Refrigerate now

Well within the 2-hour limit. Get them into the fridge right away, spread out in a shallow dish so they chill fast.

Chill it now

OK at ordinary room temperature. If it is hotter than 32°C (90°F), though, the limit shrinks to just 1 hour, so get them into the fridge at once.

Right at the limit

The USDA cut-off is two hours. If the room was warm, or you can't say for certain how long it has been, throw them out.

Throw it out

This is over the 2-hour limit, and bacteria could have grown, or made toxins that a round of reheating won't destroy.

Toss it

Baby food dinners left out overnight have sat for hours on end between 4°C and 60°C (40–140°F), the danger zone. Appearance is no guide here: it isn't safe to eat.

Anything warmer than 4°C (40°F) counts as room temperature. When it's hotter than 32°C (90°F), the limit drops to 1 hour.

Background

Getting to know baby food dinners

Baby food dinners sit in the baby food section of our food guide. The USDA FoodKeeper database files them under the name “Dinners”. Going by USDA FoodKeeper, they last 2 days in the fridge. As with any perishable food, they shouldn't spend more than 2 hours at room temperature. Best storage spot: cooked and ready-to-eat food sits on the upper shelves, higher than anything raw.

Breast milk, formula and baby foods come with stricter storage rules than most foods because babies are more susceptible to foodborne illness. Your pediatrician's advice and the product label always come first. Once a feeding starts, the baby's mouth introduces bacteria into the jar or bottle, which means leftovers shouldn't be kept for later.

Straight answers

Your baby food dinners storage questions

How long do baby food dinners last in the fridge?

2 days when held at 4°C (40°F) or below (opened). Start counting on the day it was bought, opened or cooked.

How long do baby food dinners last in the freezer?

Not listed. FoodKeeper does not list a freezer time for baby food dinners.

How long do baby food dinners last at room temperature?

2 hours at most, or 1 hour if the air is above 32°C (90°F). Throw out perishable food that has been out longer than that.

How long do baby food dinners last after opening?

2 days refrigerated after opening. As soon as the seal is broken, the date on the package no longer counts.

How long do unopened baby food dinners last?

Up to the package date, provided the seal is unbroken and it is stored the way the label directs.

How long is baby food dinners good after the expiration date?

Go by the date printed on the package. Labels such as "best-by" and "sell-by" are about peak quality and how stores rotate stock, not about safety — infant formula is the one product whose use-by date federal law requires.

How do you know if baby food dinners are bad?

Prepared formula or baby food that smells sour or off. Lumps, or separation that won't mix back in. Any shift away from its normal color.

How long can baby food dinners sit out?

At room temperature the limit is 2 hours, dropping to 1 hour when the temperature tops 32°C (90°F). A whole night out is never safe.

How to spot spoiled baby food dinners

Odor

Prepared formula or baby food that smells sour or off.

Texture

Lumps, or separation that won't mix back in.

Color

Any shift away from its normal color.

Seal

Damaged pouches, or jar lids that don't pop when you open them — throw them out.

Inspect your baby food dinners and tick each warning sign you see

No boxes ticked? That's encouraging. Even so, confirm how long it has been stored, because the germs behind food poisoning can't be seen with the naked eye.

Even one of these means it has spoiled. Toss it, and never taste it to find out.

What's happening

What makes baby food dinners spoil

Opened baby food and prepared formula are moist, rich in nutrients and low in acid, which makes them ideal for bacteria. Powdered formula isn't sterile and may contain Cronobacter. That explains both the short window for prepared formula and the importance of clean water and clean equipment.

Don't do this

Mistakes people make storing baby food dinners

  • Saving what's left in a bottle or jar to offer at the next feeding.
  • Feeding directly from the jar and then refrigerating what's left.
  • Heating bottles in the microwave, which can create hot spots.
  • Leaving prepared formula at room temperature longer than the label permits.
Freezer

Can you freeze baby food dinners?

No FoodKeeper timeFoodKeeper does not list a freezer time for baby food dinners.
  1. 1Step 1

    Freeze only what the guidance permits, in clean containers that seal.

  2. 2Step 2

    Write the date and the time on each one.

  3. 3Step 3

    Defrost it in the refrigerator or a bowl of warm water — never in the microwave — and never refreeze it.

Room temperature · 2-hour rule

Baby food dinners left out overnight

Baby food dinners kept out at room temperature beyond 2 hours (just 1 hour once the room tops 90°F / 32°C) should go in the trash. Bacteria grow fastest anywhere from 40°F to 140°F, and some of the toxins they leave behind survive reheating.

How to store it

Keeping baby food dinners in good shape

  • Should be discarded after use-by date.
  • Start with the label and your pediatrician's advice.
  • Put prepared or opened products in the fridge immediately.
  • Throw out any leftovers in a bottle or dish your baby has already fed from.
Package dates

What the dates on baby food dinners packaging mean

Before opening

Go by the date printed on the package. Labels such as "best-by" and "sell-by" are about peak quality and how stores rotate stock, not about safety — infant formula is the one product whose use-by date federal law requires.

After opening

The printed date stops counting the moment the seal is broken. Allow 2 days in the refrigerator, starting on the day you open it.

Shopping

Choosing good baby food dinners at the store

  • Confirm that baby-food jars are sealed and that the lid pops when you open it.
  • Never buy formula in cans that are damaged, bulging or leaking.
  • Look at the formula's use-by date: federal law requires it, and it is about safety.
Waste less

Baby food dinners: ways to finish them in time

  • Spoon a portion into a bowl rather than feeding from the jar.
  • Mix formula one feeding at a time.
  • Freeze homemade purees in ice-cube trays and thaw one portion at a time.

Test yourself

Baby food dinners myths: fact or fiction?

  1. 1.As long as they smell okay, baby food dinners are still safe after being refrigerated longer than 2 days.
    You got it!
    Not this time.

    False. Food-poisoning bacteria seldom alter how food smells. Keep to the 2 days window and discard anything older.

  2. 2.Putting baby food dinners in the freezer kills any bacteria on them.
    You got it!
    Not this time.

    False. The freezer puts bacteria on hold rather than killing them. They start up again as the food warms, so let it thaw in the fridge, then cook or reheat it all the way through.

  3. 3.Baby food dinners hold up well in the freezer.
    You got it!
    Not this time.

    Partly. FoodKeeper does not list a freezer time for baby food dinners.

  4. 4.Baby food dinners can be kept in the fridge door.
    You got it!
    Not this time.

    False. Each time the fridge is opened, the door heats up. Cooked and ready-to-eat food sits on the upper shelves, higher than anything raw.

  5. 5.Reheating baby food dinners thoroughly makes them safe after a night left out.
    You got it!
    Not this time.

    False. Certain bacteria produce toxins that heat cannot destroy. Reheating kills the bacteria themselves but leaves those toxins behind, so anything left out longer than 2 hours belongs in the trash.

Reader questions

Baby food dinners: frequently asked questions

How long do baby food dinners last in the fridge?
Baby food dinners last 2 days when refrigerated at 40°F (4°C) or colder (opened). That figure comes from USDA FoodKeeper.
Can you freeze baby food dinners?
FoodKeeper does not list a freezer time for baby food dinners.
How long can baby food dinners sit out?
The limit is 2 hours at room temperature, cut to 1 hour when it is hotter than 90°F (32°C). Past that point, throw them out.
How long do unopened baby food dinners last?
Go by the package date. Opened, the window shrinks to 2 days refrigerated.
How can you tell if baby food dinners have gone bad?
Odor: prepared formula or baby food that smells sour or off; Texture: lumps, or separation that won't mix back in; Color: any shift away from its normal color.
Do baby food dinners go bad after the printed date?
Go by the date printed on the package. Labels such as "best-by" and "sell-by" are about peak quality and how stores rotate stock, not about safety — infant formula is the one product whose use-by date federal law requires.
What temperature is best for storing baby food dinners?
Set the fridge to 4°C (40°F) or below and the freezer to -18°C (0°F). The dial on a lot of fridges is optimistic and the real temperature runs higher, so a cheap appliance thermometer is money well spent. A fridge running even a few degrees above 4°C will noticeably eat into the 2 days fridge window for baby food dinners.
What should I store baby food dinners in?
Use clean, sealed storage bottles or the original container, each labeled with the date and time. You want to block air and moisture, keep smells from traveling to other food, and be able to tell at a glance how old the food is. Jot the date on the lid or on a label so there is never any guesswork about its age.
Is the fridge door a good spot for baby food dinners?
Ideally, no. The door already runs warmer than the rest of the fridge, and it heats up further each time the fridge is opened. Cooked and ready-to-eat food sits on the upper shelves, higher than anything raw.
Can you refreeze baby food dinners?
Yes, but only when they defrosted in the refrigerator and have not sat out at room temperature. Anything defrosted in the microwave or a cold-water bath needs to be cooked before it goes back into the freezer. Quality drops a little with every freeze-and-thaw round, so freeze in portions you'll use in one go.
Does freezing kill bacteria in baby food dinners?
No. At -18°C (0°F), bacteria stop multiplying, but they aren't killed off. Once baby food dinners thaw, any bacteria that were there wake up again, so defrost in the fridge and, where relevant, bring it up to a safe temperature when you cook or reheat it.
If baby food dinners smell okay but are beyond the storage time, are they still safe?
Not necessarily. Food-poisoning bacteria usually leave the smell, appearance and taste of food unchanged. If baby food dinners have spent longer than 2 days in the fridge, discard them even if they seem perfectly normal.
