Start with measured temperatures and storage history—not a sniff or taste test. Keep your refrigerator at or below 40°F (4°C) and your freezer at or below 0°F (-18°C), check how long perishables have been unrefrigerated, review food-specific storage times, inspect pantry conditions, and match products against current recall notices.
1. Measure refrigerator and freezer temperatures
Check the actual temperature inside each appliance with an appliance thermometer; a dial setting does not confirm the temperature of the food. FoodSafety.gov recommends a refrigerator at or below 40°F (4°C) and a freezer at or below 0°F (-18°C). See its food safety charts for temperature guidance.
Place a refrigerator thermometer where it can give a useful reading, and use a freezer thermometer for the freezer. If a reading is above the recommended limit, adjust the appliance and recheck it. The temperature reading is one part of the assessment: it does not by itself establish that food is safe if you do not know how long it was too warm or how it was handled.
2. Check how long perishables were unrefrigerated
FoodSafety.gov’s 4 Steps to Food Safety, reviewed September 18, 2023, says to refrigerate perishables within two hours, or within one hour when the surrounding temperature is above 90°F (32°C). The temperature range from 40°F to 140°F (4°C to 60°C) is where bacteria that cause food poisoning multiply most quickly.

Think through the food’s history: when it was prepared or removed from cold storage, how warm the room or outdoor setting was, and whether it went back into a properly cold refrigerator promptly. If you cannot establish that a perishable stayed within safe time and temperature limits, do not rely on appearance or smell to settle the question.
3. Use the right storage time for each food
Check the Cold Food Storage Chart rather than applying one rule to every leftover. For example, cooked meat or poultry leftovers keep three to four days in a refrigerator at 40°F (4°C) or below, according to the chart reviewed September 19, 2023.

It also features a 𝒎𝒂𝒙𝒊𝒎𝒖𝒎 𝒕𝒆𝒎𝒑𝒆𝒓𝒂𝒕𝒖𝒓𝒆 𝒅𝒊𝒔𝒑𝒍𝒂𝒚 for additional insights.
Write the preparation date on leftovers if it is easy to lose track, and use shallow containers when they help food cool and store promptly. The chart’s freezer time ranges are quality guidance for food continuously held at 0°F (-18°C) or below; they are not a universal refrigerator timeline. Pantry foods also vary, so do not infer an item’s shelf life from a general pantry temperature recommendation.
4. Inspect pantry conditions and packages
Look over dry goods, mixes, and canned foods for dates, damaged packaging, moisture, signs of pests, or exposure to heat. FoodSafety.gov’s Food Safety in a Disaster or Emergency guidance gives 40°F to 70°F (4°C to 21°C) as the best temperature range for shelf-stable foods and notes that heat accelerates spoilage.

The cited guidance gives general storage conditions, not a complete shelf-life schedule for every pantry item. For a particular food, consult applicable official food-specific guidance rather than guessing.
5. Match products against current recalls
Check current listings through FoodSafety.gov’s Recalls and Outbreaks, which surfaces federal recall information. Compare the notice with the product in your kitchen, including the brand, product name, dates such as use-by or freeze-by, and establishment number when listed. A recall applies to products that match its identifiers; a similar name alone is not enough to establish a match.

6. If a product matches a recall, do not taste it
Do not eat, open, or taste a recalled product to investigate it. Follow the specific notice’s return or disposal instructions. If the product was in your kitchen, clean affected surfaces and food-contact items as directed by the notice or official guidance. FoodSafety.gov explains what to do if you have a recalled product; illness-causing bacteria and viruses cannot necessarily be seen, smelled, or tasted.
How to prioritize what you find
Assess each item by its storage type and history instead of trying to rank all risks with one rule:

- Perishable or shelf-stable: perishable food depends on controlled time and temperature; pantry food depends on appropriate conditions and intact packaging.
- Temperature and time: consider measured appliance temperatures and how long food may have been outside safe cold storage.
- Food-specific storage interval: compare refrigerated foods with the appropriate official chart entry, not a rule for a different food.
- Package and pantry exposure: check for damage, moisture, heat, and pests.
- Recall identifiers: compare all relevant codes, dates, names, and brands in the notice.
Do not use sight, smell, or taste as a safety test. FoodSafety.gov cautions that illness-causing bacteria and viruses may not be detectable with the senses; decisions should follow storage history and official instructions.
