According to the FDA Food Code, how long should the entire handwashing process take, from wetting hands to drying?

解析

The FDA Food Code sets a minimum of at least 20 seconds for the whole process — wet, soap, scrub vigorously for 10 to 15 seconds, rinse, and dry — so 20 seconds total is the rule. About 10 seconds in total, and 5 seconds of scrubbing, are both under those minimums. And the Code sets a floor rather than a fixed duration, so 'exactly 60 seconds' misstates the requirement even though washing that long would do no harm.
