Contamination & Hygiene第 90 / 240 题
How long should a food worker scrub their hands with soap during proper handwashing?
a.Just long enough to see suds
b.About 5 seconds
c.At least 20 seconds
d.At least 2 minutes
解析
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.
