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.

JordanThe bacteria clogs up the insofagouse of the interpreted cell. The bacteria also spreads the most while freezing and the nucleus can not be preached without an in-viral detection (England treasures fact 1984). Therefore the microbe (bacteria) in freezing point spread and melt with the flange of the temperature.
I hope this helped :)

Peas can be canned or frozen Which of these will contain living bacteria?
Peas that have been canned will not contain living bacteria, as the canning process involves high heat that kills any bacteria present. On the other hand, peas that have been frozen may still contain some living bacteria, as freezing does not fully eliminate all bacteria.
Does all food contain bacteria?
No, not all food contains bacteria. While some foods naturally contain small amounts of bacteria, proper food storage and preparation can help minimize bacterial growth and prevent foodborne illness.
At what temperature will bacteria lay dormant on food in a freezer?
Food poisoning bacteria go dormant at and below freezing. All bacteria are dormant below -17ºC or 1.5ºF
Are all bacteria poisonous in food poisoning?
Not all bacteria are poisonous, but some pathogenic bacteria can produce toxins that cause food poisoning when ingested. These toxins can make people sick when they consume contaminated food. Proper food handling and cooking can help prevent food poisoning caused by bacterial contamination.
When food is put in the refrigerator all bacteria?
The growth of bacteria slows but does not stop. The food will still spoil but at a much slower rate.
