It was spurred by a bull that originated in Colorado testing positive for TB at a processing plant in San Antonio. The investigation includes quarantining more than 600 animals while the tests are being conducted. Some believe it could take up to two weeks to get results back from those tests. This is the first link to bovine tuberculosis for the state in more than 30 years.

Leaders with the Colorado Cattlemen's Association say an outbreak of the disease affecting other ranches is highly unlikely, but the possibility of more animals testing positive for TB is out there.

"I wouldn't say it's likely or unlikely; it is possible and that's the reason the state vet has quarantined the animals," says the CCA's executive vice president Terry Fankhauser.

At the turn of the 20th century, an outbreak would have been devastating but now there are treatments for the disease. Even if more cattle are determined to be sick, Colorado Cattlemen's Association leaders say it won't be a threat to the food chain.
