Abstract The recent outbreak of highly pathogenic avian influenza (HPAI) in dairy cows has created public health concerns about the potential of consumers being exposed to live virus from commercial dairy products. Previous studies support that pasteurization effectively inactivates avian influenza in milk and an earlier retail milk survey showed viral RNA, but no live virus could be detected in the dairy products tested. Because of the variety of products and processing methods in which milk is used, additional product testing was conducted to determine if HPAI viral RNA could be detected in retail dairy samples, and for positive samples by quantitative real-time RT-PCR (qRT-PCR) further testing for the presence of live virus. Revised protocols were developed to extract RNA from solid dairy products including cheese and butter . The solid dairy product was mechanically liquified with garnet and zirconium beads in a bead beater diluted 1–4 with BHI media. This preprocessing step was su...

Abstract In 2024, the highly pathogenic avian influenza A H5N1 caused outbreaks in wild birds, poultry, cows, and other mammals in the United States with 61 human cases also reported by the CDC. Detection of influenza A H5 RNA in wastewater has been previously reported in sewersheds in Texas and North Carolina with nearby impacted dairy herds following the emergence of H5N1 in dairy cows. Here, we conduct retrospective testing of total influenza A and H5 hemagglutinin genes in wastewater as well presenting and applying new assays for detection of H1 and H3 genes across a respiratory virus season in an urban California sewershed from September 2023-May 2024. Total influenza A, H1, and H3 were regularly detected, while H5 was first detected in March . We developed a model that uses Monte Carlo simulations and previously published parameters to estimate numbers of infected people, poultry, wild birds, or liters of H5-contaminated milk required to result in measured H5 concentrations in wa...

 {Excerpt} (Xinhua) 13:20, December 17, 2024 LOS ANGELES, Dec. 16 (Xinhua) -- The U.S. state of California has recalled raw milk produced and packaged by Valley Milk Simply Bottled , a local dairy company based in Stanislaus County, due to detection of bird flu virus . The recall order came following the detection of Influenza-A H5N1 (bird flu) virus in samples taken from a raw milk bulk tank at the Valley Milk Simply Bottled dairy farm , said the California Department of Food and Agriculture (CDFA) in a release. The order applies to all "Valley Milk Simply Bottled Raw Cow Milk" and "DESI Milk Raw Cow Milk" distributed in quart, half-gallon, and one-gallon plastic jugs with a code date marked on the container of DEC 23 2024 through DEC 30 2024. CDFA urged consumers not to consume any product remaining in their refrigerators. No illnesses have been reported in the state yet. (...)
