Fragments of the virus causing bird flu, H5N1, have been discovered in about one in five pasteurized milk samples throughout the US, as reported by the US Food and Drug Administration. However, subsequent testing has revealed that the virus is non-infectious, allaying fears of contamination.

The FDA emphasized that despite the presence of the virus in some pasteurized milk samples, the milk supply remains safe for consumption. Pasteurization, a standard process for commercial milk production, is designed to eliminate harmful bacteria and viruses, including the bird flu virus.

This recent discovery is significant as prior reports of bird flu in dairy cows were limited to unpasteurized products, highlighting a potential wider spread of the virus within cattle populations. While the current risk to human health is deemed low, concerns have been raised by experts regarding the transparency of information provided by US health agencies on the issue.

Virologists and infectious disease specialists have pointed out the need for greater transparency and urgency in sharing data related to bird flu in farm animals and milk samples. The lack of information could hinder effective response measures to prevent the spread of the disease.

In response to these concerns, the FDA has pledged to continue monitoring retail milk products and sharing findings with the public. The agency’s commitment to ongoing assessment aims to ensure the safety of milk products available to consumers.

As for raw milk, which has not undergone pasteurization, individuals who prefer this unprocessed option for perceived wellness benefits may be at risk. While raw milk has gained popularity among certain consumers seeking natural or holistic food choices, the recent findings underscore the importance of proper milk processing to safeguard against potential health risks.

Consumers are advised to adhere to recommended food safety practices and rely on pasteurized milk products to mitigate the spread of infections through dairy consumption. Continued vigilance and transparency in monitoring milk supplies are essential to safeguarding public health and preventing the spread of infectious diseases.
