New research using monkeys has revealed critical insights into the dangers of consuming raw milk contaminated with the H5N1 avian flu virus. While ingesting the virus can lead to infection, the symptoms appear to be significantly milder compared to exposure through the respiratory system. These findings, published in the journal Nature, emphasize the need to understand how different transmission routes influence the severity of the disease.
Scientists from the National Institute of Allergy and Infectious diseases conducted a study using cynomolgus macaques to investigate how the H5N1 virus, especially the 2.3.4.4b strain, behaves when introduced through various pathways. this specific strain has been spreading among U.S. dairy cattle since spring 2024 and has infected 40 dairy workers across four states, though most cases have been mild. The exact method of transmission from cows to humans remains unclear, prompting researchers to use macaques as a model for human infection.
In the study, 18 macaques were exposed to the virus through three different methods: intranasally (to mimic upper respiratory infection), intratracheally (to simulate lower respiratory infection), and orogastrically (to replicate the consumption of contaminated milk). After 14 days, the results were striking. Lower respiratory exposure caused severe pneumonia and systemic infection, while upper respiratory exposure led to mild-to-moderate pneumonia. Though, the macaques exposed through the mouth or stomach showed limited infection and no signs of illness.

All the monkeys showed evidence of oral and limited nasal shedding of the virus, but those exposed through the nose and windpipe had higher and more prolonged shedding. The researchers noted,”Our study shows that lower and upper respiratory tract infection can lead to systemic virus replication,virus shedding,and pneumonia with varying degrees of disease outcome. in contrast, orogastric exposure led to virus infection, reduced virus shedding, and subclinical disease.”
While these findings provide valuable insights, the researchers caution that the macaque model is not a perfect depiction of human infection. “To what extent it recapitulates human infection remains, as yet, unclear,” they wrote. This uncertainty highlights the need for further research to fully understand the risks associated with consuming raw milk during an H5N1 outbreak.
For now, health experts continue to advise against drinking raw milk, especially during an outbreak. The potential risks, even if milder, are significant enough to warrant caution. As research continues, understanding the nuances of virus transmission will be crucial in developing effective public health strategies.
understanding the Risks of Raw Milk: an Expert’s Perspective
By [Yoru Name], News editor
In recent years, raw milk has become a hot topic, with advocates praising its natural qualities and critics warning of its dangers. To better understand the risks and realities of raw milk consumption, we sat down with Dr. Emily Carter, a leading food safety expert with over 15 years of experience in microbiology and public health.
What Is Raw Milk?
archyde: Dr. Carter, let’s start with the basics. What exactly is raw milk, and how does it differ from the milk we typically buy at the store?
Dr. Carter: raw milk is milk that hasn’t undergone pasteurization, a process that involves heating the milk to kill harmful bacteria. The milk you find in stores is almost always pasteurized, making it safer for consumption. Raw milk, conversely, comes straight from the animal without this critical safety step.
Are There Health Benefits to Raw Milk?
Archyde: Some people claim that raw milk has health benefits,such as containing more nutrients and beneficial bacteria. What’s your take on these claims?
Dr. Carter: While some believe raw milk contains more nutrients, enzymes, and beneficial bacteria, these claims lack strong scientific support. The risks associated with raw milk far outweigh any potential benefits.Raw milk can harbor hazardous pathogens like E. coli, salmonella, and Listeria, which can cause severe illness, particularly in children, pregnant women, and individuals with weakened immune systems.
What Are the Specific Risks of Consuming raw Milk?
Archyde: Can you elaborate on the specific dangers of consuming raw milk?
Dr. Carter: absolutely. Raw milk can be a breeding ground for harmful bacteria, viruses, and parasites. These pathogens can lead to foodborne illnesses, with symptoms ranging from mild stomach discomfort to severe conditions like kidney failure or even death. For example, Listeria in raw milk can cause miscarriages in pregnant women, and E. coli can lead to hemolytic uremic syndrome in children.
Why Has Raw Milk Gained Popularity?
Archyde: Given these serious risks, why do you think raw milk has gained popularity?
Dr. Carter: I believe it’s partly due to a growing interest in natural and unprocessed foods. People are drawn to the idea of consuming food in its purest form. However, it’s crucial to understand that raw milk carries significant health risks, especially in light of recent outbreaks of avian flu. Pasteurization,which involves heating milk to kill harmful pathogens,remains the safest way to ensure milk is free from viruses like H5N1.
Conclusion
As scientists continue to study the complexities of foodborne pathogens,staying informed and cautious is the best way to protect yourself and your family. While raw milk may seem appealing to some, the potential dangers make it a risky choice.always prioritize safety by choosing pasteurized milk and staying updated on food safety guidelines.
