Understanding the Threat of Bird Flu

Since 2022, a new, highly pathogenic strain of H5N1 influenza or “bird flu” has spread worldwide. In the U.S. it has affected over 100 million birds and for the first time, spread into dairy cows and a small, but growing, number of people. At UC Davis, experts in One Health — an approach that considers the health of people, animals and the environment together — are on high alert.

These tests are handled by the California Animal Health and Food Safety Laboratory System – the backbone of California's warning system that helps to protect the health of California's livestock and, thereby, the lives of Californians.

How Bird Flu Virus Fragments Get into Milk Sold in Stores, and What the Spread of H5N1 in Cows Means for the Dairy Industry and Milk Drinkers

The discovery of fragments of avian flu virus in milk sold in U.S. stores, including in about 20% of samples in initial testing across the country, suggests that the H5N1 virus may be more widespread in dairy cattle than previously realized.
