Greg uncovers the unseen world of microbes that travel across nineteen touches, the hidden dangers of dirty rags and poorly designed sinks, and how everyday cleaning practices can actually make pathogens stronger. A sharp, eye-opening conversation that shows how EHOs and frontline workers can make an enormous impact by understanding the invisible world right at our fingertips.
