Milk processed in big dairy-producing states like California, New York, and Wisconsin were free of any signs of H5N1, at least when the samples were collected. But in some states with known outbreaks in dairy cattle — like Kansas and Texas — half or more of milk samples tested positive for genetic remnants of H5N1. It also showed up at high rates in states without reported cases, including Oklahoma and Kentucky. Some scientists have said the prevalence of the virus in the commercial milk supply is evidence the virus is more widespread than official numbers indicate. But it’s hard to read more into the latest analysis, which represents a snapshot in time and doesn’t say where the milk was produced. Meanwhile, Helen Branswell reports that scientists have managed to generate a full genetic sequence of H5N1 virus from milk. As dairy farmers remain reluctant to allow testing of their cattle, the scientists suggest the development means commercially purchased milk could be used to monitor the outbreak and to check for changes in the virus over time.

Store-bought milk could be another way to track the bird flu outbreak in cows Helen Branswell By Helen Branswell May 21, 2024 https://www.statnews.com/2024/05/21/bird-flu-virus-spread-scientists-monitor-h5n1-in-store-bought-milk/?utm_campaign=morning_rounds&utm_medium=email&_hsenc=p2ANqtz-_n-0RcN1T66N-2sOjPcrgN0AUUgxvjC2Kjci94KqvEZr3kgqTsBgoOTC9IVtKqb1NAFMxUjSayBErPmBTQv9rviDHoCw&_hsmi=307943857&utm_content=307943857&utm_source=hs_email Early tests of H5N1 prevalence in milk suggest U.S. bird flu outbreak in cows is widespread Megan Molteni By Megan Molteni April 25, 2024 https://www.statnews.com/2024/04/25/h5n1-bird-flu-cows-outbreak-likely-widespread/?utm_campaign=morning_rounds&utm_medium=email&_hsenc=p2ANqtz-_l7kQ1oQTZEbumHvhuuaR8VnJtmSZTIVGw_d-mPP9RGlCJ626c_708Ys7i2mprBpRX1SE-dJCnI5i--rX6hV-pwPnQ2w&_hsmi=307943857&utm_content=307943857&utm_source=hs_email
