Does the cold kill bacteria? Cold Temperatures and Bacteria
While cold temperatures don’t necessarily kill bacteria, they can slow or stop the growth of bacteria. This means the bacteria won’t reproduce quickly, but it also won’t be completely destroyed. For example, Listeria will stop growing completely in the refrigerator, but it doesn’t die.
Does keeping it cold kill germs? Hot temperatures can kill most germs — usually at least 140 degrees Fahrenheit. Most bacteria thrive at 40 to 140 degrees Fahrenheit, which is why it’s important to keep food refrigerated or cook it at high temperatures. Freezing temperatures don’t kill germs, but it makes them dormant until they are thawed.
What temperature will kill bacteria? Bacteria multiply rapidly between 40 and 140 degrees. Bacteria will not multiply but may start to die between 140 and 165 degrees. Bacteria will die at temperatures above 212 degrees.
Do germs thrive in heat or cold? Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic. There are exceptions, however. Some bacteria thrive in extreme heat or cold, while others can survive under highly acidic or extremely salty conditions.
