Amid bird flu spread, experts reveal if it's safe to drink milk: 'Indirect concern'
CDC issues alert over bird flu case
Fox News medical contributor Dr. Marc Siegel on what to know about bird flu and why it is important to not look directly at the solar eclipse without proper glasses
Traces of bird flu have been detected in pasteurized milk — leaving many people wondering if it’s safe to drink.
The U.S. Food and Drug Administration (FDA) released a notice on Thursday stating that one in five retail samples of commercial milk tested positive for fragments of highly pathogenic avian influenza (HPAI), more commonly known as bird flu or avian flu.
The share of milk with viral remnants was higher in areas where herds of cattle had been infected.

The presence of the virus in the milk doesn’t necessarily mean there is a risk to consumers, however, the FDA noted.
“Additional testing is required to determine whether an intact pathogen is still present and if it remains infectious, which would help inform a determination of whether there is any risk of illness associated with consuming the product,” the agency stated.

“Although bird flu viruses do not normally infect humans, sporadic human infections have occurred,” the FDA stated in the alert.
Pasteurization eliminates risk, experts say
Before milk can be sold commercially, government regulations require that it is pasteurized.
During the pasteurization process, raw milk is heated to a certain temperature for a brief period of time and is then chilled again, according to the International Dairy Foods Association (IDFA) website.
This process kills any pathogens and ensures that milk is safe to drink.
BIRD FLU VIRUS FOUND IN GROCERY STORE MILK, BUT NO RISK TO CUSTOMERS, FDA SAYS
Dr. Scott Pegan, professor of biomedical sciences at the University of California, Riverside and a biochemist for the United States Medical Research Institute of Chemical Defense, said the FDA’s finding does not mean there is any direct risks to consumers.
“In the U.S., commercial intrastate sold milk is required to be pasteurized,” he told Fox News Digital. “This process is geared to kill viruses like H5N1 and other bacteria that can pose a threat to human health.”

“Milk that has been pasteurized is safe and there is no current reason to avoid it or other pasteurized milk products based on the FDA’s findings,” Pegan went on.
“However, there is a substantial risk of consuming unpasteurized milk and products of that milk.”
Even after viruses and bacteria have been killed in pasteurized milk, remnants can remain in the milk, he said — but they are not dangerous.
RARE HUMAN CASE OF HIGHLY CONTAGIOUS BIRD FLU CONFIRMED IN TEXAS
Edward Liu, M.D., chief of infectious diseases at Hackensack Meridian Jersey Shore University Medical Center in New Jersey, agreed that there is not a risk associated with drinking pasteurized milk.
“The pasteurization is the key — the heat treatment kills off the viruses,” he told Fox News Digital. “Although the FDA’s testing picked up fragments [of the virus], the heating process destroyed it, so it’s not able to infect people.”

The fragments alone are not enough to cause any kind of infection, he confirmed.
“I think the key word is ‘fragments.’ Just like with COVID, if you do a PCR test a month later, we’ll detect little fragments of the virus, but it’s not active anymore,” Liu said.
“So if the virus isn’t entirely intact, it shouldn’t be able to infect you.”
Any sporadic cases of human infection would likely occur when a farmer is handling birds directly, Liu said.
Consumers should avoid drinking raw milk that has not been pasteurized, the FDA said.
“There are some people who like to go all natural, but pasteurization has been used for decades for safety,” he said. “Some degree of processing is actually better and safer for us.”
Animals pose greater concern, experts say
The “indirect concern” within the scientific and medical community involves the increased risk of “spillover” to humans from animals with the H5N1 virus, said Pegan.
“Prior to the outbreak in dairy cattle, this concern principally revolved around the risk of transmission to humans from wild birds or poultry,” he told Fox News Digital.

“The presence of H5N1 avian flu in the milk of these cattle shows that cattle may be able to provide a new reservoir for this virus, increasing the odds of exposure to those in direct contact with the infected cattle.”
The more animals that are infected, the higher chance that humans may come in direct contact with the virus — which likely would lead to a greater number of human cases, said Pegan.

“The case of cattle-to-human transmission seen in Texas is in line with this concern,” he noted.
“Also, the more mammals infected increases the chances that the virus will adapt to other mammals, such as humans.”
FDA’s recommendations
The FDA restated its “long-standing recommendation” that consumers avoid drinking raw milk that has not been pasteurized.
The agency also recommends that companies refrain from manufacturing or selling raw milk or raw milk products made with milk from cows that tested positive for bird flu, were exposed to the virus or showed symptoms of illness.
“Over the past few years, there has been an increased consumer demand for these unpasteurized products,” Pegan said.

“While not allowed to be sold via interstate brands, some states have relaxed local sales of these products at farmer’s markets and similar outlets,” he said.
“Individuals may want to avoid those unpasteurized products until more information is obtained about this H5N1 avian flu outbreak in dairy cattle.”

The FDA also urged producers to “take precautions” when discarding milk from affected cows, “so that the discarded milk does not become a source of further spread.”
So far, only one person has been confirmed to have contracted the virus after exposure to infected cows, the FDA stated.
“The CDC says the risk to the general public remains low,” the agency said.
“The FDA and USDA continue to indicate that, based on the information we currently have, our commercial milk supply is safe.”
Fox News Digital reached out to the National Milk Producers Federation, the American Dairy Association and the International Dairy Foods Association for comment.

A look back at the medical miracles of 2025
Fox News senior medical analyst Dr. Marc Siegel joins ‘Fox & Friends’ to highlight 2025 breakthroughs, from a pineapple-derived burn cream to a newly approved heart procedure.
NEWYou can now listen to Fox News articles!
America has been at the forefront of medical innovation since the nation’s founding in 1776.
From groundbreaking surgeries to cancer breakthroughs, U.S. physicians have helped transform nearly every field of medicine.
As America marks its 250th anniversary, experts are highlighting some of the most influential medical innovations in the nation’s history.
No. 1: Orthopedic care
John Uribe, MD, orthopedic surgeon and system chief executive at Baptist Health Orthopedic Care in Florida, said he believes the greatest breakthrough in orthopedics is the evolution of joint replacement surgery, particularly of the hip and knee.
AMERICA’S LIFESPAN HAS DOUBLED SINCE 1776 — EXPERTS REVEAL WHAT CHANGED
“A generation ago, severe arthritis or joint damage often meant a lifetime of pain, limited mobility and loss of independence,” he told Fox News Digital.
“Today, orthopedic surgeons can replace a damaged joint with highly durable implants, use advanced imaging and navigation, and increasingly rely on robotic-assisted technology to personalize implant positioning and improve precision.”
“The future of orthopedics will be less one-size-fits-all and more focused on matching the right procedure, implant, recovery plan and technology to the individual patient,” a doctor said. (iStock)
Today, patients can walk the same day after joint replacement, return home sooner and recover with less disruption than in the past, according to Uribe.

“Hip and knee replacements, arthroscopic procedures, advanced fracture care and spine treatments have allowed patients to stay active longer and maintain independence as they age,” the doctor said. “The biggest impact is that orthopedic care can give people back parts of their lives they thought they had lost.”
“For many patients, the goal is no longer just to relieve pain; it is to restore movement, independence and quality of life.”
No. 2: Mental health treatment
For most of America’s 250 years, mental illness was largely treated indirectly with medication, or not at all when medication was ineffective, according to Dr. Russ Voltin, a West Virginia-based practicing psychiatrist and medical consultant at BrainsWay.
The biggest breakthrough, Voltin told Fox News Digital, has been neuromodulation therapies like deep transcranial magnetic stimulation (TMS), which are “clinically proven to non-invasively target the brain circuits involved in conditions such as depression and OCD, helping rebalance neural activity at its source.”
“Mental health is brain health, and for the first time, we have treatments designed to address it that way.”

A generation ago, a patient who didn’t respond to medication had very limited options, he said.
“Today, a clinician can offer noninvasive brain stimulation in an outpatient chair – no anesthesia, no sedation, none of the prominent side effects of medication, and all with limited lifestyle interruption.”
The FDA recently expanded clearance for an accelerated Deep TMS protocol that shortens the initial phase of depression treatment from about four weeks of daily visits to just six treatment days.
“Mental health is brain health, and for the first time, we have treatments designed to address it that way.”
“For someone in a depressive crisis, this is the difference between waiting and getting better,” the expert said.
In clinical trials, roughly 78% of patients reached remission and more than 80% were still in remission a full year later.
“The biggest shift is that for people who once cycled through medication after medication with no relief, durable recovery is now a realistic goal rather than a hope.” (iStock)
“As a clinician, that last figure is the one that matters most: People going back to work, repairing relationships and re-entering their own lives, not just scoring better on a questionnaire,” Voltin said.
“The biggest shift is that for people who once cycled through medication after medication with no relief, durable recovery is now a realistic goal rather than a hope.”
No. 3: Cancer care
Cancer care has advanced dramatically over the past 250 years, with breakthroughs in prevention, screening, diagnosis and treatment transforming patient outcomes.
Leonard Kalman, MD, acting system chief executive at Baptist Health Cancer Care and acting executive medical director at Baptist Health Herbert Wertheim Cancer Institute in South Florida, said one of the most important breakthroughs in oncology is the understanding that “at its core,” cancer is a genetic disease.
Today, physicians can cure certain leukemias and lymphomas that were “once far more difficult to treat,” an expert noted. (iStock)
“Cancer can be driven by inherited germline mutations or by somatic mutations that occur in normal tissue and lead cells to become malignant,” he told Fox News Digital. “That discovery has transformed how we understand, diagnose and treat cancer.”
Today, physicians can cure certain leukemias and lymphomas that were “once far more difficult to treat,” the doctor noted.
NEW BLOOD TEST DETECTS 90% OF AGGRESSIVE PROSTATE CANCER CASES, BEATING CURRENT SCREENINGS
“We can also extend life while preserving quality of life for many patients with metastatic cancers — including diseases such as lung cancer, melanoma and prostate cancer, where treatment options were much more limited a generation ago,” Kalman said.
Many of those advances have shifted cancer care toward more individualized treatment, allowing physicians to tailor therapies based on a patient’s specific disease.
“For many patients, the goal is no longer just to relieve pain; it is to restore movement, independence and quality of life.”
“Advances in targeted therapies, immunotherapy, molecular testing and supportive care allow physicians to better personalize treatment, manage side effects and help patients live longer with a better quality of life, even when cancer has spread beyond the primary tumor,” the doctor said.
No. 4: Cardiovascular care
Tom Nguyen, MD, system chief executive at Baptist Health Heart & Vascular Care and chief medical executive at Baptist Health Miami Cardiac & Vascular Institute in South Florida, highlighted the ability to diagnose heart disease earlier and treat “even the most complex conditions” with safer, more precise and less invasive therapies.
“Cardiovascular disease remains the leading cause of death worldwide, but patients who once might have died in their 40s or 50s are now routinely living into their 80s and 90s with an excellent quality of life,” he told Fox News Digital.

Procedures like open-heart surgery, coronary artery bypass surgery, coronary stents, catheter-based valve replacement, advanced imaging and robotic heart surgery have “completely transformed what is possible,” according to Nguyen.
“Robotic heart surgery is a powerful example of how far the field has come,” he said. “For appropriately selected patients, surgeons can now perform highly complex heart procedures through much smaller incisions using robotic technology that provides exceptional visualization, precision and control.”
TEST YOURSELF WITH OUR LATEST LIFESTYLE QUIZ
The biggest achievement, Nguyen said, is not only helping people live longer, but also helping them “live better.”
“Today, heart and vascular specialists can perform procedures that would have seemed almost unimaginable just one generation ago,” he said. “Patients are surviving heart attacks, valve disease, rhythm disorders and complex vascular conditions at rates that would have been difficult to imagine decades ago.”
“Many complex cardiac operations that once required opening the chest can now be performed through small incisions, or robotically – allowing patients to recover much faster with less pain and disruption to their lives,” a doctor said. (iStock)
Success isn’t measured only by survival, Nguyen added. “Our ultimate goal is to help patients feel better and return to the lives they enjoy.”
No. 5: Neurology
Michael McDermott, MD, system chief executive of Baptist Health Brain & Spine Care and chief medical executive at Baptist Health Miami Neuroscience Institute, said the ability to safely operate on the brain is the greatest advancement in American neuroscience.

“Less than a century ago, a craniotomy was an extraordinarily risky operation, and survival itself was far from guaranteed,” he told Fox News Digital. “Today, advances in anesthesia, electrocautery, imaging, surgical navigation, brain mapping and intraoperative neurophysiologic monitoring have transformed brain surgery into a highly precise and much safer procedure.”
The ability to treat acute stroke in real time has been “equally transformative,” McDermott noted.
The growth of artificial intelligence is “beginning to transform spine surgery,” a neurologist said, by helping physicians identify which patients are “most likely to benefit from complex corrective procedures and by allowing implants to be precisely modeled before surgery.” (iStock)
“Using advanced imaging and mechanical thrombectomy, physicians can now remove a clot from the brain and restore blood flow before permanent damage occurs in many eligible patients,” he said. “At the same time, innovations such as high-intensity focused ultrasound for essential tremor demonstrate how neuroscience has become increasingly precise and less invasive.”

Today, neuro experts can accomplish tasks that “would have been difficult to imagine just one generation ago,” McDermott noted.
“We can remove blood clots from the brain during an active stroke, implant deep brain stimulation devices for Parkinson’s disease, and perform highly sophisticated brain and spine surgery using advanced imaging, navigation and artificial intelligence,” he said.
Medical advancements have improved quality of life in patients with brain tumors and spinal complications. (iStock)
Advances like image-guided surgery, intra-operative brain mapping, neurophysiologic monitoring and radio-surgery allow surgeons to remove tumors more safely while protecting areas of the brain responsible for movement, speech and other critical functions, he said.

Beyond brain tumors, other advances across neuroscience, like corrective spine surgery, have allowed doctors to restore posture and mobility in patients with severe spinal deformities. Meanwhile, focused ultrasound can “significantly reduce tremors that interfere with everyday activities such as writing, eating or drinking,” McDermott noted.
“Increasingly, our goal isn’t simply to help patients survive – we’re helping them maintain their independence, preserve function and return to the lives they want to live.”

West Nile virus detected in southern state as health officials warn residents about mosquitoes
NEWYou can now listen to Fox News articles!
Health officials in Nashville are urging residents to protect themselves from mosquito bites after West Nile virus was detected in mosquitoes for the first time this year.
The Metro Public Health Department (MPHD) announced the virus was found in a mosquito pool collected near Cass Street in North Nashville, marking the city’s first detection of West Nile virus in 2026 and the earliest positive mosquito sample of the season.
The detection comes after health officials reported elevated West Nile virus activity in mosquito pools during 2025, when one human case of the virus was confirmed.
“We can all play a role in reducing the presence of mosquitoes in our community, making our outdoor areas both more pleasant and safer from mosquito-borne diseases like West Nile virus,” Dr. Sanmi Areola, director of health at the Metro Public Health Department, said in a statement to Fox 17.

“As our team educates those in the area where West Nile virus was found, we hope the rest of our community does what they can to protect themselves and their families from mosquitoes this summer.”
According to the Centers for Disease Control and Prevention, West Nile virus is the leading mosquito-borne disease in the United States. Most people infected with the virus do not develop symptoms, but about one in five experience fever, headaches, body aches, vomiting, diarrhea or a rash. Fewer than 1% develop a serious neurological illness that can affect the brain or spinal cord, with older adults and people with weakened immune systems facing the greatest risk.
Public health officials routinely trap and test mosquitoes throughout the summer to monitor for West Nile virus activity. A positive mosquito sample does not necessarily mean people in the area will become infected, but it serves as an early warning that the virus is circulating locally.
In response to the positive test, MPHD said crews are distributing educational flyers in the affected neighborhood, increasing mosquito trapping, monitoring standing water and applying larvicide where needed to help reduce mosquito populations. The department said it does not spray insecticide to kill adult mosquitoes.

Residents can also request a free backyard inspection from the department’s Pest Management team to identify areas where mosquitoes may be breeding.
Health officials recommend eliminating standing water from bird baths, flowerpots, buckets, old tires, children’s toys and other outdoor containers where mosquitoes lay eggs. Trimming overgrown vegetation around homes can also help reduce mosquito activity.

To help prevent mosquito bites, the health department recommends using EPA-approved insect repellents containing DEET, picaridin or oil of lemon eucalyptus, wearing long sleeves and pants outdoors during peak mosquito hours around dusk and dawn, and making sure window and door screens are in good repair.
Officials said reducing mosquito breeding around homes can help lower the risk of West Nile virus and other mosquito-borne illnesses throughout the community.
