Does freezing kill flu bacteria?
First of all, the flu is caused by a flu virus, NOT a strain of bacteria and viruses - it's basically a bag of proteins that encapsulate DNA or RNA that can infect cells to hijack the host cell mechanism and initiate host cell immune responses to cause disease. Viruses are generally much more resistant than bacteria, and some of them can withstand temperatures from -20 degrees Celsius to 80 degrees Celsius, so eventually freezing won't work if your goal is to kill the virus. It depends on the conditions. Temperatures above 75 degrees Celsius will completely kill the virus, so this is your best choice.
Bacteria also tolerate cold and drought quite well, through the formation of spores.
@morphism No, this is a common property of bacteria to form spores, at least in the genus Eubacteria
