Freezing does not kill germs; it simply inactivates them. Many bacteria and viruses can survive freezing temperatures and can become active again once thawed. However, freezing can reduce the number of viable pathogens over time, making it a useful method for food preservation. It's important to note that while freezing slows down microbial growth, it does not eliminate all germs.

Does freezing water kill germs?

Freezing water does not effectively kill germs; instead, it merely puts them in a dormant state. Most bacteria and viruses can survive freezing temperatures, and when thawed, they can become active again. While freezing can reduce the number of viable pathogens, it is not a reliable method for sterilization. Proper cooking or disinfection methods are more effective for eliminating germs.

Will freezing temperatures kill germs on a toothbrush in a sealed zip locked bag?

"Heat will most definitely kill germs but freezing them won't do the trick- in the same way a frozen fish could spring back to life when put back into water. You could just be preserving them. Enzymes are at work in germs and these are denatured by extreme heat but cooling them might only be slowing them down. Freezing does prevent their multiplication if the temp is at 0°F or less. When thawed, the surviving organisms can multiply again."
