The USDA confirmed a case of Bovine Spongiform Encephalopathy (BSE) in a California dairy cow last week, and now more details have emerged to paint a clearer picture of the fourth U.S. case of BSE.

According to the USDA’s Animal and Plant Health Inspection Service (APHIS), the cow at the center of the case was an elderly cow – 10 years and 7 months old – from a dairy farm in Tulare County, Calif. The animal was humanely euthanized after developing lameness and becoming recumbent.

After being euthanized, the cow’s carcass was taken to a rendering plant operated by Baker Commodities in Hanford, Calif., according to a Reuters report. The carcass was then tested as part of targeted BSE surveillance at rendering facilities.

The USDA reported that the carcass will be destroyed, and reiterated that the animal was at no point present for slaughter for human consumption. It did not enter food supply channels and never presented any risk to human health. Here is a summary of what you need to know about this latest case of BSE.

The epidemiological investigation is expected to continue, and the USDA will provide additional information as it becomes available.
