How long should hands and arms be scrubbed during proper handwashing?

The recommended duration for scrubbing hands and arms during proper handwashing is 10 to 15 seconds. This duration is essential to effectively remove dirt, bacteria, and viruses, particularly when preparing or handling food. Scrubbing for this amount of time ensures that all areas of the hands, including under the nails and between the fingers, are thoroughly cleaned.

Research and guidelines from health authorities support this duration as effective in significantly reducing the presence of pathogens. While options suggesting shorter or longer times may not provide the level of cleanliness required, the key is that 10 to 15 seconds strikes an ideal balance between thoroughness and practicality for food handlers, promoting hygiene without leading to hand fatigue.
