Food Storage Containers: Start With the Right Fit
Choose containers that are intended for food use, free from cracks, and easy to wash thoroughly. A secure lid helps prevent leaks and protects food from contact with other items. Select several sizes so a small portion does not sit in a large container with excess air and unused refrigerator space.
Use a container that matches the food and the next step in your routine. A leak-resistant container works well for soups and sauces, while a shallow container is practical for leftovers that need to cool and be refrigerated. Check the product instructions before using any container in a microwave, freezer, dishwasher, or oven.
- Keep a few small containers for single portions and small amounts of ingredients.
- Retire containers with deep scratches, cracks, warped lids, or seals that no longer close.
- Store lids together in a way that keeps them clean and easy to find.
Cool and Refrigerate Leftovers Promptly
Divide large amounts of cooked food into shallow containers before refrigerating. Smaller portions can cool more efficiently than one deep, tightly packed container. Do not leave perishable food at room temperature while you organize the rest of the kitchen.
FoodSafety.gov recommends keeping perishable food out of the temperature danger zone as much as possible and using refrigeration as part of the chill step. Keep the refrigerator at 40°F or below, and avoid packing it so tightly that cold air cannot circulate. When you are unsure about a food's safety, use official guidance rather than relying only on smell or appearance.
- Set a timer or make refrigeration part of the cleanup routine after a meal.
- Leave enough space around containers for cold air to move.
- Use a refrigerator thermometer to check the actual temperature.
Label Containers for Visibility and Rotation
Label each container with the food name and the date it was prepared or opened. Labels make leftovers easier to identify when several foods look similar and help the household use older items first. Use removable labels or tape that will not leave residue on food-contact surfaces.
Place newer containers behind older ones and keep ready-to-eat leftovers where they are easy to see. A short weekly review can identify food that should be used soon, frozen according to appropriate instructions, or discarded based on official safety guidance. Date labels support organization, but they do not replace temperature control or safe handling.
- Write the contents, date, and an optional planned meal on the label.
- Keep a small use-first area at the front of the refrigerator.
- Do not treat a label alone as proof that food is safe to eat.
Clean Containers and Prevent Cross-Contamination
Wash hands before handling food and use clean containers, lids, utensils, and work surfaces. FoodSafety.gov identifies cleaning and separating as core food safety steps. Keep ready-to-eat foods away from raw meat, poultry, seafood, and eggs during preparation and storage.
Wash containers according to their care instructions and clean lids, gaskets, and corners where residue can collect. Let pieces dry fully before storing them or closing them around food. If a container cannot be cleaned effectively or has a persistent odor from spoiled food, replace it.
- Use separate preparation tools for raw animal foods and ready-to-eat foods.
- Clean spills in the refrigerator promptly.
- Keep raw foods contained and positioned to prevent drips onto other foods.
Use Containers to Reduce Household Food Waste
A container system works best when it reflects how your household actually cooks and eats. Keep frequently used sizes together, reserve a visible area for food that needs attention, and portion leftovers in amounts likely to be eaten. Clear or well-labeled containers make forgotten food easier to spot before it is too late to use safely.
Plan one short refrigerator check each week and connect it to an upcoming meal. Use EPA's food waste guidance to look for practical ways to prevent food from being forgotten or discarded. Store only food that you can identify, date, and manage within appropriate safety guidance.
- Choose portion sizes based on the number of people who will eat the food.
- Use a first-in, first-out order for prepared foods and opened packages.
- Keep a small inventory of containers so storage does not become a reason to delay refrigeration.
Know When to Check Official Guidance
Container choice cannot make unsafe food safe. Temperature, time, handling, and the type of food all matter when deciding how to store leftovers and opened packages. Use USDA FSIS refrigeration guidance and FoodSafety.gov for specific storage and handling questions.
Follow package directions when they provide storage instructions for a commercial product. For unusual foods, power outages, recalled products, or uncertain handling history, consult the relevant official source before serving the food. When official guidance indicates that food should be discarded, do not taste it as a test.
- Check USDA guidance for refrigerated leftovers and foods requiring refrigeration.
- Check FoodSafety.gov for the four basic food safety steps.
- Use FDA food safety guidance for general household food handling information.

Questions that need a little more context
What should I look for in food storage containers?
Choose containers intended for food use that are clean, intact, easy to wash, and able to close securely. Pick sizes that fit the portions you normally prepare, and follow the manufacturer's instructions for refrigerator, freezer, microwave, dishwasher, or oven use.
Should leftovers go into shallow containers?
Shallow containers can help divide large amounts of cooked food into smaller portions for refrigeration. Use them as part of prompt refrigeration and safe handling; the container itself does not determine whether food is safe.
How should I label food storage containers?
Write the food name and the date it was prepared or opened. Keep older items in front and use labels to improve visibility and meal planning. Labels help with organization but do not replace temperature control or official storage guidance.
Can I rely on smell or appearance to decide whether leftovers are safe?
No. Food can be unsafe even when it looks or smells normal. Use time, temperature, handling history, package instructions, and official USDA or FoodSafety.gov guidance when making storage decisions.
How do containers help reduce food waste?
Right-sized, visible, labeled containers make leftovers easier to find, portion, and use in a planned meal. A weekly use-first check can reduce forgotten food while keeping storage decisions tied to official safety guidance.
