The County of Santa Clara Public Health Department has been testing raw milk from local retail stores as part of the county's monitoring program for H5N1 bird flu. On November 21, the county's Public Health Laboratory identified H5 in samples of raw milk produced by Raw Farms LLC, purchased at a retail outlet. The County immediately notified the California Department of Public Health. The raw milk was voluntarily recalled by the company and the state has advised the public to not consume the contaminated raw milk.
