This list is from statistics published by the Center for Disease Control. In order to compile the list, researchers visited 35 U.S. homes, swabbing for bacteria in 32 locations in each home. Once you have read this list – if you feel the urge to clean, the FDA recommends 1 teaspoon of chlorine bleach to 1 quart of water for home disinfecting. Get scrubbing!

It would really help if someone could calculate the way this information affects the 10 second rule, please.
Not that it matters. I like bacteria. Makes my pork extra spicy.
Kwame: I prefer not to use the 10 second rule – I have my own: If no one saw it – it didn’t fall!
The five-second rule was also featured in an episode of the Discovery Channel series MythBusters. The results they got showed time was not a factor when food is exposed to bacteria; even two seconds’ exposure is more than enough time to contaminate it.
Wikipedia: 5 Second Rule
5 or 10 second rule ‘myth’ dispelled!
i love Wikipedia and Mythbusters!
Better than the timing rule is the “If you touch the handles on doors in public buildings, food off the floor is the least of your concerns” rule.
Kwame: that is so true you know – since I started washing my hands whenever I come home from being out, I have had far fewer colds.
That’s a good rule jfrater, but the scary thing is, you know they use YOUR rule in fast food places. I know… I used to work in one *dun dun dun*
My Mom is a germaphobe and is constantly using that disinfecting hand rub. I have tried to explain to her that exposure to germs is actually a good thing, in that it helps the immune system build immunities to the most common germs.
Vanna: haha – do you mind telling me which one? (I will avoid henceforth!)
soonerproud: I agree with you – and I have a friend in the very same boat as your mother – it can be quite annoying, but you have to be patient because it is not the fault of the person – it is a type of disorder – though luckily not one that is debilitating in most cases.
Another place to pick up uber amounts of bacteria is the handle on your local grocery store shopping carts, and if you have seen the kinds of individuals that come and go from Walmart…….”shiver”
Joe: And just to think about all the mothers that allow their babys to put their mouths on the shopping cart handle. ewwww
Joe Rosson: Ok – I buy all my groceries at the farmer’s market – and the extra bits I need I get online – but if I have to go to a grocery shop – I wlll definitely wear gloves from now on!
Farmers market? I take it you are single. I have two teenage eating machines at home so I must go with bulk, I hit Sams club often. Farmers markets are nice but they don’t have much of a selection when it comes to family shopping.
JOE ROSSON:
The grocery store I shop at (Crest in Edmond OK) supplies disinfecting wipes for people to wipe down the handles of the carts with.
jfrater: I would shop at the farmers market too except it is only open for half days on Saturdays in the town I live in. The next closest one is about 20 miles away and is too far to drive for normal shopping.
if i’m not mistaken Jaime is ‘across the pond’. well to me. i’m in Texas and i think he’s in England? i know from friends there outside ‘the big cities’ there are still areas that have local ‘farmer’s markets’ …usually daily. unlike here where its seasonal and on Saturday, early mornings.
i think people here tend to forget how rural huge chunks of ‘over there’ are..or near rural. course here even in the country you can find a grocery store. especially in Texas. one on damn near any corner. and too, there are lotsa places ‘over there’ that people still shop daily for the evening meal. unlike our buy in bulk and freeze and zap in the microwave mentality. they actually prepare entire meals FRESH…LOL. and really who’s to say which is better or worse. some things are more dictated by time and money than anything else.
apparently you haven’t seen my keyboard and mouse.
I am in England – London in fact (though I am not English!). The market I am referring to is Borough Market – it is a huge market held 3 days a week where all the finest food comes together in London for the restaurants. You can get rare pig breed meat, freshly killed rabbits and game, and virtually all of the finest foods imaginable (which is quite a treat for England, the home of bad food – in my experience so far. The meat is aged as it should be (a month or more), the cheeses are made by hand and matured, the vegetables are picked that day, and the coffee is the only decent coffee in England. It takes me 30 minutes by car to cross the city to the market but there is plenty of parking and I miss good food so much that I am willing to make the trip.
Tomorrow I am going to get a good Bresse chicken for chicken and leek pie, and a freshly killed rabbit for a nice French dish I have discovered. It will be my first time skinning and gutting a rabbit so hopefully it all goes well – but I may only be posting sporadically as I will be chained to the stove, so to speak
what i grew up w/ here in Texas was the weekly ‘farmer’s market’ that was exclusively produce and home made items like jams and sauces. its not til you get to some larger cities here and certainly ‘over there’ that you see more variety like w/ game and fish. the local farmer is essentially gone here replaced by the huge corporate farms. and the mega grocery stores have taken over..HEB a regional chain has gone ‘Walmart’ w/ more than groceries in a new mega-store format. all this in just a few generations too.
yea cyns case goes for iowa too. I even live in a relatively rural area and, though we have farmers markets once in a great while, everything we buy is packaged (well..my family does grow a few things themselves, and we get fresh hunted game). I’m kinda envious of jamie for having such a luxury available even if thrity minutes away
wow..Ben..would’ve thought Iowa had more family farms still..that’s sad. so its like all mega farms now, eh? during the various hunting seasons the little Mom and Pop stores or butcher shops in smaller towns will offer deer sausage or dove or whatnot..you won’t see game in grocery store chains…lol.
well we still have plenty of farms yes and theyre not big commercial ones, but not alot of farms with livestock, mostly just corn and beans. what is livestock just goes to a packaging plant and comes out at the supermarket like any other meat in the first place. Unfortunately theres no doves for us here, its illegal in our state (not sure why, theres plenty)
The problems you are both experiencing there are happening here as well – most people are so used to supermarket meat that they would think a dark-red/brown (uncooked) steak was inedible when, in fact, it is the way it SHOULD be eaten. To make matters worse, people like Jamie Oliver advertise for the huge market chains on one hand and say you must have only the best ingredients on the other – making people think that that is what they are getting at the supermarket.
Let’s not go crazy with cleaning those though. Supergerms will be worse than a little winter cold.
Fascinating list! I think I’m going to go out and buy a thing of Purell. Haha! I wonder how they figure this stuff out. I’d hate to be the person who has to count all the bacteria for a living.
I don’t use Purell and the like because it is good to be exposed to common bacteria. Not being exposed can lead to a lot of problems. You need them to boost your immunity. That being said, I disinfect my kitchen every night. Table, counters, sink, fixtures, drain. It only takes a few minutes, and SO worth it. I love having a clean kitchen. Love to cook.
yo now we have to watch what we touch that crazy
We’re all gonna die from superbug diseases with everyone using all this antibacterial stuff. Don’t people realize that there’s a reason the products say they kill 99.9% of bacteria? That .1% is resistant and then guess what, that resistant bacteria replicates.
B_Rad- yup-yup!
This was cool when I found this because I am doing a science fair project on this
I heard one of the worst places for bacteria (not in the home but close enough) is the driver’s steering wheel. If that’s true then the outside front door handle should be just as bad if not worse…especially if you have a screen that blocks the UVB from santizing it.
Anyone ever think of pillows? Sure the cases are changed but the pillows themselves aren’t very often.
And the air ducts! In high school I had a friend whose senior research project involved going to the schools in our county as well as some family homes to take samples near air ducts. There are some disgusting things to breath in at a school but surprisingly, there isn’t a great difference between schools and homes. There were one or two molds or bacteria that were more aggressive in the schools but overall she found similar growths in all her cultures.
“I guess I will start eating dinner on the computer mouse instead of the tabletop from now on!”
Ewww. You eat food on a tabletop?? Where’s your plate???
There are more bacterial cells in the human body than there are human cells. So really, people, settle down and embrace your prokaryotic side.
You know Purell and any ype of hand sanitizers kill 99.9% of bacteria. But it also kills the good bacteria that fights off diseases. Using hand sanitizer is a bad idea.
I use the 1 millisecond rule.
#30.. Think again. For computer addicts, that might be VERY untrue. /:
uhh. I think this list is wrong. The toilet bowl should have the least amount of germs while the mouse should have the biggest amount of germs.
What happens if i use the loo, dont wash my hands and head straight to my PC to finish reading up this list on listverse?
@jfrater
lol I go by the same rule!
if no one saw me drop it,it didn’t happen!
The toilet’s flush handle has that very little germs?! I find that hard to swallow (not like I want to!). Lol!
This is quite a shocking list! I won't show this to my mom (a.k.a. Ms. Germophobe!)
More bacteria on a toy than a toilet seat? Really? Should I tell that to a child who hugs their favourite teddy bear then?
Right now I am touching 750 bacterias and typing on about 42 000 bacterias.. whew
