Study claims hand dryers blast fecal bacteria

The video discusses a study on bacteria found in hand dryers across six bathrooms in a medical school building. The research, published in environmental microbiology, identified harmless lab bacteria and Staphylococcus aureus, which can cause infections. The study suggests that bacteria may travel through the air from labs. Tests on hand dryers with HEPA filters showed that 25% of bacteria remained, indicating limited effectiveness in removing bacteria.
