Viral fragments of bird flu have been detected in milk samples from US grocery stores. This has indicated a wider spread of the avian flu virus among dairy herds than previously known. While this finding doesn't necessarily pose a direct threat to human health due to pasteurization, which typically renders pathogens harmless, It does raise concerns about the virus's prevalence after a case of avian flu was reported in a Texas farmworker in recent weeks. The FDA said some of the samples collected have “indicated the presence” of the bird flu virus based on testing. However, the agency’s statement said that finding the virus “does not mean that the sample contains an intact, infectious pathogen. Officials maintain that the commercial milk supply remains safe, emphasizing the effectiveness of pasteurization. However, ongoing surveillance is crucial, as the virus has recently infected more than two dozen livestock herds across eight states.
