Good to know: Scope: home storage of common leftovers and perishable foods (Thanksgiving turkey, stuffing, gravy, pies, soups, casseroles, pizza, ham, deli meat, raw meat, poultry, fish and eggs) in a home refrigerator at 40°F or below or a freezer at 0°F or below. Times come from the foodsafety.gov Cold Food Storage Chart and the USDA FSIS leftovers and turkey guides; the fridge limits are for safety, the freezer times are for best quality only, because food kept frozen at 0°F stays safe indefinitely. Food left out more than 2 hours (1 hour above 90°F) is shown as unsafe to keep. Not included: canned and shelf-stable foods, fruits and vegetables, milk and cheese, baby formula and breast milk, home-canned food, restaurant or store storage, and package use-by dates (if the package date is earlier, follow it). These are general USDA times; a food that smells or looks wrong should be thrown out. Independent ToolsKo planner. Sources reviewed November 12, 2026.

How to use it (step by step)

  1. 1Pick the food from the list and choose whether it is going in the fridge or the freezer.
  2. 2Pick the day you put it away (leave it empty for today) and type how many hours it sat out first. Choose “Yes” if the room or outdoors was above 90°F.
  3. 3Read the date to eat or freeze it by and today’s status. Reheat leftovers to 165°F with a food thermometer before eating.

Words to know

40°F or below
The safe fridge temperature. Above it, germs that cause food poisoning grow fast. A cheap fridge thermometer shows the real number.
Best quality
How long frozen food keeps its taste and texture. After that it is still safe if it stayed frozen, just drier or blander.
Shallow container
A low, wide food box. Hot food cools quickly in it, so it spends less time at unsafe temperatures.
Food thermometer
A probe you push into the middle of the food. Leftovers are hot enough when it reads 165°F.
