Raw cheese made with milk from dairy cattle infected with bird flu can harbor infectious virus for months and may be a risk to public health, according to a new study from researchers at Cornell University that was funded by the US Food and Drug Administration.

Although the Food and Drug Administration (FDA) located H5N1 bird flu virus in samples of raw, or unpasteurized, milk in tests in four states in April 2024, and bird flu has been detected in commercially sold raw milk,

Scientists are sounding alarms about a genetic mutation that was recently identified in four dairy cow herds, nearly one year after H5N1 bird flu was first reported in Texas dairy cattle.

Scientists already discovered that raw milk can harbor the infectious H5N1 bird flu virus, but now there’s a new study on its capabilities that has health officials concerned.

Prior exposures to specific types of seasonal influenza viruses promote cross-reactive immunity against the H5N1 avian influenza virus, according to new research from the Perelman School of Medicine at the University of Pennsylvania.
