Quick Answer
Boiling water is an effective method for killing viruses, with a minimum temperature of 161°F (72°C) needed to inactivate viruses in 1-3 minutes.
Boiling Water Temperature
Boiling water to a temperature of 212°F (100°C) is a common practice, but it’s essential to note that this temperature is not necessary for killing viruses. In fact, boiling water at 212°F (100°C) for just 1 minute can kill viruses such as norovirus, rotavirus, and hepatitis A virus. However, boiling water for 3-5 minutes at 194°F (90°C) can also be effective against certain viruses, including poliovirus and coxsackievirus.
Holding and Cooling Water
When boiling water to kill viruses, it’s crucial to hold the water at the desired temperature for a sufficient amount of time to ensure all pathogens are inactivated. After boiling, the water should be cooled to a temperature that’s safe for storage or use. This can be done by transferring the water to a container and letting it cool to room temperature or by pouring it into a cooler filled with cold water to speed up the cooling process.
Safety Precautions
When boiling water to kill viruses, it’s essential to take safety precautions to avoid accidents. Always use a pot that’s large enough to hold the water, and make sure the pot is securely positioned on the stovetop or heat source. Additionally, use a thermometer to monitor the water temperature, and be aware of the risk of scalding or burns when handling hot water and equipment.
