Contamination & Hygiene第 102 / 240 题
When should single-use gloves be changed?
a.Only when they look dirty
b.Once at the beginning of each shift
c.When torn, contaminated, after handling raw food, or after four hours of continuous use, whichever comes first
d.Never, if hands were washed first
解析
Gloves must be changed when they tear or become contaminated, when switching tasks such as raw to ready-to-eat, and at least every four hours during continuous use. Hands are washed before putting on a new pair. Gloves that only 'look' clean can still be torn or contaminated with pathogens.
