Freezing temperatures don’t kill germs, but it makes them dormant until they are thawed.

Does cooking meat kill all bacteria?

Cooking food to 160 degrees F will kill most bacteria. (Some meats need to be even hotter. … But if the food has been at room temperature for more than two hours, bacteria may have accumulated to dangerous levels and formed heat-resistant toxins that cannot be killed by cooking.
