmworkers provided 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 individuals of shade.
Kevin Griffis, director of communications on the CDC, mentioned the company labored with the National Center for Farmworker Health all through the summer time “to succeed in each farmworker impacted by H5N1.” But Bethany Boggess Alcauter, the middle’s director of public well being applications, mentioned it didn’t obtain a CDC grant for chicken flu outreach till October, to the tune of $4 million. Before then, she mentioned, the group had very restricted funds for the duty. “We are definitely not reaching ‘each farmworker,’” she added.
Farmworker advocates additionally pressed the CDC for cash to offset employees’ monetary considerations about testing, together with paying for medical care, sick depart, and the chance of being fired. This amounted to a proposal of $75 each. “Outreach is clearly not an enormous precedence,” Boggess mentioned. “I hear time and again from employees, ‘The cows are extra useful than us.’”
The USDA has thus far put greater than $2.1 billion into reimbursing poultry and dairy farmers for losses because of the chicken flu and different measures to regulate the unfold on farms. Federal companies 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 available to farmworkers.
“If you need to maintain this from changing into a human pandemic, you concentrate on defending farmworkers, since that’s the most definitely approach that this may enter the human inhabitants,” mentioned Peg Seminario, an occupational well being researcher in Bethesda, Maryland. “The undeniable fact that this isn’t occurring drives me loopy.”
Nirav Shah, principal deputy director of the CDC, mentioned the company goals to maintain employees secure. “Widespread consciousness does take time,” he mentioned. “And that’s the work we’re dedicated 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 may have repercussions whether or not they occur or not, mentioned Tania Pacheco-Werner, director of the Central Valley Health Policy Institute in California.
Many dairy and poultry employees reside within the U.S. with out authorization or on short-term visas linked to their employers. Such precarity made individuals much less keen to see medical doctors about COVID signs or complain about unsafe working circumstances in 2020. Pacheco-Werner mentioned, “Mass deportation is an astronomical problem for public well being.”
Not ‘immaculate conception’
A swap flipped in September amongst consultants who research pandemics as nationwide safety threats. A affected person in Missouri had the chicken flu, and nobody knew why. “Evidence factors to this being a one-off case,” Shah mentioned 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 understand how the 2 had gotten the virus, and the potential of human transmission couldn’t be dominated out.
Nonetheless, at an October briefing, Shah mentioned the general public danger remained low and the USDA’s Deeble mentioned he was optimistic that the dairy outbreak could possibly 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 simply immaculate conception,” mentioned Stephen Morrison, director of the Global Health Policy Center on the Center for Strategic and International Studies. “It got here from someplace and we don’t know the place, however that hasn’t triggered any sort of reset in strategy — simply the identical sort of complacency and low power.”
Sam Scarpino, a illness surveillance specialist within the Boston space, questioned what number of different mysterious infections had gone undetected. Surveillance exterior of farms was even patchier than on them, and chicken flu exams have been onerous to get.
Although pandemic consultants had recognized the CDC’s singular maintain on testing for brand new viruses as a key rationalization for why America was hit so onerous by COVID in 2020, the system remained the identical. Bird flu exams could possibly be run solely by the CDC and public well being labs till this month, despite the fact that business and tutorial diagnostic laboratories had inquired about operating exams since April. The CDC and FDA ought to have tried to assist them alongside months in the past, mentioned 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 might swap genes in the event that they infect an individual concurrently. That might type a hybrid chicken flu that spreads swiftly by coughs and sneezes.
A sluggish response to rising outbreaks might merely be a brand new, unlucky norm for America, mentioned Bollyky, on the Council on Foreign Relations. If so, the nation has gotten fortunate that the chicken flu nonetheless can’t unfold simply between individuals. Controlling the virus can be a lot tougher and costlier than it could have been when the outbreak was small. But it’s attainable.
Agriculture officers might begin testing each silo of bulk milk, in each state, month-to-month, mentioned Poulsen, the livestock veterinarian. “Not one and carried out,” 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 mentioned, so pace is essential.
Curtailing the virus on farms is one of the simplest ways to forestall human infections, mentioned 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 dwell ought to have easy accessibility 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 supply farmworkers chicken flu vaccines to guard them and keep at bay the possibility of a hybrid chicken flu that spreads rapidly.
The rising variety of circumstances not linked to farms alerts a necessity for extra testing normally. When sufferers are optimistic on a basic flu take a look at — a typical diagnostic that signifies human, swine, or chicken flu — clinics ought to probe extra deeply, Nuzzo mentioned.
The various is a wait-and-see strategy during which the nation responds solely after monumental injury to lives or companies. This tack tends to depend on mass vaccination. But an effort analogous to Trump’s Operation Warp Speed just isn’t assured, and neither is rollout like that for the primary COVID pictures, given an increase in vaccine skepticism amongst Republican lawmakers.
Change might as a substitute want to start out from the underside up — on dairy farms, nonetheless the most typical supply of human infections, mentioned Poulsen. He observed a shift in attitudes amongst farmers on the Dairy Expo: “They’re beginning to say, ‘How do I save my dairy for the following era?’ They acknowledge how extreme that is, and that it’s not simply going away.”
