1. Put an independent appliance thermometer inside the refrigerator and verify that it stays at or below 4°C (40°F). Check the freezer against -18°C (0°F). Periodically verify the interior temperature rather than assuming the control-panel number is exact.
2. Do not pack food tightly against every shelf and wall. Leave room for cold air to circulate and group frequently used items so you can find them without leaving the door open for long.
3. Keep raw meat, poultry and fish in leakproof containers or secure wrapping so their juices cannot drip onto other foods. A lower shelf is a practical location; keep them separated from foods that are ready to eat.
4. Refrigerate perishable food and leftovers within two hours of being left at room temperature, or within one hour if the ambient temperature exceeds 32°C (90°F). Divide large portions among shallow containers for quicker cooling.
5. Date containers when you refrigerate them. As general US food-safety reference periods, raw poultry and ground meat are kept one to two days, while cooked meat and similar leftovers are usually kept three to four days. Follow shorter package instructions and discard food if safe temperature control is uncertain.
6. If raw juices spill, isolate affected food and promptly clean the contacted surfaces. Harmful bacteria can be present without an obvious bad smell or taste, so never rely on smelling or tasting food to judge safety after a major temperature failure.

Lower shelf is practical placement, not a mandatory USDA zone.USDA FSISHow long can I keep meat in the refrigerator? ↗USDA reference storage intervals: ground meat and raw poultry 1-2 days, beef/lamb/pork steaks and roasts 3-5 days, cooked meats and seafood 3-4 days.FoodSafety.govCold Food Storage Chart ↗US government food storage chart for 40°F/4°C refrigeration and 0°F/-18°C freezing; general references do not override shorter package dates.Wikimedia CommonsFile:Open refrigerator with food at night.jpg ↗Actual original W.carter 2016 photo, CC BY-SA 4.0, author credit and license linked.
