why can't germ killers kill 100% of germs instead of 99.8?

It is a pretty arbitrary, untestable number, as others said.  It is not clear if they claim it kills that % of actual organisms, or that % of types.\n\nAnyhow, some types are resistant to chemical disinfectants.  These include spores, which have a very resistant coating, able to keep the bug inside alive even in dry conditions etc.  Others are the "acid fast" bacteria, such as Mycobacterium tuberculosis, which causes ... you guesses it... TB!\n\nMicro-organisms compete with each other in various ways, including a type of "chemical warfare", so many are resistant to various chemicals.  A lot of types live in unhospitable and variable environments, eg soil and rocks, too.  They NEED to be tough!\n\nI am a microbiologist.

It just refers to a shorter pasteurization.  There's nothing about the process that should be harmful to infants.

First of all, i'm so glad i'm not the only "weirdo" who thinks that 63 degrees is perfectly comfortable!\n\nOther than that, one of the reasons may be that germs survive better in warmer temperatures. Also, temperature changes are really bad for the body, so if her family is sweating during the night and then runs out into 35 degree weather, that can cause the immune system to not work so well. I have the opposite of this-- i'm always sick in the summer when its really hot out and really cold in my house.

For every 10 degrees Celsius the reaction rate tends to double.  But when you raise or lower the temperature of the body so that the temperature is outside of a small range of temperatures, the enzymes and proteins do not work efficiently or at all.\n\nLower or Raise the temperature enough and you kill the organism unless it is a simple one cell thermophile bacteria.

Bacteria dies with anti-biotics

Not much, actually-You dont want something that kills the bacteria in the mouth, because they are the primary protection against even worse things.  People who have to take very high doses of antibiotics often loss the bacteria in the mouth, and then have things like thrush, yeast, even massive fungal infections-and these are extremely hard to treat.  Toothpaste just scrapes the bacteria off the tooth, so the acidic waste products of the bacteria dont eat away the enamel.

it's thought not to be. it's just a variation on the kind of bacteria all women have. 10-30% just have it instead of the kind that isn't as harmful to babies.

Tisa, please research olive leaf extract, grapefruit seed extract, and most especially colloidal silver. These are very potent natural anti-virals/bacterials and can be taken for long periods without problems. The silver especially can be used topically and orally and is proven to kill over 650 types of viruses,bacteria,yeasts, and fungi. I get my silver from herbalhealer.com at 500ppm concentration which is the best for killing germs. I wish you good luck!

there are actually several reasons\none so if you contract something they can say..hey we said 99..9 not 100 percent..so the can get out of it...\ntwo the governments are not telling the whole story about stuff out there...that's way..a lot more then they let us know about...and it can not kill them all...period...\nand my last one is..if it did kill 100 percent it would take the skin right off your bones....\nand I know I would not like that much..\n\ngood luck\nsmile

heated to a specific temperature to kill bacteria...as in the cas of MILK.

I have the EXACT same problem. Although i do not completely understand why, but if you use ANTI-BACTERIAL soap, and scrub really well it will work. It took me months of suffering... but I I'm better now. You must scrum HARD. Good luck listen and you will get results

It's highly unlikely, for the simple reason that it's not in the interests of a parasite to kill its host. It's far more beneficial to make the host sick instead, and even better if the host shows no outward signs of infection but continues cranking out parasites.\n\nThe most deadly virus of all time, the 1918 H1N1 flu, is in common circulation today -- in fact, you have probably been infected by it! However, its virulence and deadliness have dropped dramatically so it's no longer an exceptionally lethal virus. This is precisely what is expected.

Only engines/machinery can give more than 100%....just another annoying phrase from the good old USA.....i.e when someone says give 110% etc.

Tough call, even if the question was about all humans not just all living things.\nZen monks would place rings on their staffs in order than they could jangle and allow small lifeforms to get out of their way so as not to be stepped on.\nTheir are no rings small enough to warn microbes and I am not sure that we should avoid killing some bacteria what might spoil our food or make our children sick.  (Do you wash your hands?)\nAnd what about those things which are not exactly alive?  Like viruses?\nWe do not kill every bug which enters our homes.  Some people are fanatical about this and others live with spiders and ants crawling all over the place.  Most of us would kill lifeforms we believe to be a threat to us or our families.  Some might even capture and release some species (including mice and larger lifeforms).\nSome things to consider include:  Are you affected by commercials which try to make you believe that you need to give someone money to buy a product which will kill some lifeforms to make you healthier or happier?  What happens to the lifeforms that become resistant?  Do you really want polio and smallpox living among humans?  How about 'skeeter and the west Nile virus?  or Maleria?\nLife is not simple.  Not for bugs.  Not for humans.\nAt least humans can think about what they are doing before they make a choice.

i am not sure but every pools i've visited use chlorine and people say it kills bacteria

Nope, natural selection/evolution leads to bacterial resistance to antibiotics. No antibiotic is perfect. If we wipe some out, there would still be some left.

I have been using colloidal silver for years as a natural antibiotic/viral at 500ppm and I haven't turned blue like some idiots will tell you. It kills over 650 types of viruses, bacteria,yeasts,and fungi. I just used it on my nephew's pinkeye and it was gone in one day. You have to research it yourself and decide. Also look up olive leaf extract, grapefruit seed extract,and oreganocillin.
