Public hearing for the proposed bovine TB testing area in Arenac, Iosco, and Ogemaw counties
Public Hearing for Arenac, Iosco, and Ogemaw Counties
MDARD is proposing expanded testing requirements due to the detection of bovine TB in additional cattle herds from Iosco County last month. These supplementary testing efforts are required as part of Michigan’s bovine TB management plan that allows for split-state status and determines the extent of disease movement outside the four-county Modified Accredited Zone. Since Arenac, Iosco, and Ogemaw counties are not within Michigan’s existing bovine TB testing area, Public Act 466 of 1988 authorizes MDARD to implement an order for testing animals for bovine TB and other reportable diseases.
The proposed order would require all cattle and bison herds located in designated township sections of Arenac, Iosco, and Ogemaw counties to be tested for bovine TB by July 31, 2027. This testing would include all cattle and bison 12 months of age or older as well as cattle and bison of any age that were not born on the farm. Producers known to be within the proposed testing area will receive a letter providing more details.
Interested individuals may comment on the proposed order at an upcoming public hearing or via e-mail or U.S. Mail.
Written comments regarding the proposed order must be received by 5 p.m. on Friday, November 13, 2026.
