  • Urgent Warning: Avian Flu Threat Rises from Unpasteurized Dairy Products in the US

    Urgent Warning: Avian Flu Threat Rises from Unpasteurized Dairy Products in the US
    Sep 14 2025
    The Centers for Disease Control and Prevention released new warnings this week highlighting the continued risk of bird flu, also known as H5N1, spreading through unpasteurized dairy products in the United States. The CDC stated the risk of infection from consuming raw milk remains low but should be taken seriously, especially for vulnerable groups like children, the elderly, and those with weakened immune systems. Several human illnesses in the U.S. have been linked to occupational exposure in the dairy and poultry industries, but there have also been infections with no clear source. Some of these unexplained cases involved individuals who consumed raw milk before becoming ill, and outbreaks have led to recalls of raw milk and pet food found contaminated with the virus, as reported by Food Safety News.

    While there have not been any confirmed deaths in humans definitely tied to raw milk consumption, the CDC stresses that pasteurization is critical in eliminating the risk of infection from dairy products. The agency also urges Americans to cook poultry, eggs, and beef thoroughly to reduce the chances of foodborne avian flu infection.

    The avian influenza outbreak is not limited to the United States. Globally, H5N1 continues to devastate wild birds, poultry, and mammals. In response, the UN Food and Agriculture Organization convened an international group of experts in Brazil this week. This unprecedented meeting aims to coordinate worldwide strategies on prevention, early warning, vaccination, biosecurity, and response, with special attention given to protecting low-income and backyard poultry settings. FAO leadership emphasized that avian flu is now a global challenge requiring science-based cooperative action.

    Marine mammals have also been hit hard by the virus. The New York Times reports veterinarians in California have started a small trial of bird flu vaccines in rescued northern elephant seals. This research is urgent, as similar outbreaks have caused mass die-offs, including the deaths of over 17,000 seal pups in Argentina last year. The results of these studies could influence the decision to vaccinate endangered Hawaiian monk seals, which face a real risk from the virus as migratory birds continue to spread it across regions.

    Currently, the CDC continues to monitor for signs of human-to-human transmission in the United States, and so far, none have been identified according to CDC’s FluView weekly update.

  • Soaring Concerns: Monitoring the Spread of Avian Influenza Across the U.S. and Globe

    Soaring Concerns: Monitoring the Spread of Avian Influenza Across the U.S. and Globe
    Sep 13 2025
    The United States continues to monitor the ongoing spread of bird flu, with new cases and evolving risks reported across the country. On September 10, the Montana Department of Livestock confirmed that a domestic poultry flock in north central Montana tested positive for highly pathogenic avian influenza, marking the latest in a series of outbreaks affecting both backyard and commercial operations. Maryland authorities also reported a new case this week in Anne Arundel County, the third detection in that county this year, and part of a larger pattern seen throughout the region, according to CBS News. This year alone, more than 36 million commercial egg-laying hens have been lost to outbreaks, contributing to earlier spikes in egg prices, though costs have stabilized since the worst months of January and February.

    Health agencies remain alert to potential human health impacts. The Centers for Disease Control and Prevention recently reiterated warnings about the risks associated with consuming raw and unpasteurized milk. Although no human cases have been conclusively linked to drinking raw milk in the U.S., the CDC notes that a small number of human avian flu infections have occurred, primarily among poultry and dairy workers. A CDC research update this week highlighted that the virus could theoretically infect the human gastrointestinal tract if contaminated food or beverages are ingested, but overall risk remains low. Still, the CDC strongly advises choosing pasteurized milk and cooking poultry and eggs thoroughly, as eating or drinking contaminated raw animal products has led to illness in animals and could pose a threat to sensitive groups, including children, the elderly, and those with weakened immune systems.

    Globally, bird flu remains a heightened concern. According to the UN Food and Agriculture Organization this week, international experts are meeting in Brazil to coordinate a response, calling for improved surveillance, vaccination strategies, and biosecurity efforts as the virus spreads rapidly among wild birds, livestock, and even marine mammals. The New York Times reports that scientists in California have begun testing bird flu vaccines in rehabilitated northern elephant seals, following devastating losses among marine mammal populations in South America. If successful, this program may soon extend to endangered Hawaiian monk seals, a species scientists warn could be especially vulnerable to avian flu as migratory birds arrive this season.

    That’s the latest on the bird flu situation in the U.S. and worldwide. Thank you for tuning in, and be sure to come back next week for more updates. This has been a Quiet Please production. For more, check out Quiet Please dot AI.

  • Navigating the Unpredictable Landscape: Monitoring the H5N1 Avian Flu Outbreak in the United States

    Navigating the Unpredictable Landscape: Monitoring the H5N1 Avian Flu Outbreak in the United States
    Sep 11 2025
    The United States continues to monitor the bird flu, also known as H5N1, as new developments emerge this week. The Centers for Disease Control and Prevention confirmed that as of mid-2025, there have been 70 confirmed human infections and just one fatality nationwide. Most recent human cases, including a cluster of 37 in California, have been mild and no human-to-human transmission has been documented. A new CDC report published September 8 details how influenza A viruses—including H5N1—may infect the gastrointestinal tract of mammals, highlighting a low but possible risk from consuming virus-contaminated food and beverages. While there have been no documented cases from drinking raw milk, health officials continue to urge caution, with warnings that consuming raw, unpasteurized dairy products remains a theoretical but preventable exposure risk.

    The USDA announced this week that Minnesota's dairy herds are now officially unaffected by bird flu after months of testing, further reducing new state-level animal outbreaks. However, Texas, Arizona, California, Nevada, and Idaho still have affected herds and will continue enhanced surveillance and restrictions. According to the Center for Infectious Disease Research and Policy, a historic outbreak at a Texas dairy early last year contributed to a growing total of 1,079 infected herds across 17 states. New animal detections have been sparse in the past month, but South Dakota confirmed another outbreak at a large turkey farm.

    In California, investigators remain perplexed by the source of a recent H5N1 infection in a school-age child who had no known exposure to cattle or poultry, underscoring the virus's unpredictable nature and ongoing threat. The child’s illness was linked via sequencing to the same H5N1 genotype circulating in dairy cattle and other animals, but no human transmission to close contacts was found. These rare human cases without known animal contact have prompted public health labs, especially in California, to increase subtyping and surveillance of influenza A positive samples, including in individuals without known exposure to livestock.

    Globally, the United Nations Food and Agriculture Organization convened a major meeting in Brazil this week, bringing together experts to respond to what they now call a global avian flu challenge. Their focus is improving prevention, early warning systems, and vaccine strategies, with an emphasis on international collaboration.

  • "Soaring Concerns: Resurgence of H5N1 Bird Flu Across the U.S. and Globally"

    "Soaring Concerns: Resurgence of H5N1 Bird Flu Across the U.S. and Globally"
    Sep 9 2025
    Bird flu is again making headlines in the U.S. this week after federal authorities identified a new case of H5N1 infection in a Texas dairy herd, the first reported in that state since May. The U.S. Department of Agriculture now counts 1,079 herds across 17 states that have been impacted since early 2024. According to the Center for Infectious Disease Research and Policy, this detection marks a continued threat, coming at a time when researchers still cannot pinpoint how a recent California child contracted the virus in an urban setting, despite genetic links to the dairy cow outbreak.

    Meanwhile, the CDC has tracked a total of 70 confirmed human infections in the U.S. since the outbreak began in 2024, most cases resulting in mild symptoms such as eye and respiratory problems. No human-to-human transmission has been identified to date, and just one fatality has been reported in the U.S. by mid-2025, though experts highlight that undetected cases may exist due to limited testing. A recent study from the University of Maryland Institute for Health Computing emphasizes that, without broader surveillance, infected individuals with mild symptoms could go unnoticed, increasing the importance of quick action and real-time testing.

    Poultry farms have also been hit: just this past week, turkey outbreaks were recorded at commercial farms in North and South Dakota, highlighting that the virus is still circulating in U.S. flocks. According to Food Business Middle East, the ongoing bird flu outbreaks have continued to disrupt the global poultry trade, prompting the UN's Food and Agriculture Organization to host a major meeting in Brazil this week.

    Globally, Europe is facing a renewed surge with new bird flu outbreaks in Portugal and Germany, affecting wild birds, poultry, and even mammals like red foxes and otters. Human cases remain rare worldwide, with the European Centre for Disease Prevention and Control reporting 42 cases between December 2024 and June 2025, most tied to direct contact with infected animals. No sustained human-to-human spread has been observed, but the mutation and adaptability of the virus remains a concern for health officials.

    As the outbreak’s impact continues to unfold, health experts and regulators urge ongoing vigilance—from testing and surveillance in both animals and humans to strict biosecurity on farms and prompt containment where outbreaks emerge. That’s your update on bird flu across the U.S. and the globe.

  • Deadly Bird Flu Outbreak Ravages U.S. Poultry Industry

    Deadly Bird Flu Outbreak Ravages U.S. Poultry Industry
    Sep 7 2025
    Bird flu continues to make headlines across the United States, with new outbreaks reported in both backyard and commercial flocks. Georgia agriculture officials announced on Friday that a backyard flock in metro Atlanta tested positive for the highly contagious H5N1 avian influenza strain. This marks the second confirmed case in a Georgia backyard flock this year and highlights ongoing concerns for both backyard and commercial poultry operations. According to the U.S. Department of Agriculture, since 2022, more than 175 million birds have been affected nationwide, making this the deadliest animal disease outbreak in U.S. history.

    Recent CDC surveillance confirms that human infections remain rare, with 70 confirmed cases and one fatality in the U.S. by mid-2025. However, researchers at the University of Maryland Institute for Health Computing warn that undetected cases may exist due to limited testing for individuals exposed to infected birds and farm animals. Their use of generative AI revealed several high-risk patients whose potential infections went unnoticed, underscoring gaps in the national detection strategy.

    The risk to commercial operations remains high. In the last week, turkey farms in North Dakota and South Dakota have reported fresh outbreaks—the first known commercial cases in the country in several months. The rapid response by agriculture officials aims to contain further spread, with increased monitoring and possible culling operations likely in affected zones.

    Experts anticipate additional outbreaks as wild bird migration picks up this fall. Data transparency is an ongoing issue. Scientists, including those at UC Davis, argue that farm-level data should be shared more widely to improve outbreak tracking and research, but confidentiality practices still silo much critical information. This hampers efforts to fully understand how the virus moves between bird populations and across regions.

    Globally, bird flu remains a concern. The World Health Organization recently noted ongoing H5N1 transmission in wildlife and occasional spillover events in Europe and Asia. New variants remain under scrutiny for any signs of increased human transmissibility.

    While the overall threat to the general public remains low, experts urge continued vigilance among poultry farmers, wildlife handlers, and health care systems. Early detection, rapid containment, and clear communication are key to preventing larger outbreaks and protecting the nation’s food supply.

  • Alarming Resurgence of H5N1 Bird Flu in the U.S. - Experts Warn of Potential Threat

    Alarming Resurgence of H5N1 Bird Flu in the U.S. - Experts Warn of Potential Threat
    Sep 6 2025
    The United States is once again on alert as cases of H5N1 bird flu re-emerge in both livestock and humans, with the most recent detection reported just yesterday in a Texas dairy herd. According to CIDRAP, this is the first Texas case since May and brings the national total to 1,079 affected dairy herds across 17 states since early 2024. The USDA also confirmed another H5N1 outbreak in a commercial turkey flock in South Dakota, following closely on the heels of additional detections in North Dakota and Georgia.

    No clear sources have been found for some of the human cases connected to recent animal outbreaks. Investigators in California, working with the CDC, are still unable to determine how a school-age child in San Francisco contracted H5N1 in December 2024, despite comprehensive testing of close contacts and potential environmental sources. The CDC’s report highlights that 37 of the country’s 66 confirmed human infections since 2024 have been tied to California, but no evidence of sustained human-to-human transmission has been documented.

    The CDC notes that, so far, recent U.S. human infections have resulted in mild illness only. Nationally, there have been 70 confirmed cases and just one fatality as of mid-2025, although experts at the University of Maryland urge caution. They warn that limited testing and surveillance could mean additional cases are going undetected, especially among those with flu-like symptoms and a history of animal exposure.

    Globally, the bird flu situation remains dynamic. Between January and August, 30 human H5N1 cases were reported across eight countries, with Cambodia and Bangladesh experiencing the most significant numbers, according to the International Centre for Diarrhoeal Disease Research in Bangladesh. Europe has also seen a recent rise in outbreaks, as Germany and Portugal reported more than 1,100 birds culled after confirmed infections.

    In the U.S., the virus continues to circulate in wild birds, poultry, and now dairy cows, making this the longest and deadliest animal disease outbreak in the nation's history, according to reporting from Sentient Media. With fall migration patterns set to begin, experts expect further bird flu activity in the coming months. The CDC, FDA, and state agencies all emphasize the need for strong surveillance and continued cross-species monitoring to guard against a broader human health threat.

  • Avian Influenza Outbreak Strikes South Dakota Turkey Farm, Sparking Vigilance

    Avian Influenza Outbreak Strikes South Dakota Turkey Farm, Sparking Vigilance
    Sep 4 2025
    U.S. agricultural and public health authorities are on alert as a new outbreak of highly pathogenic avian influenza, commonly called bird flu, strikes a large commercial turkey farm in Faulk County, South Dakota. The USDA reports that this is the most recent U.S. case since early July, with 55,400 turkeys affected as of August 28. The infected birds have been euthanized to contain the virus, and a strict control zone is now in force to prevent further spread. According to South Dakota Public Broadcasting, this marks the state’s first confirmed bird flu case since May, ending nearly two months of relative calm in poultry operations.

    National surveillance efforts continue as the CDC and the USDA monitor for potential human and animal cases. The CDC has updated its situation summary and reassures the public that, so far, there are no new human infections linked to this Farm outbreak. However, federal and state health officials remain vigilant, especially as autumn migration of wild birds can cause the virus to spread more widely.

    In related developments, the FDA issued a warning this week after confirming the presence of the H5N1 strain of bird flu in certain lots of frozen raw cat food produced by RAWR, sold under the name Chicken Eats. The investigation began after a cat in San Francisco fell ill and was ultimately euthanized following consumption of the product. Whole genome sequencing confirmed that the strain found in the cat matched the virus identified in the chicken-based pet food lots with sell-by dates in September and October. The FDA has linked previous similar infections of domestic cats to other raw poultry-based pet foods, raising fresh concerns about the risks of feeding animals uncooked meat products. So far, there have been no U.S. cases detected in dogs, though the FDA notes that both pet cats and some wild mammals are at risk, especially those that are very young, elderly, or have weakened immune systems.

    Globally, animal health officials continue to monitor bird flu flare-ups, particularly as migratory patterns shift. While no major new outbreaks outside of the U.S. have been reported in the past 24 hours, authorities remain on heightened alert ahead of the colder months when flu viruses typically increase in both animals and people.

  • Stable Outlook for US Bird Flu Cases, but Ongoing Concerns Globally

    Stable Outlook for US Bird Flu Cases, but Ongoing Concerns Globally
    Sep 2 2025
    The latest updates on the bird flu, or H5N1 avian influenza, indicate the situation remains concerning but largely stable for human cases, especially in the United States. According to a Monday, September 1 Bird Flu Bulletin, the Centers for Disease Control and Prevention (CDC) reported no new human H5N1 infections in the US since mid-February. The worldwide tally since January holds at 26 confirmed human cases, the majority in Cambodia, with eight fatalities. Cambodia is under particular scrutiny as a hotspot, with health agencies emphasizing risks for those in direct contact with poultry.

    Despite the low risk of human-to-human transmission, the virus continues to circulate actively among animals. The US Department of Agriculture has noted ongoing outbreaks in wild birds and poultry, especially in states along migratory routes. There have also been recent detections in feral and domestic cats across several states, though federal officials stress that cats are generally dead-end hosts with minimal risk of wider transmission, while highlighting the broad mammalian reach of this year’s strain.

    Globally, the Food and Agriculture Organization confirms sporadic spillover into mammal species, with farm biosecurity notably ramping up. There has been an uptick in farmers and veterinarians seeking booster vaccinations for livestock, and China’s latest vaccine rollout for poultry has demonstrated promising efficacy in curbing outbreaks across Asia. As animal cases increase, many countries are taking protective measures and tightening surveillance.

    While the CDC officially ended its emergency response in July due to the stabilization of H5N1 in animals, the highly pathogenic strain still poses significant biosecurity challenges. The 2024-2025 outbreak has affected over 100 million birds across North America, devastating poultry farms and increasing costs for both producers and consumers. The primary transmission route remains through contact with migratory wild birds, underscoring the difficulty in fully containing the virus on large commercial farms.

    In research developments, a University of Maryland team has developed an artificial intelligence tool that scans medical records for signs of potential H5N1 exposure, aiming for earlier detection even when symptoms overlap with other respiratory diseases. Lead author Katherine Goodman notes that undetected infections are possible due to gaps in monitoring, making ongoing vigilance critical.

    As World Health Organization leadership has warned, the risk of a new pandemic from avian or other zoonotic flus remains real, and high mortality strains like H5N1 are being watched closely around the world.
