Americans Unaware of Raw Milk Dangers: Survey Reveals Alarming Knowledge Gap

Discover the hidden dangers of raw milk. Are you aware of the risks? Learn why fewer than half of Americans understand the safety benefits of pasteurization.

Did you know that pouring a glass of raw milk could be pouring a glass of potential danger? A recent survey by the Annenberg Public Policy Center (APPC) reveals that fewer than half of Americans understand the health risks of raw milk. Only 47% of U.S. adults know raw milk is less safe than pasteurized milk. Realizing that raw milk can make you sick is crucial, while pasteurization reduces the risk of milk-borne illnesses. Each individual’s understanding of this issue is critical, as it empowers them to make informed decisions about their health. The APPC survey, conducted by SSRS, highlights a significant gap in public knowledge, raising serious concerns about food safety education and public health.

Despite the potential health risks associated with consuming raw milk, many Americans remain uninformed about its dangers. A recent survey conducted by the Annenberg Public Policy Center reveals a significant knowledge gap among the public regarding the safety of raw versus pasteurized milk. Below is a detailed breakdown of the survey findings: 

Survey QuestionPercentage
Know that raw milk is less safe than pasteurized milk47%
Incorrectly think pasteurization is not effective at killing bacteria and viruses4%
Not sure whether pasteurization is effective at killing bacteria and viruses20%
Think drinking raw milk is safer9%
Think drinking raw milk is just as safe15%
Unsure whether drinking raw milk is safer or as safe as drinking pasteurized milk30%

“It is important that anyone planning to consume raw milk be aware that doing so can make you sick and that pasteurization reduces the risk of milk-borne illnesses.” — Patrick E. Jamieson, Director of the Annenberg Health and Risk Communication Institute

Unveiling the Truth: Alarming Gaps in Public Awareness of Raw Milk Risks

The APPC survey unveils disturbing gaps in public knowledge about raw milk safety. Only 47% of U.S. adults know raw milk is less safe than pasteurized milk, leaving many misinformed or uncertain about the risks. Notably, 4% incorrectly believe pasteurization doesn’t kill harmful bacteria and viruses, while 20% are unsure of its effectiveness. These findings highlight a crucial misunderstanding that could have profound health implications.

Expert Commentary: Authorities Stress the Imperative of Public Awareness on Raw Milk Risks and Pasteurization Benefits 

Expert commentary highlights the critical need for public awareness of raw milk consumption risks and pasteurization’s benefits. Patrick E. Jamieson emphasizes, “Anyone planning to consume raw milk should be aware that it can make you sick and that pasteurization reduces the risk of milk-borne illnesses.” Kathleen Hall Jamieson concludes, “Pasteurization is crucial for public health as it eliminates harmful pathogens in milk, regardless of political or geographical differences.”

The Hidden Dangers in a Glass: The Health Risks of Consuming Raw Milk 

Raw milk poses significant health risks due to harmful pathogens like CampylobacterE. coli, and Salmonella. These can cause severe illnesses, from food poisoning to serious gastrointestinal conditions. For instance, the Centers for Disease Control and Prevention (CDC) reports that unpasteurized dairy products cause 840 more illnesses and 45 times more hospitalizations than pasteurized versions. The Food and Drug Administration (FDA) echoes these concerns, emphasizing the danger of consuming raw milk, leading to moderate symptoms such as diarrhea and vomiting and critical hospitalizations due to conditions like hemolytic uremic syndrome.

The Advent of HPAI H5N1 in Cow’s Milk: A New Layer of Concern in the Raw Milk Debate

The discovery of avian influenza virus (HPAI) H5N1 in cow’s milk has intensified the raw milk debate. On June 6, 2024, the FDA reported H5N1 in cow’s milk, a virus also widespread among wild birds and infecting poultry and dairy cows in the U.S. This was confirmed in cattle in March 2024, prompting profound implications. 

The CDC reported four U.S. human cases of H5N1 since 2022, with three linked to infected cows, raising severe concerns about raw milk consumption. While conclusive evidence on human transmission through raw milk is pending, a mouse study suggests that the virus in untreated milk can infect susceptible animals, implying potential human risk. 

The NIH echoes these concerns, highlighting the importance of pasteurization, which effectively kills most pathogens. The FDA assures that “evidence continues to indicate that the commercial milk supply [which is pasteurized] is safe.” Nonetheless, the presence of H5N1 in raw milk underscores the critical need for public awareness about pasteurization’s safety benefits and inherent risks.

Navigating the Legal Labyrinth: The Intricate Regulatory Landscape and Rising Market Demand for Raw Milk in the United States

The legal landscape of raw milk sales in the United States is complex. Since 1987, the FDA has banned interstate raw milk sales due to health risks. Yet, 30 states still allow its sale in various forms, such as direct farm purchases, retail sales, or cow-share programs. Despite these risks, demand for raw milk is rising. From late March to mid-May 2024, raw milk sales grew dramatically, increasing by 21% to 65% compared to the previous year. This trend highlights a gap between public awareness of health dangers and consumer behavior driven by misconceptions and anecdotal endorsements. The rise in sales despite the known health risks underscores the need for more effective public health education to bridge this gap and ensure informed consumer choices.

A Clear Divide: Survey Highlights Disparities in Public Understanding of Raw Milk Risks 

Survey data from the Annenberg Public Policy Center highlights troubling gaps in public understanding of raw milk risks. Alarmingly, 54% of respondents either mistakenly believe raw milk is safer (9%), just as safe (15%), or are unsure (30%) about its safety compared to pasteurized milk. Nearly a quarter doubt pasteurization’s effectiveness, with 20% uncertain and 4% incorrectly deeming it ineffective. Demographic differences are stark: older adults (65+) and those with higher education are more likely to correctly recognize pasteurization’s safety benefits. In contrast, 25% of young adults (18-29) wrongly believe pasteurization destroys nutrients, compared to just 5% of those aged 65 and older. 

These findings underscore the urgent need for targeted educational efforts to correct widespread misconceptions and inform the public about the risks of raw milk and the benefits of pasteurization. Tailoring these initiatives to specific demographics could be crucial in bridging knowledge gaps and reducing health risks associated with raw milk consumption. For instance, political affiliation also influences perceptions. Democrats are more likely than Republicans to understand raw milk is less safe than pasteurized milk (57% vs. 37%). Conversely, 23% of Republicans, compared to 8% of Democrats, incorrectly believe pasteurization destroys milk nutrients. Geographic distinctions add another layer; urban dwellers more readily view raw milk as less safe compared to rural residents (49% vs. 32%). However, urban vs. rural residency does not significantly affect beliefs about pasteurization’s nutritional impact. Understanding these societal influences can help to target educational efforts more effectively. 

These findings underscore the urgent need for targeted educational efforts to correct widespread misconceptions and inform the public about the risks of raw milk and the benefits of pasteurization. Tailoring these initiatives to specific demographics could be crucial in bridging knowledge gaps and reducing health risks associated with raw milk consumption. With the proper education and awareness, we can make a significant change in public health.

Nutrient Integrity vs. Safety: Debunking the Myths Surrounding Pasteurization in the Raw Milk Controversy

Among the contentious points in the raw milk debate is the assertion that pasteurization destroys valuable nutrients. Raw milk proponents argue that heat treatment negatively impacts the vitamin and mineral content, rendering it less nutritious. However, scientific evidence refutes these claims. The CDC states that pasteurized milk retains the same nutritional benefits as raw milk, minus the associated health risks. Essential nutrients like calcium, protein, and vitamins are preserved during pasteurization. This process eliminates harmful pathogens, preventing severe foodborne illnesses. The CDC advocates for pasteurized milk as a safer alternative that doesn’t compromise nutritional value, highlighting that the significant reduction in health risks far outweighs the minimal impact on some vitamins.

The Bottom Line

The survey’s findings unmistakably illustrate a significant gap in public awareness regarding the dangers of raw milk consumption. Central to this discussion is the crucial message that the risks associated with raw milk are severe and often misunderstood. The disparity in knowledge is striking, with less than half of Americans recognizing that raw milk is less safe than pasteurized milk. Public education is paramount in bridging these knowledge gaps. Individuals must base their dietary choices on rigorously validated scientific data rather than anecdotal evidence or online misinformation. By fostering a well-informed public, we can help mitigate the health risks associated with consuming raw milk and ensure that everyone makes safer, more informed decisions regarding their dairy products.

Key Takeaways:

  • Fewer than half (47%) of U.S. adults know that drinking raw milk is less safe than drinking pasteurized milk.
  • Nearly a quarter of Americans either incorrectly think pasteurization is not effective at killing bacteria and viruses in milk products (4%) or are unsure about its effectiveness (20%).
  • Unpasteurized dairy products cause significantly more illnesses and hospitalizations than pasteurized products.
  • The FDA has reported the detection of bird flu (HPAI H5N1) in cow’s milk, raising further health concerns.
  • The survey revealed that adults aged 65 and older, those with college education, and Democrats are more likely to understand the benefits of pasteurization.
  • Raw milk sales have been increasing despite the known health risks, with some political leaders advocating for its consumption.
  • ofOver half Americans either believe that raw milk is safer or as safe as pasteurized milk, or are unsure about the relative safety.
  • There is a persistent belief among some Americans that pasteurization destroys nutritional value, despite evidence to the contrary.
  • The survey found significant differences in beliefs about raw milk safety based on political affiliation and living environment (rural vs. urban).

Summary:

A survey by the Annenberg Public Policy Center found that less than half of Americans understand the health risks of raw milk, with only 47% believing it is less safe than pasteurized milk. Raw milk is known to contain harmful pathogens like Campylobacter, E. coli, and Salmonella, which can cause severe illnesses and gastrointestinal conditions. The CDC reports that unpasteurized dairy products cause more illnesses and hospitalizations than pasteurized versions. The FDA and NIH emphasize the importance of pasteurization, while the CDC and FDA assure the commercial milk supply is safe. Despite these risks, demand for raw milk is rising, with sales increasing by 21% to 65% from March to May 2024.

Michigan Provides Financial Aid to Dairy Farmers Battling Avian Flu Crisis

Learn how Michigan is helping dairy farmers affected by avian flu with emergency funds and research. Can these steps control the crisis and ensure safety?

Since March 29, 2024, a staggering 24 operations have tested positive for highly pathogenic avian influenza (HPAI), inflicting a severe blow on Michigan’s dairy producers. The state, recognizing the gravity of the situation, has swiftly mobilized emergency funds to aid affected farmers and advance disease research. Dr. Tim Boring, director of the Michigan Department of Agriculture, underscores the crucial work being done at the intersection of public health and animal welfare.

“Our HPAI-impacted farms have been immensely cooperative in Michigan’s one-health approach to combat this disease,” Boring says.

Michigan is not facing the HPAI epidemic alone. The state is providing $28,000 to up to 20 HPAI-infected farms for comprehensive research and inspections, a strategic move to halt the epidemic. This assistance is further bolstered by existing USDA funding, underscoring the coordinated effort between the state and the dairy industry to aid in recovery and prevent further spread.

HPAI’s Ripple Effect on Michigan’s Agriculture: A Chronological Insight

Since its onset, highly pathogenic avian influenza (HPAI) has left an indelible mark on Michigan’s agriculture. The first case was confirmed on February 22, 2022, at a Kalamazoo County home chicken farm. By the end of 2022, the virus had spread rapidly, leading to the depopulation of 21 chicken flocks, a testament to its virulence and the need for immediate action.

The fight continued, with another seven chicken flocks impacted in 2023. The issue worsened on March 29, 2024, when HPAI was verified at a significant commercial dairy facility in Montcalm County with over 500 cows. This underlined how easily the virus may cross-species, affecting dairy operations and poultry ones.

Eight poultry farms and twenty-three dairy plants have tested positive for HPAI since April 2024. Particularly impacted have been counties like Clinton, Gratiot, and Ionia. Ionia County noted illnesses in one private flock, three commercial hen-laying farms, and five dairy enterprises.

HPAI’s growth in Michigan fits a more significant trend influencing many animal species worldwide, complicating control attempts. Although dairy cows have largely non-fatal rates, there are questions about possible mutations compromising human health.

Emphasizing the need to control HPAI, Michigan’s approach consists of tight cooperation with federal and state authorities. The state’s financing for financial help and research highlights initiatives to lessen the virus’s effects on the agricultural sector and animal welfare.

The Complexity of HPAI’s Impact on Michigan Dairy Farms 

The invasion of HPAI into Michigan’s dairy industries has presented complex problems. Although the virus causes symptoms like fevers, stiff feces, aberrant milk, and lower output, it is less lethal for dairy cows than poultry. These problems compromise the economic stability of the farms and the general state of the herd.

Infected cows are segregated into sick pens and treated with antibiotics and fluids to control the epidemic. This upends routine agricultural operations and requires extra labor and resources.

Milk output is affected. To guarantee safety, milk from cows positive for HPAI is removed from the commercial supply chain, resulting in significant losses and smaller profits for dairy producers.

Emergency Funding to Combat HPAI: Michigan Takes Action

Tim Boring, Director of the Michigan Department of Agriculture, has launched a critical emergency finance project addressing the significant obstacles dairy producers face from highly pathogenic avian influenza (HPAI). Each of the twenty HPAI-infected farms receives up to $28,000 from the state. This helps call on farmers to work with state and federal authorities for extensive epidemiological research and real-time dairy herd analyses. The money allows attempts at farm recovery and promotes studies on the dynamics of the illness. This state-level assistance augments USDA financial aid for dairy farms impacted by HPAI in Michigan.

Federal Collaboration Bolsters Michigan’s Response to HPAI with Ground-Level Interventions 

The USDA’s emergency management and epidemiology specialists have been vital in helping Michigan combat HPAI in concert with government authorities. They allow the Michigan Department of Agriculture and Rural Development (MDARD) to supervise biosecurity policies and guarantee effective depopulation, supporting on-the-ground operations throughout impacted poultry plants.

Tracing and testing within dairy cows, the USDA epidemiology team analyzes real-time data to better grasp the virus’s spread and effect on public and animal health. Their efforts help build focused containment and recovery plans, supporting Michigan’s one-health strategy.

Michigan’s Integrated “One-Health” Response: Bridging Animal and Public Health

Integrating animal and public health issues, Michigan’s response to the HPAI epidemic epitomizes the “one-health” philosophy. For fast testing, tracking, and epidemiological studies, MDARD works with the USDA and other partners. This alliance guarantees public health safety and meets the demands of compromised dairy farmers. Using USDA emergency management teams emphasizes the level of collaboration. It helps to protect human health hazards as well as animal welfare. This strategy demonstrates Michigan’s will to safeguard its agriculture and minimize any risks to public health.

Inter-species Transmission: The Unseen Human Health Risk in HPAI Outbreaks 

Although HPAI mainly affects birds, its potential harm to human health is excellent. Naturally zoonotic, it may go from animals to people. Though its main effect is on poultry and dairy cows, rare human cases—such as those seen in Michigan, where two dairy farmworkers developed HPAI—showcase the importance of alertness even in this regard. These illnesses highlight the need to care for everyone who comes close to sick animals.

The CDC classifies the public risk of HPAI transmission as minimal. The virus cannot readily infect humans or pass between individuals. Still, there is a danger of mutation and higher transmissibility. This emphasizes the need for a thorough “one-health” strategy to track and reduce HPAI risks.

Public health campaigns advise persons regularly exposed to possibly infected animals to have a seasonal flu vaccination. It lowers the likelihood of double infections with human and avian influenza A viruses even if it does not guard against H5N1 bird flu. This approach seeks to minimize effects on public health and support Michigan’s commitment to adequately controlling HPAI outbreaks.

Ensuring the Safety of Our Milk Supply: The Indispensable Role of Pasteurization in Combating HPAI

Amidst the challenges posed by HPAI, the safety of Michigan’s commercial milk supply remains uncompromised. The key lies in the rigorous process of pasteurization, which ensures the elimination of dangerous germs and viruses. These stringent guidelines, upheld by the USDA and MDARD, further enhance these safety measures, instilling confidence in the public health protection measures in place.

Governor’s Emergency Declaration: A Pivotal Step in Protecting Michigan’s Poultry and Dairy Sectors

Tim Boring’s “Determination of Extraordinary Emergency” enhanced Michigan’s defenses of its poultry and cattle sectors on May 1. Building on a federal mandate, this state directive emphasizes the grave danger of HPAI. It demands additional resources to stop its spread. The statement seeks to rapidly contain epidemics, minimizing financial damage to farmers and preserving public health. To strengthen Michigan’s agricultural resilience against future zoonotic threats, it underlines the importance of concerted effort, tight biosecurity, and quick reactions.

The Bottom Line

Highly pathogenic avian influenza (HPAI) invading Michigan’s dairy farms presents a significant threat. The state’s reaction emphasizes the gravity of the matter by including federal cooperation and emergency money. While bolstering dairy producers and safeguarding public health, efforts center on stopping the virus’s spread.

HPAI has seriously rocked Michigan’s dairy sector. Still, the state’s “one-health” approach—combining public health policies with animal rights—aims to address this problem adequately. From separating sick animals to guaranteeing milk safety via pasteurization, Michigan’s steps show a solid structure to control the situation.

Farmers, agencies, and the public must work together and be constantly alert. Regular animal handlers should consider getting seasonal flu shots to reduce their chance of concomitant infections with human and avian influenza viruses.

Being informed is vital. Stay current with the latest from connected agencies like the Michigan Department of Agriculture and Rural Development. Overcoming HPAI and protecting public health and agriculture depend on collective understanding and engagement.

Key Takeaways:

This development marks the third human case in the United States linked to an ongoing multistate outbreak, a worrying scenario where cow-to-person transmission is the prime suspect. Michigan now finds itself at the epicenter of this health concern, with government officials and health experts racing to understand and mitigate the spread of this elusive virus. 

“We’re learning more every day about the epidemiology of this virus and how it spreads.” – Tim Boring, Director of the Michigan Department of Agriculture and Rural Development.

Ensuring Robust Biosecurity Measures Amidst H5N1 Outbreak 

Dr. Natasha Bagdasarian highlighted the critical need for PPE in agricultural settings. “Reiterating the importance of PPE to all workers can significantly reduce virus transmission among farmworkers and their families,” she stated. 

The CDC maintains that H5N1 poses a low risk to the general population but stresses stringent precautions for those handling infected animals. “While the general public is not at significant risk, workers near infected livestock must adhere to our guidelines to prevent further human cases,” said CDC representative Emilio R. Gonzales, M.P.H. 

Biosecurity efforts are practical, but vigilance is essential. “Ongoing assessment and adaptation of biosecurity protocols are crucial. Each confirmed case provides new data to refine these measures,” said Boring. This diligence ensures the dairy supply remains uncompromised and prevents the virus from entering the food chain. 

Vaccine development brings cautious optimism. The production of 4.8 million H5N1 avian flu vaccine doses is a significant step toward minimizing risk to humans and animals. This aligns with global efforts to secure vaccines for at-risk populations, including poultry and dairy workers, veterinarians, and lab technicians. Influenza experts like Cynthia Reinoso Webb, Ph.D., stress that these measures could curb the pandemic threat. 

“We are at a crucial juncture,” notes Dr. Marie K. Kirby, Ph.D. “Investing in preventive strategies protects workers and safeguards public health. Collaboration between government agencies, health departments, and the agricultural industry is pivotal in addressing this evolving challenge.”

Concentrated Outbreaks Highlight Critical Need for Coordinated Response 

As of the latest update, the Centers for Disease Control and Prevention (CDC) has confirmed three human cases of the H5N1 virus in the United States—two in Michigan and one in Texas. This underscores the critical nature of the ongoing outbreak. 

In Michigan, health officials have detected the virus in 23 dairy herds, primarily in the west-central part of the state, marking it as a significant hotspot for H5N1. Texas has identified the virus in 15 dairy herds, reinforcing its status as another critical area of concern. 

Beyond Michigan and Texas, the U.S. Department of Agriculture has confirmed the virus across several other states: 8 herds in New Mexico, 9 in Idaho, 4 in Kansas, 4 in Colorado, 4 in South Dakota, and one in Ohio and North Carolina. This multistate outbreak calls for comprehensive and coordinated response efforts to manage and mitigate further spread.

The Strategic Imperative of Robust Biosecurity

Tim Boring, director of the Michigan Department of Agriculture and Rural Development, highlights the efforts to understand the H5N1 virus’s impact on dairy operations. He stresses the importance of biosecurity measures to mitigate the virus’s spread. “We’re learning more every day about how this virus spreads. It’s manageable for now, but we have concerns about mitigating further spread.” Boring emphasizes that using personal protective equipment (PPE) and stringent screening processes are critical, stating, “These biosecurity systems work; pasteurization works. Screening ensures no infected animals enter the food system.” His comments underscore a dynamic approach to this public health challenge.

Biosecurity practices are vital for controlling H5N1 transmission, especially on dairy and poultry farms. Measures like proper sanitation, controlled access to livestock areas, and regular animal health screenings are essential defenses against this highly pathogenic avian influenza virus. 

However, gaps in biosecurity often stem from the improper use or absence of personal protective equipment (PPE) among farm workers. The recent H5N1 cases among Michigan farm workers underline this vulnerability, highlighting the importance of PPE in minimizing human exposure. Dr. Natasha Bagdasarian, Michigan’s chief medical executive, notes, “Direct exposure to infected livestock poses a risk to humans. PPE is an important tool in preventing spread among individuals who work on dairy and poultry farms.” 

The CDC strongly advocates for using PPE and other precautions for those exposed to potentially infected animals. Implementing these measures protects farmworkers and helps contain the virus, thereby reducing the risk of further outbreaks. Strengthening biosecurity systems alongside diligent PPE use is crucial for safeguarding animal and human health during infectious disease events.

Vigilant PPE Use and Biosecurity Uphold Public Health Safety Amid H5N1 Concerns

The CDC assures that the public health risk posed by H5N1 is currently low but stresses the importance of strict precautions for those in direct contact with infected or potentially infected animals. This is crucial to preventing the virus from spreading more frequently to humans. 

In agriculture, biosecurity measures are vital for containing H5N1. Tim Boring, Director of the Michigan Department of Agriculture and Rural Development, states, “These biosecurity systems work; pasteurization works.” Thorough screening prevents infected animals from entering the food supply chain, safeguarding public health. 

Government and health officials ramp up efforts to provide farm workers with PPE, creating a physical barrier between humans and infected livestock. Dr. Natasha Bagdasarian, Michigan’s chief medical executive, highlights the importance of PPE in preventing viral transmission to humans. 

Proactive vaccine development and stockpiling by the U.S. Department of Health and Human Services are essential strategies. Sustained human exposure to H5N1 could lead to mutations that increase its spread among people. Coordinated efforts in biosecurity, PPE use, and vaccine development are crucial to curbing pandemic threats and ensuring the safety of our food system.

The U.S. Department of Health and Human Services Unveils Ambitious Vaccine Initiative to Combat H5N1

This is part of a broader outbreak affecting dairy farms, with the CDC and state officials working to track and contain its spread. Biosecurity measures and PPE have effectively reduced human exposure, but the public health risks demand a coordinated response. The U.S. Department of Health and Human Services plan to produce millions of vaccine doses is critical in pandemic preparedness. Continued vigilance in biosecurity practices and monitoring is crucial to minimizing the virus’s impact on agriculture and public health.

Key Takeaways:

  • Second Human Case in Michigan: The second human infection of H5N1 in Michigan highlights the virus’s persistent threat among farm workers.
  • Third Overall Case in the U.S.: This case marks the third human infection linked to the current H5N1 outbreak in the United States, with the other cases occurring in Michigan and Texas.
  • Ongoing Multistate Outbreak: The virus has affected dairy herds in nine states, indicating a widespread and complex epidemic.
  • Importance of PPE: Infected workers were not using personal protective equipment (PPE), emphasizing its critical role in preventing the virus spread.
  • Biosecurity Measures: Effective biosecurity practices are essential to containing the virus and preventing its transmission from animals to humans.
  • Vaccine Development: The U.S. Department of Health and Human Services is advancing efforts to produce an H5N1 vaccine, reflecting the high stakes of mitigating this outbreak.

Summary: A second farm worker in Michigan has tested positive for the highly pathogenic avian influenza (HPAI) H5N1 virus, marking the third human case in the United States linked to an ongoing multistate outbreak. The virus poses a low risk to the general population but emphasizes stringent precautions for those handling infected animals. Michigan now finds itself at the epicenter of this health concern, with government officials and health experts racing to understand and mitigate the spread of this elusive virus. Dr. Natasha Bagdasarian highlighted the critical need for personal protective equipment (PPE) in agricultural settings to significantly reduce virus transmission among farmworkers and their families. The Centers for Disease Control and Prevention (CDC) has confirmed three human cases of the H5N1 virus in the United States, two in Michigan and one in Texas. The virus has been detected in 23 dairy herds in Michigan and 15 in Texas. The multistate outbreak calls for comprehensive and coordinated response efforts to manage and mitigate further spread. Biosecurity practices are crucial for controlling H5N1 transmission, particularly on dairy and poultry farms. Strengthening biosecurity systems alongside diligent PPE use is crucial for safeguarding animal and human health during infectious disease events.
