How long should a food worker scrub their hands with soap during proper handwashing?

Hands must be scrubbed vigorously with soap for at least 20 seconds, covering the backs of hands, between fingers, and under the nails. The whole process — wet, soap, scrub 20 seconds, rinse, and dry with a single-use towel — should take about 40 seconds. Five seconds is far too short to remove pathogens.
