The leftover shelf life calculator uses FDA and USDA food safety guidelines to tell you exactly how long your cooked food is safe to eat. Select the food type and storage method, enter when it was cooked, and get the safe use-by date, danger signs to watch for, and the correct reheating temperature — so you never have to guess whether last night's leftovers are still good.

How to Use the Leftover Shelf Life Calculator
Food poisoning sends over 128,000 Americans to the hospital each year — and a large portion of cases come from improperly stored leftovers. Knowing exactly how long a cooked food is safe to eat, which danger signs to watch for, and what temperature to reheat it to can prevent illness for your whole household. This leftover shelf life tool applies FDA and USDA guidelines to give you a clear, specific answer.
Step 1: Select the Food Category
Use the dropdown to find your food. Categories cover cooked meats (chicken, beef, pork, fish, ham), soups and stews, cooked pasta and rice, eggs, deli meats, and prepared dishes like casseroles and pizza. If you have a dish that combines categories (like a pasta chicken bake), use the most perishable component — in this case, cooked chicken at 3–4 days.
Step 2: Choose Refrigerator or Freezer
Select where the food is stored. Refrigerated food at 40°F (4°C) or below stays safe for days. Frozen food at 0°F (-18°C) stays safe indefinitely — but best quality degrades over months. The tool shows both fridge and freezer times so you can plan whether to refrigerate for immediate use or freeze for later.
Step 3: Enter the Date Cooked
Enter the date the food was cooked or stored. The calculator determines how many days have passed and tells you whether the food is still safe, approaching the limit, or past the safe window. It also shows the exact use-by date so you can plan meals accordingly.
Key Food Safety Rules
Always reheat leftovers to an internal temperature of 165°F (74°C). Never leave cooked food at room temperature for more than 2 hours (1 hour above 90°F/32°C). Store food in shallow airtight containers so it cools quickly and evenly. Label containers with the date to avoid guessing later. When in doubt, throw it out — the cost of a food-borne illness is far greater than the cost of discarding leftovers.

How long are leftovers safe to eat in the fridge?
Most cooked leftovers (chicken, beef, pasta dishes, soups, stews, casseroles) are safe in the fridge for 3–4 days when stored at or below 40°F (4°C). Some items — like cooked whole ham or hot dogs — last up to 7 days. Always use the specific food's guideline rather than a blanket rule.
What temperature should I reheat leftovers to?
Reheat all leftovers to an internal temperature of 165°F (74°C) to kill any bacteria that may have grown during storage. Soups and gravies should be brought to a boil. Use a food thermometer — color and steam are not reliable indicators of temperature.
How do I know if leftover food has gone bad?
Discard any food that smells off, has changed color, shows mold growth, or has a slimy texture. However, many dangerous bacteria (like Listeria and Salmonella) are odorless and tasteless, which is why following time guidelines is critical — do not rely on smell alone.
Can I refreeze leftovers that were previously frozen?
You can refreeze leftovers that were thawed in the refrigerator (not at room temperature). Refreezing may reduce quality (texture and flavor) but is safe if the food was never left above 40°F for more than 2 hours total. Do not refreeze food thawed on the counter.
What is the 2-hour rule for cooked food?
The FDA/USDA 2-hour rule states that cooked food should not sit in the temperature danger zone (40°F–140°F / 4°C–60°C) for more than 2 hours total. On a hot day (above 90°F/32°C), the limit drops to 1 hour. Discard any cooked food that has been out of temperature control longer than these limits.
How long can cooked meat be frozen?
Most cooked meats maintain best quality in the freezer for 2–6 months, though they remain safe indefinitely at 0°F (-18°C). Cooked poultry lasts 4 months, cooked beef and pork dishes 2–3 months, and cooked fish 4–6 months. Beyond these times the texture and flavor degrade but the food is not harmful if properly frozen.
