Washing hands in cold water 'as good as hot'

The small study of 20 people found using water at 15C (59F) left hands as clean as water heated to 38C (100F) .

The report, in the Journal of Food Protection, suggests this could help cut electricity bills in restaurants.

NHS advice recommends that people wash their hands in either cold or warm water.

In this study, scientists at Rutgers University-New Brunswick wanted to find out if popular assumptions about the benefits of warm or hot water and official guidance on hot water - given to the food industry in the US - held true.
