Germs on the Move: How Bacteria Spread From Surfaces to Food
In Germs on the Move: How Bacteria Spread From Surfaces to Food, host Harith Iskander explains why food dropped on the floor, no matter how quickly it's picked up, is covered in germs. Even if food is only on the floor for five seconds, bacteria and other harmful organisms can transfer to it. Learn how germs move from one surface to another, showing that our surroundings are always teeming with bacteria. This video is excerpted from BBC’s Got Science?, a science magazine series that explores and explains science in everyday life.
