Bovine Tuberculosis Found in South Dakota Cattle Herd

Jan 31, 2025

By Krystal Miga

The state veterinarian says bovine tuberculosis, or TB, has been confirmed in a cow herd in Kingsbury County.

Dr. Beth Thompson said the infected herd was identified through traceback efforts on a Hamlin County feedlot steer.

Meat inspectors initially discovered the infected steer during routine inspections at a Wisconsin packing plant in late October.

Thompson said they’re working closely with the herd owner, USDA and state Animal Industry Board to trace other infected animals and protect the health of the state’s cattle industry.

Officials said Bovine TB is not currently a threat to food safety in the U.S, due to milk pasteurization and comprehensive meat inspection programs.

Video: How Data Predicts Swine Outbreaks - Swaminathan Jayaraman

In this episode of The Swine it Podcast Show Canada, Swaminathan Jayaraman, Research Assistant and PhD Candidate at Iowa State University College of Veterinary Medicine, explains how integrated data systems can improve disease surveillance in swine production. He discusses combining diagnostics, animal movement data, production records, and spatial analytics to identify risks earlier and support proactive decision-making for PRRS, PED, and swine influenza. Listen now on all major platforms!

"Disease surveillance remains largely reactive because outbreaks are often confirmed only after transmission has already occurred across multiple connected production sites."

Meet the guest: Swaminathan Jayaraman / swamjay is a Graduate Research Assistant at Iowa State University College of Veterinary Medicine. With academic training in management information systems and engineering, he focuses on integrating diagnostic, production, and movement data to improve disease surveillance and decision support in swine production systems.
