Northern Michigan beef herd bovine TB positive

A medium-sized beef herd in Northern Michigan has been confirmed positive for bovine tuberculosis.

State veterinarian Nora Wineland says the National Veterinary Services Lab confirmed a herd in Alcona County positive for the disease this week.  Alcona County is in a Modified Accredited Zone where herds are routinely tested for bovine TB.

The herd will be quarantined while additional testing is done to help determine the strain of infection as well as trace investigations to identify any potential additional cases.  This is the 77th confirmed herd and first of 2020 following three positive herds last year in Michigan.
