Refrigerate now

Well within the 2-hour limit. Get it into the fridge right away, spread out in a shallow dish so it chills 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 it 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 it 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

Milk left out overnight has 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.

Peak quality

Held at -18°C (0°F), milk is comfortably inside the 3 months quality window. Defrost in the fridge, then use it over the following day or two.

Peak quality

Held at -18°C (0°F), milk is comfortably inside the 3 months quality window. Defrost in the fridge, then use it over the following day or two.

Use it up soon

Safe, though it is reaching the end of peak quality. Plan to use it within a few weeks, since flavor and texture decline after 3 months.

Safe, but quality has slipped

Staying frozen solid keeps food safe with no time limit, but by 6 months you can expect flat flavor and some freezer burn. Use it in soups, sauces or baking, and cut away any dry gray patches.

Background

Getting to know milk

Milk sits in the dairy & eggs section of our food guide. The USDA FoodKeeper database files it under the name “Milk (plain or flavored)”. Going by USDA FoodKeeper and the FoodSafety.gov Cold Food Storage Chart, it lasts 1 week in the fridge and 3 months in the freezer. As with any perishable food, it shouldn't spend more than 2 hours at room temperature. Best storage spot: choose a middle shelf over the door, which warms up each time someone opens it.

Pasteurization kills harmful bacteria in fresh dairy foods like milk, cream and yogurt, yet they are still perishable once the seal is broken. Temperature makes a big difference to how long they hold up: a carton tucked toward the rear of a chilly shelf will keep noticeably longer than one riding in the door, which warms up every time someone opens the fridge.

Straight answers

Your milk storage questions

How long does milk last in the fridge?

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

How long does milk last in the freezer?

3 months at -18°C (0°F) for peak quality. It remains safe for as long as it stays frozen; past that point, flavor and texture slowly decline.

How long does milk 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 is milk good after the expiration date?

With perishable milk, time in storage counts for more than whatever the label says. Once it has spent longer than 1 week in the fridge, throw it out — even if the printed date hasn't arrived yet.

How do you know if milk is bad?

A sour or cheesy smell in place of a clean, mild one. Clumps, curdled bits or a body that has turned thick and slimy. A yellow cast, or a tint of pink, green or gray.

How long can milk 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.

Before you take a bite

How to spot spoiled milk

Odor

A sour or cheesy smell in place of a clean, mild one.

Texture

Clumps, curdled bits or a body that has turned thick and slimy.

Color

A yellow cast, or a tint of pink, green or gray.

Taste

If the first sip tastes bitter or sour, stop drinking and throw the rest out.

Inspect your milk 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 milk spoil

Some lactic-acid and cold-tolerant (psychrotrophic) bacteria either survive pasteurization or get in after opening. They ferment lactose, the natural sugar in milk, into acid, and that acid is what you notice as a sour smell, curdling or lumps. Mold can also form on top of sour cream, yogurt and products like them.

Don't do this

Mistakes people make storing milk

  • Keeping it in the door of the fridge, which is the warmest place.
  • Tipping leftover milk from a glass or pitcher back into the original carton.
  • Leaving it on the table for the length of a long meal.
  • Expecting thawed dairy to taste like fresh when you drink it; frozen dairy works best in cooking.
Freezer

Can you freeze milk?

Yes, in cooked dishes — 3 monthsHeld at 0°F / -18°C, it keeps its quality for roughly 3 months. Expect the texture to change, so plan to cook or bake with it.
  1. 1Step 1

    Pour out a small amount so the liquid has space to expand, then close it tightly.

  2. 2Step 2

    Freeze it standing up or lying flat, with the date written on it.

  3. 3Step 3

    Defrost it in the fridge, then shake or whisk it well; it works best in cooking and baking.

Defrosting

Safe ways to defrost milk

In the refrigerator

Move it from freezer to fridge the evening before you need it; this preserves the texture best.

On the counter

Suitable only for shelf-stable foods; perishables should never be thawed at room temperature.

Straight from frozen

Plenty of foods can go directly into the oven, a soup, a sauce or a smoothie.

Room temperature · 2-hour rule

Milk left out overnight

Milk 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 milk in good shape

  • Keep it at 40°F (4°C) or colder on an interior shelf rather than in the door.
  • Seal the container well, because dairy soaks up other smells in the fridge.
  • Pour out only what you need and put the rest straight back in the fridge.
Package dates

What the dates on milk packaging mean

Best-by vs. sell-by

Counting from the purchase date, FoodKeeper allows unopened milk 1 week in the refrigerator. 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.

Past the printed date

With perishable milk, time in storage counts for more than whatever the label says. Once it has spent longer than 1 week in the fridge, throw it out — even if the printed date hasn't arrived yet.

Shopping

Choosing good milk at the store

  • Grab dairy toward the end of your shopping trip and head straight home.
  • Reach to the back of the case for the coldest containers and the latest date.
  • Check that caps, foil and seals are unbroken.
Waste less

Milk: ways to finish it in time

  • Use it in baking: pancakes, muffins, biscuits and sauces all call for dairy.
  • Freeze small amounts, or fill ice-cube trays, to drop into cooking later.
  • Blend it into a smoothie before its window runs out.

Test yourself

Milk myths: fact or fiction?

  1. 1.As long as it smells okay, milk is still safe after being refrigerated longer than 1 week.
    You got it!
    Not this time.

    False. Food-poisoning bacteria seldom alter how food smells. Keep to the 1 week window and discard anything older.

  2. 2.Putting milk in the freezer kills any bacteria on it.
    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.Milk holds up well in the freezer.
    You got it!
    Not this time.

    Partly. Held at 0°F / -18°C, it keeps its quality for roughly 3 months. Expect the texture to change, so plan to cook or bake with it.

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

    False. Each time the fridge is opened, the door heats up. Choose a middle shelf over the door, which warms up each time someone opens it.

  5. 5.Reheating milk thoroughly makes it 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

Milk: frequently asked questions

How long does milk last in the fridge?
Milk lasts 1 week when refrigerated at 40°F (4°C) or colder. That figure comes from USDA FoodKeeper.
Can you freeze milk?
Held at 0°F / -18°C, it keeps its quality for roughly 3 months. Expect the texture to change, so plan to cook or bake with it.
How long can milk 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 it out.
How can you tell if milk has gone bad?
Odor: a sour or cheesy smell in place of a clean, mild one; Texture: clumps, curdled bits or a body that has turned thick and slimy; Color: a yellow cast, or a tint of pink, green or gray.
Does milk go bad after the printed date?
With perishable milk, time in storage counts for more than whatever the label says. Once it has spent longer than 1 week in the fridge, throw it out — even if the printed date hasn't arrived yet.
What is the source for these storage times?
They come from USDA FoodKeeper, the food storage database run by the USDA Food Safety and Inspection Service (FSIS). We last checked this page against the current FoodKeeper release.
What temperature is best for storing milk?
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 1 week fridge window for milk.
What should I store milk in?
Use its original container, lid on tight, on a middle shelf. 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 milk?
Ideally, no. The door already runs warmer than the rest of the fridge, and it heats up further each time the fridge is opened. Choose a middle shelf over the door, which warms up each time someone opens it.
Can you refreeze milk?
Yes, but only when it defrosted in the refrigerator and has 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 milk?
No. At -18°C (0°F), bacteria stop multiplying, but they aren't killed off. Once milk thaws, 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 milk smells okay but is beyond the storage time, is it still safe?
Not necessarily. Food-poisoning bacteria usually leave the smell, appearance and taste of food unchanged. If milk has spent longer than 1 week in the fridge, discard it even if it seems perfectly normal.
