The Science of Handwashing: Removing Transient Bacteria vs. Managing Resident Flora

Daily handwashing effectively removes dirt and transient bacteria picked up from the environment. However, it cannot eliminate the resident bacteria that naturally live on our hands.

This article explores the microbiological principles behind handwashing, highlighting its limitations and the implications for food safety.
