Actually, it doesn't. That's a myth left over from your grandparents who chose to hear what they wanted to hear instead of learning about Biology.
Freezing only slows the reproduction rate of bacteria down to a fraction of what it would normally be. That's why steak which would normally go bad in three weeks in your fridge will take two years to go bad in your freezer.
The reason for the reduction, in case you're curious, is that freezing causes the water molecules in the item to crystallize. This greatly restricts a microbe's ability to move around. In addition, most microbes also have water in them. This means that the microbes living on the skin and inside the outermost edges of the item will initially die off, reducing the overall population and slowing the spoilage.
Once the item in question is thawed, however, those microbes go right back to work. That's why, thawed meat wrapped in plastic will still spoil -- because the bacteria living inside it when it went into the freezer never left. They just took a nap.

Freezing food the action of bacteria?
Freezing food slows or stops the action of bacteria
Which o the following slow the growth of germs?
Keeping food refrigerated helps to slow down the growth of bacteria. Freezing food thoroughly is more certain to prevent bacteria from multiplying.
Do hot spices prevent the absorption of bacteria from food?
No, hot spices will not prevent absorption of bacteria from food, nor will it prevent bacteria from growing on the food.
What is the effect of freezing on bacteria?
Bacteria like Archaebacteria can survive in extreme temperatures but eubacteria cannot. Since Eubacteria die from the harsh temperature and Archaebacteria cannot reproduce your immune system kills all of the Archaebacteria. That is why freezing in a technical sense stops bacteria from reproducing.
What are the principles and methods of preserving fruits and vegetables?
The principles are to halt ripening, and prevent the growth of fungi and bacteria on the food. They are preserved by drying, canning, irradiating and freezing.
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.
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
Will Refrigerating or freezing foods will kill any bacteria present in the food?
true
What is the purpose of using refrigerators in Greenland by eskimos?
to prevent food from freezing.
How does pasteurization prevent food spoilage?
The main way that pasteurization methods prevent food spoilage is by removing the bacteria from the food. This is done by heating the food until it is hot enough to kill the bacteria and then holding it there long enough to make sure that all bacteria are killed.
How do you prevent most bacteria from surving?
keep the food hot
