How Can Handwashing Dishes Increase Your Chances of Getting Sick?

Quoted article:

By Tyler Wells Lynch

Interviewed in the Richard Linklater film Waking Life, late American philosopher Louis H. Mackey posited that the most universal human characteristic is either fear or laziness. Whether or not this is true is subject to long, inflammatory debate—not a matter for an appliance forum—but one thing is clear: These two traits are what sell dishwashers, and as long as you’re human, you should have one.
Fear

If you clean plates by hand, you should be afraid. Very afraid. Deep within the microscopic chasms of your filthy, grime-infested kitchen sink are tiny little monsters with ghastly superpowers. They are legion, and there’s little you can do to stop them (cue the Super Friends theme).

One of these creatures is called Escherichia coli (you may know it better as E. coli ) and it’s really good at finding its way from the end of the digestive process to the beginning, if you know what I mean. It also loves to bathe in your sink. In fact, according to a University of Arizona study, sinks often host larger cultures of E. coli and other fecal bacteria than toilet seats.

And then there’s Salmonella, good for an all-expenses paid seven-day, six-night trip straight to the bathroom. Public health bulletins have done a good job of warning us about this nasty little bugger, particularly its presence in raw chicken, eggs and tainted fruits and veggies. But you probably didn’t know that it can survive for weeks in a dry environment and even longer in water. If you’ve handled raw chicken or made an omelet lately, there’s a chance it’s still lurking, just waiting to give you days of gastrointestinal distress.

All fear-mongering aside, there are innumerable species of bacteria that are currently squatting in that Jenga pile of dishware in your kitchen sink. Most of them are harmless, but some of them aren’t—and if you aren’t using a dishwasher, you continue to feed all of them. Like Ambrosia bearing garlands of food-borne immortality to the Greeks, you satiate them with your reliance on archaic sanitation methods.

This is where dishwashers come into play—or more importantly, good dishwashers. Most consumers assume that dish-washing is merely about scrubbing dishes and removing food soils. Wrong! Water inside that dishwasher must reach and stay at 155 degrees before dishes, pots and pans are sanitized and all those pathogens get swept off to a watery grave.
Laziness

That’s the practical, hygienic reason why you need a dishwasher, but if Mackey’s theory is to be believed, there’s also a more ignoble reason: laziness. Let’s face it, washing dishes by hand sucks. It wastes hours that you could spend doing other things like working, cooking, or going to the store and buying a dishwasher. If you’ve got plenty of time on your dishpan hands, perhaps you’ll be swayed by a recent study from the University of Bonn in Germany that shows that automatic dishwashers use less water and energy than handwashing.
Dishwashing

So what are you waiting for? If you’ve got space for a built-in dishwasher, your options are numerous. Just look for a machine that promises water temperatures over 155 degrees. It’ll usually advertise a “sanitize” feature, which super-heats water to kill bacteria. It doesn’t matter if the sanitize feature is a standalone cycle, as on the relatively inexpensive GE GLDT696TSS, or a simple add-on, like in the higher-end Electrolux EIDW5905JS.. The Fagor LFA-65 IT X even lists on its control panel the precise temperatures reached by each of its respective wash cycles.

If you’re an apartment dweller, even cheap, portable, counter-top machines are capable of heating water to levels that kill most bacteria. So if your landlord won’t install a built-in, these compact machines work with just a sink and an electrical outlet.

We all know dishwashers are expensive. I cleaned a lot of plates in Memphis myself. But I’ve also had strep throat nine times, which is caused by Streptococcus pyogenes—a species of bacteria that can thrive in (surprise surprise!) moist environments. Of course, I can’t prove I caught strep so many times simply because I opted to wash my dishes by hand. But the fact remains: Manual dish-washing is extremely unsanitary. Not only does it increase your own chances of transmission, but anyone who eats off your squalid dinnerware is also more likely to catch a nasty bug or two, which probably explains why I had so few second dates.

If a legitimate fear of contaminated dishware doesn’t motivate you to get a dishwasher, just let laziness take over. It may confirm Mackey’s worst nightmares about humanity, but at least it might keep you, your friends and family from getting food poisoning.

This Edgestar counter-top dishwasher gets hot enough to kill bacteria on dirty dishes.

What is the most highly-sanitized place you can be? A hospital. Where do people acquire more diseases than they came in with, and often the worst possible ones like MRSA? A hospital.

Why is this? Microbes fight each other more effectively than chemicals and temperature can. Not possible to kill them ALL, leaving the most opportunistic behind unchallenged.

Yeah, sequester raw meat and poultry. But from the evidence above, it would appear that the strongest sanitation measures enable the worst problems. IOW, obsessing over sanitation may be worse for your health than just common sense. After all, how many people come down with MRSA in their homes?
 
I would imagine that the high alkalinity and in come cases the chlorine enables the work to be done at around 140F. As for the germ-harboring crevices in the sink, we always used a dishpan for washing dishes and we never rinsed in a sink full of water, but rather under the faucet and the water heater was kept at 160F. In spite of that, my parents did think that the transmission of colds declined after we got the DW, but we never had food poisoning type illnesses from hand washed dishes. Then colds went up when they got an electric toothbrush and the rest of the family's brushes were stored together and they all used the power handle thing. I brushed by hand and stayed well.

Having a dishwasher is much nicer than having to wash by hand any way you figure it. I was not too impressed by the reliability reports of the little countertop machines when I was looking for a DW for mom's retirement apt so we went with the KA top load portable.
 
Faster Yet

A lady at our church is lovable, funny and a bit more than messy. She said she can do her dishes in under 5 seconds with the flip of a switch. Light Switch
 
We didn't have a dishwasher between the years 1966-1974 when I was growing up. We washed dishes by hand and no one was any worse for it. We followed some sensible rules---no washing things that touched raw meat with other items---and never had a problem.

And now, a nightmare story: I have a friend whose Mom washes the kitchen floor, then dumps the water from the pail into the sink and washes the dishes with it. I kid you not. Don't eat there, EVER.

I never wash a dish by hand in my house. Everything goes in the dishwasher. I bought a bottle of dishwashing liquid when Smokey The Maytag was awaiting recall repairs four years ago and only recently threw the remainder out.
 
Another approach

Old joke, but one I like:

A guy has dinner with a friend. The dishes don't seem very clean. But the friend assures him that the dishes are "as clean as Soap and Water can get them!"

After dinner, the friend sets the dishes on the floor, and yells: "Here Soap! Here Water!"
 
" I bought a bottle of dishwashing liquid when Smokey The Maytag was awaiting recall repairs four years ago and only recently threw the remainder out."

We'll just hope there isn't some sort of Murphy's type law that says something like: toss your hand wash dish detergent out, and the dishwasher will soon break!
 
Eugene, maybe you should do a pagan style ceremony with a sacrifice of a box Cascade!

Seriously, though, I think in my dream kitchen I'd have at least two dish washers. (Although, at present, I'd be happy if I had one!) That way, there is a backup. And two dishwashers would be handy for huge cooking sprees.
 
I know that the hotter the water, the better dishes are cleaned. My mother would say you need to have have scaulding hot water at least to rinse them in and kill germs. I have a dishwasher and use it for my everyday Melmac and everything else,I hate hand washing. My oil hot water boiler is set at 150 and the dishes are cleaned just fine with the cheapest Walmart detergent. But dont try to use Melmac in the microwave. It gets very hot and the food is still cold!
 
I have to say when it comes to dishes and laundry

That my partner and I are HIV poz for many many many years 22 plus that. A lot of our longitude in life has been a great dishwasher and a washer that gets up to 205 degrees ... we have to be careful of where we eat since we can sense disturbances in our health balance. we do have very soiled Landry. We are the remnants of the time they threw darts at a wall to figure out what the hell would help us. Now with DNA Identification we are able to target the drugs better but damage we have done to our bodies will last the rest of our natural life
 
NSF Minimum Dishwashing Temp requirements.

For commercial Dishmachines are as follows.
Stationary rack machine (Door or hood type) wash-150F, final rinse-180F
Single tank rack conveyor machine: wash-160F, final rinse-180F.
Multiple tank rack conveyor or flight machines: prewash-120F, wash-150F, power rinse-170F, final rinse-180F.
This will heat the dishware up to a surface temp of 160F or hotter for a minimum of 10 seconds to achieve bacteria kill.

These temps are extremely critical and a kitchen will be shut down immediately if a health inspector finds a noncompliant dishwasher. The only exception to this rule is if the machine uses a chemical sanitizing agent the temps can be lowered. Manual warewashing in the 3 compartment sink is frowned upon even when a sanitizer is used in may healt jurisdictions as it is not generally as effective as a dishmachine.

All that being said there is overwhelming evidence in favor of using a dishwasher for sanitary reasons. This would apply to the home as well as commercial/institutional kitchens.

Not All Bad:

One of the problems with hand-washing dishes is that most people have no earthly idea how to do it. They commit four major sins:

- Not scraping or pre-rinsing dishes. Their dishwater ends up full of food particles, which are bacteria-laden, and can lodge in crevices.

- Not using hot enough water, claiming that their dainty hands can't handle it - and this plaint comes every bit as often from guys as it does women. Maybe oftener.

- Not using enough dishwashing liquid, and using a cheap brand. Good brands cut grease effectively, and grease is one of bacteria's best friends.

- Using dishwater too long. Oh, it starts out all hot 'n sudsy, but by the time Milady has drudged her way through eight place settings, the silver and some pots and pans, it's stone cold with a greasy scum on top.

No, no, NO.

SCRAPE the dishes with a rubber spatula. Use the HOTTEST water your hands can take. Use PLENTY of GOOD dishwashing liquid. And fa goodnitz sakes - CHANGE the water when it begins to cool off noticeably.

If someone in the house is sick, a little pre-soak in hot sudsy water to which you've added some liquid chlorine bleach is a great idea.

A dishwasher is a great thing to have, but you can have sanitary dishes without one.
 
watch me get bopped over the head for this...

I'm not disputing the fact that machine dishwashing does do a great job of killing germs, and bacteria. But I do think "How Using a Dishwasher Can Decrease Your Chances of Getting Sick" is a better title. I suppose if you piled dirty dishes directly in the sink you could end up with germ-laden plates that no amount of rinsing would take care of, especially with the drain right there. I live alone and although my kitchen originally had 2 built-in dishwashers, I find it easier and more practical to do dishes in a big dishpan with hot anti-bacterial soap. My normal daily load consists of a coffee cup, 2 parts of the coffee maker, a glass or two and a plate and a fork and knife. If I waited for a full load in the dishwasher it would take a week or more. Even with rinse & hold I'd probably have a mold forest by the time I pushed the wash button. I do have the dog's dishes but I'd never put them in the dishwasher...I like to keep people and dog stuff seperate.

My mom always had a dishpan full of hot soapy water whenever she cooked and I am the same way...the last of a dying breed. I like having my hands always clean when cooking, so in a way the dishpan keeps me from getting sick in a way the dishwasher can't.

One thing's certain, one of the main ways to prevent sickness is to wash, wash, wash your hands. My doctor says using hand sanitizers is good, and that you shouuld avoid touching your eyes, nose and mouth when you're out and about. He said using those grocery cart wipes is a good idea too. A few months ago I contracted conjunctivitis...a fancy name for "pink eye." I thought I was gonna die. The expensive medicine was worse than the infection itself, like pouring sand and gravel in your eyes (and yes, I'm a big baby.) The eye doctor said I probably contacted the conjunctivitis by putting my fingers in my eyes.

I still use my dishwasher when I have company. If you saw some of my dinner guests you'd understand why.
 
Handwashing, AND....

....Good sanitary measures for countertops, sink and towels.

Countertops need to be washed down with a cleaning agent (soap and water is fine), not just dry-wiped with paper towels.

ANYTHING that has been contacted by raw meat, fish, poultry or eggs needs to be sanitized.

Towels need to be used for only one meal's prep, then washed. They belong on a rack when they're not being used, and they should never be laid on the counter (also, not slung over your shoulder).

Sponges can be sanitized in the dishwasher or microwave.

And PLEASE wash your sink when you're done - I use a little dishwashing detergent and one of those blue Scotchbrite scrubbing sponges. Most people's sinks have a brown glaze of nasties that haven't been properly cleaned away since Gerald Ford was in the White House.
 
Even with rinse & hold I'd probably have a mold forest b

Not necessarily. A former roommate ran the dishwasher once a week, max before I moved in. Then, it was maybe 2-3 times a week. There never was a mold problem. But then, the rule was that to fight mold, the dishwasher door was always left slightly open. (Well, except when being washed--although leaving it open then, too, might help wash the kitchen! As we discovered the day the latch broke.)
 
"Sanitizing" the sponge

in the dishwasher can be problematic, particularly, if the heated dry feature is turned off, or does not exist, and the sponge remains wet and warm for several hours. The hard wares are fine, because they are hard, not porous, and dry relatively quickly, even if the element is off.

Cooks Illustrated says that the best way is to hold the sponge (with tongs!) in rapidly boiling water for a full minute.

If one really wants to sterilize the sponge in the microwave, the sponge needs to be thoroughly wet, or it may well catch fire.

I almost NEVER use a sponge in the kitchen any more. I use dish cloths and brushes on a regular basis. My dish brush gets a bath in either 91% rubbing alcohol, or chlorine bleach weekly.

I am germ wary, but not germophobic, unless I am cooking to serve other people.
