October 23, 2024: H5N1 Bird Flu Confirmed in One Hundred Thirty-Four Dairies in California
SACRAMENTO, CA — Following an investigation by the California Department of Food and Agriculture (CDFA) and rapid disease detection by California Animal Health and Food Safety Laboratory System (CAHFS), the U.S. Department of Agriculture’s (USDA) National Veterinary Services Laboratories (NVSL) has confirmed H5N1 Bird Flu in one hundred thirty-four (134) dairies in Central California. CDFA has implemented a surveillance strategy with the goal of finding affected farms as early as possible. Early detection provides the opportunity to work with farms to quickly implement enhanced biosecurity, cow care, and employee protection.
Bird Flu in Humans
As of October 23, 2024, CDPH has confirmed fifteen (15) human cases of bird flu in California. All individuals had contact with animals at different farms and all have experienced mild symptoms, including eye redness or discharge (conjunctivitis). None of the individuals have been hospitalized. While the risk to the general public remains low, additional human cases of bird flu are expected to be identified and confirmed in California among individuals who have contact with infected dairy cattle. CDPH recommends that personal protective equipment (PPE), such as eye protection (face shields or safety goggles), respirators (N95 masks), and gloves be worn by anyone working with animals or materials that are infected or potentially infected with the bird flu virus. Wearing PPE helps prevent infection. Please see CDPH’s Worker Protection from Bird Flu for full PPE guidance. For the latest updates from CDPH, visit Bird Flu (ca.gov).
