In a recent revelation, the US Food and Drug Administration (FDA) disclosed the detection of viral particles of H5N1 avian influenza in milk purchased from grocery stores. Despite this finding, the FDA maintains its stance that pasteurized dairy products remain safe for consumption.
The agency attributes the detection of viral particles to highly sensitive laboratory tests, suggesting that these remnants are likely remnants of viruses eradicated during the pasteurization process. While the FDA reassures the public that the likelihood of these particles infecting individuals is low, it is conducting further tests to ensure complete certainty.
Utilizing egg inoculation tests, considered a gold standard for assessing a virus’s viability and infectivity, the FDA is rigorously examining multiple studies to corroborate its findings and ensure consumer safety.
Dr. Eric Topol, founder of the Scripps Research Translational Institute, underscores the significance of this discovery, suggesting that the outbreak may be more widespread than previously believed. While the FDA’s assurances regarding dairy safety are noted, concerns persist amid ongoing USDA mishandling and insufficient information sharing.
The USDA’s confirmation of highly pathogenic avian influenza in dairy cows, coupled with its slow dissemination of information, has raised alarm among scientists and the public alike. The infected cows exhibited unusual symptoms, including decreased appetite and altered milk consistency, indicating direct mammary gland infection.
As researchers delve into the origins and transmission of the virus among cattle, concerns arise over potential spillover to other livestock, particularly pigs. With pigs serving as efficient hosts for flu viruses, the prospect of H5N1 adapting to human receptors poses a significant risk.
Amid these challenges, the FDA emphasizes the importance of pasteurization in eliminating pathogens, maintaining that 99% of milk in the commercial supply adheres to stringent safety standards. However, ongoing testing and collaboration with the CDC’s food safety group underscore the agency’s commitment to vigilance.
While the current outbreak underscores the need for enhanced surveillance and reporting mechanisms, efforts remain focused on mitigating risks and ensuring public health and safety.
