The average human hand harbors 150 species of bacteria, some harmless and even beneficial, others capable of causing serious illness. Any number of those bacteria can be left behind every time you touch something – and considering that in the United States, Americans actually touch about 300 different surfaces every 30 minutes, there are a lot of germs being spread around.
In fact, regular contact with household items is thought to be the trigger for over 65 percent of colds, 50 percent of all cases of diarrhea and 50 percent to 80 percent of food-borne illnesses.
Among the worst offenders are those objects you touch often but rarely clean, such as your kitchen faucet, TV remote control, doorknobs, refrigerator door handles, computer keyboards, mice and trackballs, and light switches.
