Safe food storage comes down to temperature and time. Bacteria multiply fastest in the “danger zone” of 40–140°F, so the goal is to keep cold food cold and not leave perishables sitting out.
The key numbers
Keep your refrigerator at or below 40°F and the freezer at 0°F. Refrigerate perishables within 2 hours of cooking or buying (1 hour if it’s above 90°F out). Cool large batches quickly — shallow containers chill far faster than one deep pot.
Rough storage times
| Item | Fridge | Freezer |
|---|---|---|
| Cooked leftovers | 3–4 days | 2–6 months |
| Raw poultry | 1–2 days | up to ~9 months |
| Raw ground meat | 1–2 days | 3–4 months |
| Raw steaks/chops | 3–5 days | 4–12 months |
Practice FIFO — first in, first out — so older items get used first. Freezing keeps food safe indefinitely; the time limits above are about quality, not safety, so freeze at peak freshness.
Frequently asked questions
What temperature should my fridge be? At or below 40°F; freezer at 0°F.
What’s the danger zone? 40–140°F, where bacteria multiply fastest.
How long are leftovers good? 3–4 days refrigerated; longer frozen.
When in doubt, throw it out — you can’t always smell or see the bacteria that cause foodborne illness. Labeling leftovers with the date they went into the fridge takes seconds and removes the guesswork about whether something is still within its safe window.
