Rapid Risk Assessment: Risk to UK consumers from Highly Pathogenic Avian Influenza (HPAI) H5N1 B3.13 in US dairy products
In March 2024, the US Centers for Disease Control and Prevention (CDC) and Food and Drug Administration (FDA) issued a press release confirming that the RNA of a strain of highly pathogenic avian influenza (HPAI) had been detected in dairy cattle herds that had been displaying milk drop and other clinical signs. In April 2024 the FDA confirmed that infectious virus (sometimes called bird flu) was present in raw milk, and a university research group claimed that RNA was detectable in pasteurised milk on retail sale.
