Boiled water. Can you really sterilize?

Answer:

Can kill most, but some pathogens can not be killed by boiling water
Can kill part of it. Baby bottles don't need to boil for a few minutes to sterilize. However, some of the virus is not killed, like hepatitis B virus, what is the immortality of boiling water.
For tableware, high temperature boiling is indeed the most common way of disinfection, many bacteria can be sterilized by high temperature sterilization. Beijing city health supervision Li Dong told the "life times" reporter, however, hot water scalding hot bowl, but failed to achieve such an effect, can only remove the dust on the tableware.Reminder:To achieve the effect of high temperature sterilization must have two conditions, one is the role of temperature, and the other is the role of time.In general, pathogenic Escherichia coli, Salmonella, Vibrio cholerae, the majority of 10 to 100 degrees Celsius by high temperature for 1 - 3 minutes or 80 minutes heating to death. Therefore, before eating a bowl of hot water with boiling water, can only kill a very small number of micro-organisms, boiling, circulating steam or the use of infra-red disinfection cupboard is an effective way. "Of course, scalded with boiling water in a bowl at least can wash away the dust or oil, this is not a bad idea."
Although you can not kill all the bacteria, but also can reduce a lot ah, reduce the risk of diarrhea and so on. There you have finished cooking utensils, pouring water can take away a lot of bacteria, dust, residual detergent, etc.. Of benefit. Also, do not want to belong to the hepatitis B virus, is a virus, usually cook half an hour on it.Hepatitis B virus (HBv) has a strong resistance: it is hot, low temperature, dry, UV, the general concentration of chemical disinfectants can be tolerated; in 20 degrees below freezing also can not live it, can live for 20 years! In 30 - 37 degrees can survive for up to 6 months, at more than 37 degrees can live for 7 days, at the time of 55 degrees can live for up to 6 hours. The commonly used disinfectants on weekdays, such as alcohol, Lysol, iodine and so it doesn't work at all, not to kill them, so the family had hepatitis B patients do not use these disinfectant to disinfect, but HBv is afraid of heat, such as heating to 100 degrees, 10 minutes to lose infectivity. HBv is very sensitive to 0.5% peracetic acid, a strong oxidizing agent that kills them. 3% bleaching powder, 0.2% new clean out can also be used to kill HBV.
