Bovine TB detected on Tulare County dairy 

California and federal animal health officials have confirmed the detection of bovine tuberculosis (TB) in a dairy herd in Tulare County. Officials are working closely with the dairy farmer and his veterinarian to implement control strategies to eradicate the disease.

The diagnosis of TB was made after a suspicious mass was detected in a cow during routine slaughter inspection. California Department of Food and Agriculture (CDFA) veterinarians, in coordination with their counterparts at USDA, began testing herds that may have come into contact with the diagnosed cow, and that work led to the detection of TB in the Tulare County herd. The investigation into the possible spread of this gradually debilitating disease is ongoing. California also continues to monitor a dairy herd in San Bernardino County following a bovine TB detection there in 2011.
