Some, but not all. Freezing may kill some of the present forms of bacteria. But for the most part, bacteria may simply freeze the growth state and then continue to grow once food has been thawed. A perfect and well known example of bacteria that cannot be killed through freezing is Salmonella.
To avoid getting sick, your best bet is to properly thaw and cook the meat before you eat it. Like any living population (ex. humans , ants , bees) a natural catastrophe produces a large number of deaths. But the effects are rarely "complete" , meaning that total annihilation is a bit of an impossibility.
The bacteria in your food belong to two criteria -
a) the "wanted" bacteria
b) the "unwanted" bacteria
However they both are bacteria - so the effect of the freezing will be proportionally same on both types. For the bacterial population (in your food) the freezing is a natural catastrophe ! A lot of them may get annihilated because of the severe shear pressures generated by water crystal formation.(Remember ice floats and therefore has more volume than water - for the same mass).
Some bacteria ( unwanted as well as wanted) will survive. That is because their "population" inside is quite huge to begin with. But they will find the going really tough - until the food is thawed ! But once thawed they will multiply quickly to recover populations. In fact this new generation ( according to Charles Darwin) will have more "freeze-hardy" bacteria among them !
Bacteria have been known to grow in extremely hostile conditions elsewhere on earth. Your frozen food hardly nears the "extreme" conditions they are known to survive in.

∙ 13y agoThe vast majority (if not all) of bacteria can survive being frozen, and simply remain stuck, but unharmed, in the food. This is why it is important to cook meat all the way through every time, as parasites and bacteria such as tapeworms and E. Coli can survive being frozen.
Scientists have found still live bacteria in the polar ice caps believed to have been there for thousands of years.

What organ kills bacteria?
The organ that kills bacteria is the stomach. The stomach produces acids that kill the bacteria as it digests food.
Does degreaser or disinfectant kill bacteria?
Disinfectant kills bacteria, degreaser is used to break grease and oils down.
What waves are used to kill harmful bacteria?
hi ***************** At least UVC, which is 100-280 nm in wavelength. http://en.wikipedia.org/wiki/Ultraviolet#Subtypes
What do you call a substance that destroys disease-causing bacteria?
if the bacteria is in the human body: antibiotics if the bacteria is on a surface: 70 % alcohol, UV light if the bacteria is in food or water: Heat, 100 degrees if possible, but remember that some bacteria produce alot of toxins if the are exposed to heat
Do methanol kill bacteria?
Yes, methanol does kill bacteria, especially if it is 70 percent or more, this allows penetration of the cell wall of the organism.
Will Refrigerating or freezing foods will kill any bacteria present in the food?
true
Are bacteria killed by freezing?
Yes, bacteria can survive freezing temperatures. Freezing isn't a sure-fire way to kill the bacterial population in the food. The only thing freezing will do is halt the multiplication of bacteria however thawing will resume the process.
If a food spoiled and then was placed in the freezer would it kill bacteria?
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.
Does uv rays affect food?
No. Uv (ultraviolet radiation) rays are used on food to kill unwanted bacteria withoud harmful chemicals.
Does freezing kill salmonella bacteria?
No, it doesn't kill much of the bacteria at all and the bacteria remaining will grow during defrosting.
Does freezing kill pneumonia bacteria?
Freezing does kill the bacteria because it freezes the cell movement. Bacteria has to maintain in movement to stay alive. Also when it freezes, it shatters easily. This kills the bacteria almost immediately.
What temperature does bacteria thrive in food tech?
Any temperature less than around 60 °C for most bacteria. However, there are bacteria in food that can survive past 100 °C. Freezing does not significantly kill bacteria, but puts it into a dormant stage, where they can no longer thrive and reproduce.
How does tinning food kill bacteria?
Food is cooked to kill bacteria as it is canned; the cans then keep out any new bacteria.
What are the method of preserving food?
Drying, Salting, Pickling, Fermenting, Smoking, Freezing, Cooling, Sugaring... Most methods involve taking water out of the food or inducing a concentration gradient to kill bacteria (by sucking water out of it). Others involve coating the food with some chemical that kills bacteria but is (relatively) safe for humans to consume.
How do you kill bacteria in food?
Boil it.
Is excrement safe to eat after freezing?
Freezing bacteria doesn't kill it. It 'slows' it down. When I mean 'slows' it down I mean that by it going to sleep or something. as soon as the bacteria defrosts, it comes back to life.
Does fruit essence kill bacteria?
Normally fruit essence is a food for bacteria. Acidic fruit, such as citrus, or vinegars, can kill some bacteria.
