The bird flu virus has been detected in a batch of raw milk from a dairy farm in Central California, according to the California Department of Public Health. The milk, produced and packaged by Raw Farm in Fresno County, has been voluntarily recalled by the company. The affected batch has a lot code of 20241109 and a "Best By" date of November 27, 2024. Consumers are advised to return any remaining product to the point of purchase. No illnesses have been reported in connection with the tainted milk.
The sample was tested by the Santa Clara County Public Health laboratory as part of the state's ongoing efforts to monitor for bird flu. Since the first detections of bird flu in the state's dairy cows in August, raw milk from farms has been tested weekly by the California Department of Food and Agriculture.
The discovery of the virus in raw milk comes just days after a child in Alameda County tested positive for the bird flu virus despite not having any known contact with an infected animal. The case is considered a “possible” case until confirmed by the Centers for Disease Control and Prevention.
Bird flu, or avian influenza, is primarily transmitted among birds. The virus can cause a range of symptoms in humans, including headache, eye irritation, fever, and chills. In severe cases, it can be fatal. Federal health officials advise against drinking raw milk, as it can carry harmful bacteria, including E. coli, salmonella, listeria, and the bird flu virus. Pasteurized milk, which is heated to kill harmful germs, is recommended.
