The temperature at which bacteria die depends on the type of bacteria and the environment in which they are present. In general, hot temperatures are more suitable for killing germs, but that does not mean that we should disinfect all items with heat. Washing hands often is the best way to prevent the spread of germs. Here are some key points from the search results:

• Bacteria begin to die at 149°F (65°C), but boiling water for one minute is still a good precaution.
• The only way to kill bacteria by temperature is by cooking food at temperatures of 165 degrees or more.
• 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.
• Cooking foods at 165°F (74°C) or higher will quash any bacterial uprising and ensure your food is safe to eat. The longer food is heated above 165°F, the more bacteria you’ll kill.
• 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.
• Most germs will die from 165 degrees F to 250 degrees F (121°C) within a couple of minutes. Thats the recommended temperature to heat up meat, fish, and pork before serving and eating. Only some viruses can be killed at 140 degrees F temperatures in hot water.

In summary, the temperature at which bacteria die depends on the type of bacteria and the environment in which they are present. Cooking food at temperatures of 165 degrees or more is a good way to kill bacteria. Hot water can also kill germs, but it is important to note that washing hands often is the best way to prevent the spread of germs.
