State and federal agriculture officials are looking into a case of bovine tuberculosis from Douglas County.
But the Colorado Department of Agriculture insists that the affected bull was isolated from the processing line at a plant in San Angelo, Texas -- and that no part of the animal got into the food chain.
The illness was revealed through lesions in the bulls' lungs during a routine carcass inspection.
About 660 head of cattle have been quarantined to prevent possible spread of the bovine T-B.
State officials say Colorado will not lose its status as a "T-B Accredited Free State" unless a second infected animal is found somewhere else.
The C-D-A says it's rare for the illness to be spread to humans.
Officials, though, are working with the state Department of Public Health to ensure safety.
