Bacteria can be killed by high temperatures. The temperature at which bacteria die depends on the type of bacteria. Here are some key points from the search results:

• Most bacteria are rapidly killed at temperatures above 149°F (65°C) .
• The only way to kill bacteria by temperature is by cooking food at temperatures of 165 degrees or more.
• Hot water can kill germs, even extremely hot water with a recommended temperature of 140°F - 150°F will be able to kill viruses. In addition, this temperature can also help keep the human body safe from the effects of bacteria and other protozoa. For boiling water, a temperature of ≥160 degrees F will kill bacteria in Legionella water.
• Norovirus will die when exposed to temperatures exceeding 145ºF. Clostridium botulinum (the bacteria that causes botulism) will die when exposed to temperatures exceeding 250ºF. Salmonella will die when exposed to temperatures exceeding 165ºF.
• Bacteria grows 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. In fact, at room temperature, bacteria growth can double every 20 minutes.

In summary, the temperature at which bacteria die depends on the type of bacteria. However, most bacteria are rapidly killed at temperatures above 149°F (65°C). To ensure that food is safe to eat, it is recommended to cook it at temperatures of 165 degrees or more. Hot water can also kill germs, and a temperature of ≥160 degrees F will kill bacteria in Legionella water.
