I’m Susie Craig from Washington State University Extension.
For years, warm or hot water was recommended for hand washing. Ongoing hand hygiene research shows cold water works just as effectively. Some studies found hot water more irritating for those washing repeatedly throughout the day. Cold water is also more energy efficient.
In many parts of the country after natural disasters, Boil Water Advisories are commonplace. So, is it safe to wash with contaminated water? While it’s always best to use clean water, the Centers for Disease Control and Prevention states it’s generally OK in most cases to use tap water with soap for hand washing during Boil Water Advisories. Situations vary, however. Listen to advice from your local health department. Use a hand
sanitizer (60% alcohol) if you cannot wash with water and soap.
This is Susie Craig from Food Safety in a Minute.
