Excessive-ranking federal officers have prompt that fowl flu virus ought to be left to “rip” by way of poultry farms throughout the U.S. — however specialists warn that this hands-off strategy may hasten the start of a brand new pandemic
Robert F. Kennedy Jr., the secretary of Well being and Human Providers, and Brooke Rollins, secretary of Agriculture, have floated the notion that as an alternative of culling birds contaminated with the extremely pathogenic H5N1 virus, farmers ought to let it unfold by way of flocks. The concept is that by doing this, farmers can “determine the birds, and protect the birds, which can be resistant to it,” Kennedy advised Fox Information on March 11.
Now, a perspective piece authored by a gaggle of virologists, veterinarians and well being safety specialists argues that the plan wouldn’t solely be ineffective, however may additionally improve the chance of the virus spilling over into people and sparking a brand new pandemic. The researchers printed their arguments July 3 within the journal Science.
“Primarily, the longer you permit a virus that has proven to be efficient in infecting a number of hosts survive in an atmosphere, the higher the possibility you give it to unfold, to mutate, and to attempt its luck at adaptation,” perspective first-author Erin Sorrell, a virologist on the Johns Hopkins Middle for Well being Safety, advised Reside Science. “Worse case state of affairs, the virus adapts and expands its host vary to change into transmissible in people … Now we’ve a pandemic.”
Chicken flu within the U.S.
H5N1 is a subtype of extremely pathogenic avian influenza (HPAI), a sort of fowl flu that may trigger extreme illness and dying in poultry and different birds. For the reason that virus started spreading broadly amongst U.S. birds in January 2022, the Facilities for Illness Management and Prevention (CDC) has reported that greater than 174 million birds throughout all 50 states have been contaminated with the illness. The virus’s transmission amongst wild aquatic birds, business poultry and yard, hobbyist flocks, has led to huge culls in farms and despatched egg costs skyrocketing.
The virus usually transmits amongst wild birds and poultry, nevertheless it’s recognized to have additionally contaminated greater than 48 mammal species, together with foxes, skunks, raccoons, seals and polar bears. It has additionally unfold to dairy cattle, inflicting outbreaks in additional than 1,000 herds throughout 17 U.S. states, in response to present estimates.

Remoted human instances have been reported amid the continuing outbreak in animals, primarily amongst farm staff, in response to the CDC, though the company states that the present well being danger to most of the people stays low. It is because, whereas the illness can unfold amongst completely different animals, it presently cannot be handed from human to human.
Federal plans
Rollins not too long ago issued updates in regards to the U.S. authorities’s plan to fight the an infection’s unfold and decrease egg costs. The five-pronged technique denotes $500 million to enhance farm biosecurity, $400 million in monetary support to farmers and $100 million for vaccine analysis. The federal government can also be exploring methods to slash laws and improve short-term import choices for eggs.
Present laws state that when infections are detected amongst business poultry, farmers should cull the affected flocks to include the illness’s unfold, for which they’re financially compensated by the U.S. Division of Agriculture (USDA).
But ideas made by officers for extra radical methods to handle fowl flu have left specialists involved. In Might, Kennedy and Dr. Mehmet Oz, the administrator for the U.S. Facilities for Medicare and Medicaid Providers, voiced their help for the homeowners of a Canadian ostrich farm whose 398 birds confronted a cull following confirmed instances of H5N1 fowl flu in December 2024 and January this yr.
“We consider vital scientific information could also be garnered from following the ostriches in a managed atmosphere,” Kennedy wrote in a letter posted to the social platform X and addressed to the pinnacle of the Canadian Meals Inspection Company, which had ordered the cull. Kennedy prompt that the ostriches could have already acquired some “downstream immunity” to the virus, and Oz provided to relocate the birds to his Florida ranch for additional research.
Sorrel advised Reside Science that these statements indicate “there’s nonetheless an expectation that these within the Trump administration, a minimum of on the human well being facet, consider this strategy has advantage.”
However Sorrel and her report collaborators disagree.
Permitting widespread an infection of economic flocks would kill billions of birds, drive poultry and egg costs up, in addition to destabilize native economies and international commerce by way of import restrictions imposed on U.S. merchandise, the authors wrote. Concurrently, it may additionally foster reservoirs of H5N1, growing the virus’ odds of constructing the leap to people — and gaining the power for human-to-human an infection.
“Fast culling of [H5N1] optimistic flocks is central to containment of the virus on a farm,” Sorrel stated. “Poultry contaminated with H5 shed an amazing quantity of virus. If efficient controls designed to mitigate the amount of viral shedding and recognized transmission pathways are eliminated, the publicity danger for different animals and people on website and on neighboring farms will improve, and the chance for H5 to evolve to be a simpler poultry pathogen will increase.”
Kennedy’s proposal can also be impossible to work the best way he is claimed it will — the birds that present eggs and meat on farms are descendants of separate breeding populations and don’t breed themselves. So even when there have been a inhabitants of resilient birds that survived H5N1 an infection, that does not imply they’re passing on their genetic traits to a subsequent era.
What’s extra, the mortality fee of H5N1 is extraordinarily excessive amongst frequent poultry, reaching 100% in home chickens.
What specialists suggest
As an alternative of letting fowl flu tear by way of farms, the scientists suggest that authorities companies ought to improve surveillance of the virus’ unfold, together with enhancing knowledge sharing and outbreak response measures shared between poultry producers, business members and veterinarians. The USDA mustn’t work alone on these measures, Sorrel stated, as “interdisciplinary groups have to have the authority and means by which to activate on the state and federal ranges.”
Different specialists agree with the group’s ideas, though they highlighted areas that want additional dialogue. Dr. Rocio Crespo, a poultry veterinarian on the North Carolina State College School of Veterinary Drugs, advised Reside Science that additional particulars on potential vaccine methods and biosecurity at farms ought to be explored.
However the USDA is now going through billions of {dollars} in federal funding cuts, and Crespo says that offering financial help to farmers going through outbreaks — alongside making investments to know fowl flu evolution, preventive measures and management strategies — may change into more and more tough.
“The present insurance policies on poultry farms are efficient at stopping unfold to different farms,” Crespo advised Reside Science. “Nonetheless, the USDA’s strategy doesn’t think about spill over and influences from different crop or animal agricultural actions.”
“It seems we’re persevering with with the identical methods with out adequate enchancment,” she added. “Larger transparency and collaboration is essential.”
