What is the minimum temperature for washing hands?

The minimum temperature for washing hands is 100°F. This temperature is considered effective for effectively removing germs and contaminants from the skin. Washing hands with water that is too cold may not effectively remove grease and dirt, while water that is too hot can lead to skin irritation or burns.

Using water at 100°F strikes a balance; it is warm enough to encourage thorough handwashing without causing discomfort. Proper handwashing techniques emphasize the importance of using soap and scrubbing all areas of the hands for at least 20 seconds, and the right temperature helps facilitate a better lathering and cleaning action. This knowledge supports proper hygiene practices, ensuring food safety and minimizing the risk of foodborne illnesses.
