The Minnesota Board of Animal Health announced Tuesday that a Roseau County beef cattle herd has tested positive for bovine tuberculosis. The newly detected Roseau herd tested negative in 2005 and 2006, but during a third, follow-up round of testing in November, one animal tested suspect for bovine TB. Tissue samples were collected and submitted to the National Veterinary Services Laboratory in Ames, Iowa, where a diagnosis of bovine TB was confirmed late last week. Minnesota has now detected bovine TB in nine beef herds.
At this time, Minnesota's Modified Accredited Advanced TB status will remain unchanged. Minnesota Board of Animal Health executive director and state veterinarian Dr. Bill Hartmann said work will continue unabated to return the state to TB-free status. However, the discovery of any additional herds could result in the downgrading of Minnesota's status.
