a.When they tear, become soiled, after a task, or after four hours of continuous use with the same food
b.Only at the end of the shift, when the pair is discarded along with the soiled apron
c.When the person in charge inspects the line and tells the cook to swap to a fresh pair
d.Once per four hours of continuous use, regardless of tears, soil, or a change of task

解析

Gloves must be changed when they are torn or soiled, when switching tasks or foods, after handling raw meat before touching ready-to-eat food, and at least every four hours of continuous use. Waiting until the end of the shift lets contamination build up for hours, and a glove change should never wait on a manager noticing it. The four-hour interval is a ceiling, not the whole rule: applied alone it ignores tears, soil, and task changes, which is why it is not the best answer.

法律依据: FDA Food Code §3-304.15
