Think your milkroom is clean? Think again. In this episode of Hoofnotes, we dive into the microscopic world of biofilms, sticky, invisible communities of bacteria that love to set up shop inside milk lines, inflations, and buckets. These aren’t just harmless slime layers. Biofilms can harbor dangerous pathogens, resist standard cleaning routines, and quietly compromise both milk quality and herd health.

We’ll break down the science behind how biofilms form, why they’re so hard to kill, and what the latest research says about cleaning protocols that actually work. From the role of Clean-in-Place (CIP) systems to the chemistry of disinfectants and the dangers of “just rinsing it,” this episode arms you with the know-how to fight back.

Whether you're hand milking two goats or machine milking twenty-two, when it comes to biofilms, it's not just about milk safety, sloppy sanitation can lead to sick goats, mastitis outbreaks, and costly setbacks.
