The recent discovery of bird flu virus in cow milk has sparked concerns about potential risks to human health. Avian influenza viruses, which include the strains responsible for bird flu, are known to infect mammals, including humans, albeit infrequently. While the likelihood of human infection from consuming milk contaminated with the bird flu virus is generally considered low, it does raise important questions about potential impacts.
Will Bird Flu Virus Found In Cow Milk Impact Humans?
We spoke to our expert Dr Shweta Jaiswal, Senior Dietician - Sharda Hospital to shed some light on the same. Here is what she shared with us.
1. Transmission to Humans
The primary concern is whether the bird flu virus present in cow milk can infect humans. If so, it could lead to cases of avian influenza in individuals who consume contaminated milk or milk products. The severity of illness can vary widely, from mild flu-like symptoms to severe respiratory illness and even death in severe cases.
2. Public Health Response
The discovery of bird flu virus in the milk supply would likely trigger a swift response from public health authorities. Measures such as recalling contaminated milk products, implementing stricter monitoring and testing of dairy farms and processing facilities, and educating the public about safe food handling practices would be crucial to prevent further spread.

3. Economic Impact
Any outbreak of avian influenza, whether in birds or potentially in humans, can have significant economic consequences. Losses in the dairy industry due to decreased consumer confidence, trade restrictions by other countries, and costs associated with containment and control measures could all occur.
4. Preventive Measures
To mitigate the risk of human infection, strict preventive measures need to be implemented. This includes maintaining biosecurity measures on farms, conducting regular surveillance for avian influenza viruses, and ensuring proper hygiene and sanitation practices during milk production and processing.

5. Health Monitoring
Health authorities may conduct enhanced surveillance for cases of avian influenza-like illness in humans, especially in areas where contaminated milk products have been distributed. Early detection and prompt treatment of any human cases are essential to prevent further spread.
A Final Word
While the discovery of bird flu virus in cow milk is concerning, the actual impact on human health depends on several factors. These include the characteristics of the virus, the extent of contamination, and the effectiveness of public health and preventive measures implemented in response. Vigilance, prompt action, and effective communication are crucial to managing and minimising any potential risks to human health.
