D
hot water only rinse
30 second hand wash
Figure 8: Agar plates with bacteria A) before washing hands B) after rinsing hands in hot water C) After washing
hands with soap for 10 seconds and D) after washing hands for 30 seconds. Images show that the number of
bacteria on the plate are not greatly reduced after a hot water rinse or 10 second handwash but bacterial levels are
reduced after a proper hand wash for 30 seconds.
