California is experiencing a rise in bird flu cases, with six confirmed human infections and five suspected cases among dairy workers in the Central Valley. 

The state’s Department of Food and Agriculture has confirmed bird flu outbreaks in over 100 dairies, which comprise less than 10% of the state’s dairy cow population. However, the virus has not shown signs of human-to-human transmission, with all infected workers contracting the virus through prolonged contact with infected cattle. Symptoms in humans have been mild, including flu-like symptoms and pink eye, and all affected individuals have recovered without hospitalization.

State health officials emphasize that the virus is not evolving in ways that could increase the risk of spreading among humans. Preventive measures are underway, including the distribution of over 2 million pieces of personal protective equipment to dairy workers, particularly in Tulare County. Officials continue to educate and protect workers while reassuring the public that pasteurized milk remains safe to consume.

Milk from infected cows is kept out of the public supply, and officials stress the importance of avoiding raw milk. Pasteurization effectively inactivates the virus, ensuring that dairy products are safe for public consumption. 

Despite the ongoing outbreak, the overall risk to the public remains low, and efforts are focused on preventing further spread and protecting workers in the dairy industry.
