What is the minimum temperature required to wash clothes / bed clothes, worn / comming into contact with an MRSA infected person to kill the MRSA bacteria ?

I have been told by a reliable source with in the health service,that they wash all their bedlinen at 60 degrees centigrade as a minimum for at least 30 mins.This they say is to eliminate all bacteria.You will find that most washing machines can wash at this temperature so it should not be a problem.Hope this is of some help.

I can't find the reference now.

but last year when I had MRSA, I read from the CDC (centre for disease and control, atlanta georgia) web-site that MRSA dies at 120 Celcius to maybe 150 degress celcius. thats hotter than boiling water. So how? wash your clothes on the hottest setting possible. then when drying, use a Gas dryer that goes up to 150 to 160 degrees celcius. The hottest setting possible. and then put the sheet out in the sunshine. surprisingly, MRSA dies in sunshine in 8 to 10 minutes, Sunlight contains UV light. MRSA dies under even very weak UV light exposure in 8 to 12 to 14 minutes. A doctor tried it, I read it in a book about sunlight.

basically the washing machine doesn't kill the MRSA. it just washes the MRSA away, the gas dryer on very hot setting, may kill some that are left, and the sunshine, will do the rest in. I think that's it, that's all you can do.

Alvin, I agree, sunshine can help enormously and it costs nothing - just a bit of extra care and time in the sunshine and fresh air can make all the difference. In large-scale hospital settings, the bedlinen could be treated with UV light as part of the laundering process. There are other simple, economical ways of preventing the spread of MRSA and these could be re-introduced into hospital routines or at home. Please refer to this article for some of my suggestions - 'MRSA: Healing Scents and Common Sense' at

I've read its 60 degrees + and that ironing is a good way to kill the bacteria. Sunshine does contain UV so common sense suggests that if you can dry laundy outdoors then this may help if UV kills MRSA.

I'm curious about all the UV sunshine talk... I received MRSA through salt water. That is very much exposed to sunlight and its UV rays. So how does it kill the bacteria? I also read something put out by the health department saying NOT to dry infected items outside but rather in a high temp dryer. Is the difference drying in a dryer, THEN letting sit out in the sun?

It is VERY unlikely that you got MRSA through salt water. Why do you think you did? It's MORE likely you got it when you dried off.

Does salt water kill MRSA? My son keeps getting it in the diaper area and he has another spot that looks suspicious. We are on vacation in flordia so we will be in the ocean alot.

If sunlight kills MRSA, why is this happening then?


AFP September 13, 2009, 12:39 pm

SAN FRANCISCO (AFP) - The so-called superbug MRSA, a multiresistant strain of staphylococcus usually found in hospitals, has been discovered for the first time on US beaches, a study said.

The antibiotic-resistant strain, which is increasingly found in prisons, gym locker rooms and homes, can cause skin conditions and organ ailments and serious and sometimes fatal cases of pneumonia.

"This is the first report of MRSA (Methicillin-resistant Staphylococcus aureus) from marine water and inertial beach sand," said Marilyn Roberts, a microbiologist at the University of Washington in Seattle and co-author of the study, during a press briefing Saturday.

The study was presented on the first day of the 49th annual Interscience Conference on Antimicrobial Agency and Chemotherapy (ICAAC), which is being held in San Francisco this weekend.

The study describes the discovery of the MRSA strain on five out of 10 public beaches along the coasts of Washington and California, where researchers collected sand and water samples between February and September 2008.

Ordinary staphylococcus was found on nine out of the ten beaches.

Sunshine does not kill MRSA. Uv light does and it takes a certain intensity of light to kill. Uv light is known muthagen of DNA and so is deadly pathogens. Sunshine can kill it, but not always. Depends on the day, the country ect.

Wouldn't it make sense for Hospitals to have UV lighting in their
lobbies and intake rooms...or are the extra days in isolation getting iv antibiotics more of a money maker where installing lighting is a cost?
Just a thought.

Lysol concentrate ( old fashioned kind in amber bottle) can be added to laundry to kill MRSA. Its hard to find in store. But if not availble locally can be found online at amazon. Sometimes Family Dollar and Walmart carry it. Another good disinfectant is the old fashioned (regular) Pine Sol. If I'm out of Lysol, I use this as well.

You can't just flood a room with UV light as it has rather unfortunate and detrimental effects on human DNA as well as microbes. UV light can badly damage your eyes and harm your DNA to cause skin cancer. An interesting proposal might be if hospitals installed UV lighting along with normal lighting and then, in addition to normal cleaning procedures, when a patient checks out of a room activate the UV lighting to flood the now unoccupied room with UV rays for about twenty minutes to help further reduce live bacteria levels before the next patient arrives.

1/4 cup hydrogen peroxide in rinse cycle. Or if front loader mix with cup of water
and add to detergent.

MRSA favors warmer tempertures, between the ranges of 59F up to 115F.
Temperatures radically outside these ranges will kill MRSA very effectively. Best success is at +or- 25 degrees either way, outside
this range for atleast 20 min exposure time. I have spent my life studying MRSA and have been infected with one of the worst strains
the CDC has ever seen for over 6 years. I am now weakened with multiple infections and close to death. If anyone has any new research or helpful information, Please email me anytime. I could use and appreciate any and all knowledge on MRSA. I am on a personal qwest to find a viable treatment for MRSA and give it away for free to the public because it is a killer.

Since this page comes up as a top Google result for "MRSA wash temperature" I want to point out that the old post above from Alvin Lim, who "couldn't find the reference", is completely mistaken. He has mixed up Celcius with Farenheit. 120-150 degrees Farenheit is about 50-60 degrees Celcius. When he says "basically the washing machine doesn't kill the MRSA", he's just plain wrong. A 60 degree Celcius wash cycle will kill MRSA. *However* many washing machines - especially newer ones - that say they're doing a 60-degree wash, actually don't get that hot, and/or only for a few minutes. Best to check your machine with a thermometer.
