Episode 344 - Salmonella Dublin: The Hidden Threat in Dairy-Beef Systems - UMN Extension's The Moos Room

The Moos Room

Hosted by members of the University of Minnesota Extension Beef and Dairy Teams, The Moos Room discusses relevant topics to help beef and dairy producers be more successful.

This episode highlights new research on Salmonella Dublin in dairy-beef systems and what it means for calf health and farm management.  The disease is a major threat to young calves, causing severe illness and high mortality, while often spreading silently through carrier animals and contaminated environments. New PCR testing shows the pathogen is far more common than traditional methods suggest. Key risk factors include frequent introduction of new calves, mixing animals post-weaning, and human movement (boots, equipment) spreading contamination between areas. Bottom line: Salmonella Dublin isn’t random—it reflects management. Strong biosecurity, better calf flow, delayed weaning, and improved monitoring are critical to reducing risk.
