raw milk

California state agriculture officials ordered the recall of raw milk from a dairy farm in the Central Valley after tests found bird flu virus in a sample from the farm's bulk tank. The state Department of Food and Agriculture warned against consumption of milk from Valley Milk Simply Bottled on the grounds that it "may lead to infection with this rare, emerging flu virus." No illnesses were reported.

While there has been no sign of person-to-person spread of bird flu, researchers said on Thursday that a single mutation in the H5N1 avian influenza virus could enhance the virus’ ability to attach to human cells. That could potentially increase the possibility of transmission among humans, said the study, led by a team of scientists at the Scripps Research Institute.

A Fresno dairy recalled all of its unpasteurized whole milk and cream products following “multiple bird flu detections in the company’s milk and dairy in the past week,” said the California Department of Public Health. Meanwhile, on Wednesday, the Centers for Disease Control confirmed the 32nd human case of bird flu in the state.

Public health officials in California's Silicon Valley said tests found the bird flu virus in a container of raw milk purchased at a local store and warned consumers on Sunday not to consume the milk. The supplier, Raw Farm, of Fresno County, issued a recall of the batch of milk that was involved.
