(OPINION) Keith Poulsen’s jaw dropped when farmers showed him images on their cellphones at the World Dairy Expo in Wisconsin in October. A livestock veterinarian at the University of Wisconsin, Poulsen had seen sick cows before, with their noses dripping and udders slack.
But the scale of the farmers’ efforts to treat the sick cows stunned him. They showed videos of systems they built to hydrate hundreds of cattle at once. In 14-hour shifts, dairy workers pumped gallons of electrolyte-rich fluids into ailing cows through metal tubes inserted into the esophagus.
“It was like watching a field hospital on an active battlefront treating hundreds of wounded soldiers,” he said.
Nearly a year into the first outbreak of the bird flu among cattle, the virus shows no sign of slowing. The U.S. government failed to eliminate the virus on dairy farms when it was confined to a handful of states, by quickly identifying infected cows and taking measures to keep their infections from spreading.
Now at least 875 herds across 16 states have tested positive. Experts say they have lost faith in the government’s ability to contain the outbreak.
“We are in a terrible situation and going into a worse situation,” said Angela Rasmussen, a virologist at 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 understand how the bird flu got out of hand, KFF Health News interviewed nearly 70 government officials, farmers and farmworkers, and researchers with expertise in virology, pandemics, veterinary medicine, and more.
Together with emails obtained from local health departments through public records requests, this investigation revealed key problems, including deference to the farm industry, eroded public health budgets, neglect for the safety of agriculture workers, and the sluggish pace of federal interventions.
Case in point: The U.S. Department of Agriculture this month announced a federal order to test milk nationwide. Researchers welcomed the news but said it should have happened months ago — before the virus was so entrenched.
“It’s disheartening to see so many of the same failures that emerged during the covid-19 crisis reemerge,” said Tom Bollyky, director of the Global Health Program at the Council on Foreign Relations.
Far more bird flu damage is inevitable, but the extent of it will be left to the Trump administration and Mother Nature. Already, the USDA has funneled more than $1.7 billion into tamping down the bird flu on poultry farms since 2022, which includes reimbursing farmers who’ve had to cull their flocks, and more than $430 million into combating the bird flu on dairy farms.
In coming years, the bird flu may cost billions of dollars more in expenses and losses. Dairy industry experts say the virus kills roughly 2% to 5% of infected dairy cows and reduces a herd’s milk production by about 20%.
Worse, the outbreak poses the threat of a pandemic. More than 60 people in the U.S. have been infected, mainly by cows or poultry, but cases could skyrocket if the virus evolves to spread efficiently from person to person. And the recent news of a person critically ill in Louisiana with the bird flu shows that the virus can be dangerous.
Just a few mutations could allow the bird flu to spread between people. Because viruses mutate within human and animal bodies, each infection is like 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,” said Tom Peacock, a bird flu researcher at the Pirbright Institute in 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 bird flu, the federal government’s handling of the outbreak reveals cracks in the U.S. health security system that would allow other risky new pathogens to take root.
“This virus may not be the one that takes off,” said Maria Van Kerkhove, director of the emerging diseases group at the World Health Organization. “But this is a real fire exercise right now, and it demonstrates what needs to be improved.”
