California recalls raw milk products after bird flu findings

In December 2024, the U.S. Department of Agriculture (USDA) implemented a federal order that requires raw or unpasteurized milk from dairy farms and processors across the United States to be tested for the H5N1 bird flu virus. This order follows the detection of the virus in dairy cattle for the first time in March 2024, leading to over 700 infected herds in 15 states, with California being the hardest hit as nearly 500 of the infected herds are located there. The recent mandate aims to contain the virus and prevent further transmission among livestock, particularly considering the rising number of human infections associated with close contact to infected animals, especially dairy and poultry workers. The immediate testing began on December 16, 2024, and will first be rolled out in key states such as California, Michigan, and Colorado. Health officials have stated the risk to the general public remains low, but they continue to warn against the consumption of raw milk, which has been linked to other foodborne illnesses. Experts stress the importance of biosecurity measures and that effective monitoring will aid in controlling the outbreak. The challenges remain present as many dairy farmers have shown reluctance toward testing due to fear of economic repercussions and the potential fallout within the dairy industry. Furthermore, health departments have issued recalls for certain raw milk products after the detection of the virus. Overall, the USDA's initiative reflects an urgent response to ensure both public health safety and the stability of the dairy supply chain.
