Two beef cattle herds were quarantined and whole herd tests conducted after a neighboring operation tested positive for bovine TB in July. Both operations have cattle on pastureland that borders the operation of Roger Skime, Wannaska.
Skime agreed to depopulate his 1,020 head of black Angus-Tarentaise crosses and registered Tarentaises so the state could retain its TB-free status.
Four animals tested suspect for bovine TB in late August. Tissue samples were submitted to the National Veterinary Services Laboratory in Ames, Iowa, where a diagnosis of bovine TB was confirmed. With these fenceline contact herds, Minnesota has detected bovine TB in three beef herds in Roseau County.
USDA officials are working on the details of depopulating these infected herds with support and cooperation of the herd owners. State and federal officials have already begun tracking animal movements in to and out of these operations. The newly detected herds are smaller operations with minimal animal movement.
Minnesota Board of Animal Health Executive Director and State Veterinarian Dr. Bill Hartmann said the Board has finished tracking cattle movements into and out of the first TB infected herd.
â€œIf bovine TB is out there, it is our job at the Minnesota Board of Animal Health to find it and eliminate it,â€ Hartmann says. â€œAs a result of the initial investigation, there are 19 Minnesota herds under quarantine in Beltrami, Goodhue, Polk, Marshall, and Roseau Counties. Five herds have completed the required testing and been removed from quarantine.â€
Minnesotaâ€™s last known TB case was in 1971.
