A severe outbreak of bird flu, caused by the H5N1 strain, is spreading among humans, dairy cows, and poultry in the United States. The outbreak started in February 2022 and has since affected 125 million poultry and spread to 1,168 farms, including 792 backyard farms and 592 commercial farms. The human infections, totaling 61, are largely due to contact with poultry, with some cases linked to dairy cows. The source of the infection in dairy cows is still unknown, with speculations pointing to poultry manure in feed or direct contact with the virus.

Health authorities have recommended against consuming raw milk or dairy products since the first case in March 2024, while pasteurized products are deemed safe.
