Food in a kitchen spends a lot of its life waiting: in the steam table, the walk-in, a prep container. The Food Code sets rules for each kind of waiting.
Key idea
Hot holding: 135°F or above. Cold holding: 41°F or below. Reheating for hot holding: food cooked and cooled in the kitchen is reheated so all parts reach 165°F for 15 seconds, within 2 hours. Date marking: ready-to-eat TCS food kept more than 24 hours is labeled and used or thrown away within 7 days at 41°F, counting the day it was made as day 1. FIFO: first in, first out.
- Label every container: what it is, the date made, and the use-by date (and your initials, in many kitchens).
- Put new deliveries behind or under older stock, so the older is used first.
- Check hot and cold holding temperatures on a schedule, and write them down.
- Steam tables and hot-holding cabinets are made to keep hot food hot, not to heat cold food; reheat on the range, in an oven or a microwave first.
Why it works
Seven days is a limit for slow-growing germs such as Listeria, which can grow even in the cold. It is a safety limit, not a quality promise: many foods taste stale long before day 7.
Worked example: Use-by date
Chicken salad is made on Monday, March 3. What is the last day to use it under the 7-day rule (made day counts as day 1)?
- Day 1 is March 3. Day 7 is March 9.
Answer: Sunday, March 9.
Worked example: Reheating
Leftover soup from yesterday goes into the steam table at lunch. What must happen first?
- Reheat so all of it reaches 165°F for 15 seconds, within 2 hours.
- Then hold at 135°F or above.
Answer: Reheat to 165°F, then hold at 135°F or above.
Common mistake
Putting cold food straight into the steam table to "warm up". It spends far too long in the danger zone.
Practice at home
- Label everything in your refrigerator with masking tape: what it is and the date. After a week, see what you threw away and why.
In Meal Prep
- How long it keeps: leftovers and storage times at home
- Dates on packages: what "use by" and "best if used by" mean
