Boiling water kills or inactivates viruses, bacteria, protozoa, and other pathogens by using heat to damage structural components and disrupt essential life processes (such as protein denaturation). Boiling is not sterilization, but is more accurately characterized as pasteurization.

Can salmonella be killed in microwave?

Microwaves do not kill bacteria, but heat does. The higher the temperature, the faster those bacteria die. The “instant kill” for most bacteria (including Salmonella) is about 160° F (71° C). They need only a few seconds at this temperature.
