The temperature required to kill bacteria depends on the type of bacteria and the environment in which it is present. In general, hot temperatures are more effective in killing bacteria than cold temperatures. Here are some key points from the search results:

• Temperature range for bacterial growth: Bacteria grow best in moist environments where the temperature of food is between 40-140°F (4-60°C). This temperature range is called the “danger zone” because food in this zone can become unsafe to eat very quickly. At room temperature, bacteria growth can double every 20 minutes.

• Temperature to kill bacteria: The only way to kill bacteria by temperature is by cooking food at temperatures of 165 degrees Fahrenheit or more. Cooking foods at 165°F (74°C) or higher will kill most bacteria. Preparing food and washing clothes at 140 degrees Fahrenheit or above can also kill most germs. Hot water with a recommended temperature of 140-150°F can kill viruses.

• Cold temperatures: Cold temperatures cannot kill germs, but only slow down their growth. Therefore, bacteria in cold temperatures will not be able to function, but if they are brought back to room temperature, they will start to grow again.

It is important to note that some bacteria can survive at very high temperatures. These types of bacteria are called thermophiles, which means “heat loving.” Thermophiles are harmless to humans and grow best at high temperatures.
