食源性疾病第 27 / 320 题
A deli makes chicken salad on Monday and holds it cold at 41°F. Under the Food Code, ready-to-eat TCS food held cold must be date-marked and used within how many days, counting the day of preparation as day 1?
a.3 days
b.10 days
c.5 days total, discard on day 6 (day of prep is day 0)
d.7 days
解析
Ready-to-eat TCS food held at 41°F or below may be kept for a maximum of 7 days, with the day of preparation counted as day 1. After 7 days the food must be discarded because Listeria and other pathogens can slowly grow even under refrigeration. Shorter counts are not required by the Code, and the 5-day framing here misstates the counting rule.
