The two rooms that I feel has the most bacteria is the kitchen and bathroom.
The kitchen is the catch all place in my home. We have an island that our cell phones, purses and keys are placed on it along with mail. If you think of everywhere our cell phones and my purse had been during that day those bacteria and nasty stuff is being place on that counter top. Then I prepare dinner on that same island after clearing it off. When most of the time I do not wipe it down but will now base on what I found out.
While researching the most bacteria found in your household is found that the floor in front of your kitchen sink has more bacteria (830 per square inch) than the trash can (411 per square inch). (franco, 2013) Also that wonderful sponge that we use to clean our dishes is possibly spreading bacteria such as E. coli, salmonella, or campylobacter. It not only collects the bacteria and viruses but gives them the ideal breeding ground to reproduce.(boyer, 2012)
Bringing in groceries and sitting them on the counter also spreads germs brought in from out of the home. Thinking about bacteria I would guess that the fridge handle has tons of bacteria and viruses living on it as my kids go straight for the fridge when they get home from school without washing their hands.
The kitchen is by far the most germ ridden in my house and now I think twice about how clean I really thought it was. That sponge is going in the microwave after each use to destroy 99.9% of all the bacteria.
The other place that one thinks is full of bacteria and viruses is the bathroom. This is one place in my home that lacks the daily cleaning, we clean the bathrooms once and week. Looking in the bathrooms you will see dirty clothes sitting on floor, toothpaste that was spit out of my kids mouth dried up in sink, towels that we dry of with and wipe our hands, sink handles that we turn on to
