The bacteria in frozen food die. This is because bacteria need food, water, and a warm temperature in order to survive.
Most food poisoning bacteria become dormant and stop multiplying when frozen. Freezing does not necessarily kill these bacteria, but it can slow their growth and reduce the risk of foodborne illness. However, once the food is thawed, these bacteria can become active again, so it's important to handle and cook frozen food properly.
frozen meat has more bacteria as it is in the freezer with lots of other food
Stomach acid also kills most bacteria that you might swallow with you food.
Frozen food should not be left out at room temperature for more than 2 hours to prevent the growth of harmful bacteria.
Food spoilage happens when bacteria in the food is allowed to grow. The food heats up to room temperature or hotter and the bacteria grow allowing it to spoil.
No it doesn't to kill bacteria in frozen yogurt you would somehow disintegrate the bacteria which is impossible at this moment.
It depends on how quickly the food goes from room temp to frozen. If freezing occurs slowly, like when you put something into a normal household freezer, ice crystals are able to form in the cells and many (most) bacteria die. Some however, survive and are basically dormant (in microbiology the definition of "death" is that all cells are killed and cannot grow back). Refrigeration and freezing therefor are considered bacteriostatic, not bacteriocidal. When you remove the food item from the freezer it is not sterile, since some cells survive. Of course, you know this intuitively, because if you leave it out, it will "go bad". That is the bacteria recolonizing the tissues. If you are able to rapidly freeze cells (as is done in biology labs, with a ethanol slurry), water crystals do not have time to form. This is how cells are prepared to be stored in deep freeze and can be kept this way for long periods of time.
Freezing doesn't necessarily kill bacteria. It stops them from multiplying, but they can revive when the food is thawed. And the toxins they produced before being frozen will still be there.
Yes, frozen food can go bad if stored for too long due to freezer burn, loss of flavor, and potential growth of harmful bacteria.
The approved method for thawing frozen food is to thaw it in the refrigerator, in cold water, or in the microwave using the defrost setting. It is important to never thaw food at room temperature to prevent the growth of harmful bacteria.

Bacteria in food reaching a temperature of no more than 63c is very dangerous. Bacteria thrive at this temperature. Food is in what can be referred to as a 'high risk or danger zones'. Food should not be consumed and should be destroyed.
