The temperature required to kill germs depends on the type of germ and the environment in which it is present. Here are some key points from the search results:

• Most bacteria thrive at temperatures between 40°F to 140°F (4°C to 60°C), which is why its important to keep food refrigerated or cook it at high temperatures.
• Hot temperatures can kill most germs, usually at least 140°F (60°C) . However, some bacteria can survive at very high temperatures, and these types of bacteria are called thermophiles.
• Boiling water for one minute is a good precaution to kill bacteria, but the optimal temperature to kill bacteria is 149°F (65°C) .
• Freezing temperatures dont kill germs, but it makes them dormant until they are thawed.
• Some viruses can be killed at 140°F (60°C) temperatures in hot water.
• Cooking food at temperatures of 165°F (74°C) or more is the only way to kill bacteria by temperature.

Its important to note that while high temperatures can kill most germs, the most effective way to prevent the spread of germs is proper hand-washing. Other methods to prevent the spread of germs include disinfecting household surfaces, boiling water if necessary, and cooking foods to the proper temperature.
