USDA's FoodKeeper counts cream's fridge life from the day you buy it, not from the printed date: heavy cream 10 days, light cream 1 week, half-and-half 3–4 days. Ultra-pasteurized whipping cream keeps 1 month sealed, then 1 week once opened.
The printed date is the dairy's quality estimate, and FoodKeeper doesn't give a number of days past it. Cream kept at 40°F (4°C) or below may still be fine near its date. If it smells sour, has thickened or lumped, or you aren't sure, throw it out.

What the date on a cream carton means
No federal rule requires a date on cream. As FSIS has put it, except for infant formula, “product dating is not required by Federal regulation,” so the dairy chooses the date and the phrase. A sell-by date tells the store how long to display the carton, and USDA calls it “not a safety date.” A use-by or best-by date is the dairy's estimate of peak quality. See what “sell by” means and what “use by” means.
FoodKeeper's times work differently: they count from the day you bring the cream home. The two numbers won't always line up, and FoodKeeper doesn't say how they relate. When they disagree, the shorter one is the cautious plan. Sour cream is the exception: FoodKeeper gives it no days at all, just the package use-by date (see how long sour cream lasts).
Why ultra-pasteurized cream has a date weeks away
Federal rules set two heat treatments for cream. Regular pasteurization is milder: for cream, one of the allowed options is 166°F for 15 seconds (5°F hotter than for milk, because of the fat). Ultra-pasteurized cream is heated to at least 280°F (138°C) for at least 2 seconds, “so as to produce a product which has an extended shelf life under refrigerated conditions.” That is why a carton labeled ultra-pasteurized can carry a date weeks out while a pasteurized one is dated days out.
Two things don't change:
- It still needs the fridge. The regulation describes a longer life under refrigeration, not on the shelf.
- Opening resets the clock. FoodKeeper gives ultra-pasteurized whipping cream 1 month sealed but 1 week once opened. Write the opening day on the carton.
Milk follows the same pattern; see how long milk keeps for ultra-pasteurized and shelf-stable milk.
Heavy cream and whipping cream
By federal standard, heavy cream (which may also be labeled “heavy whipping cream”) has at least 36 percent milkfat, and light whipping cream (or just “whipping cream”) has 30 to less than 36 percent. Either can be pasteurized or ultra-pasteurized, and if it is ultra-pasteurized, the rules require that word on the main panel of the label, in letters at least half as tall as the product name. FoodKeeper lists them as two rows: heavy cream gets 10 days in the fridge from purchase, and ultra-pasteurized whipping cream gets 1 month unopened and 1 week after opening. FoodKeeper doesn't give a separate opened time for the heavy cream row.
Light cream
Light cream, which may also be labeled “coffee cream” or “table cream,” has 18 to less than 30 percent milkfat. FoodKeeper gives it 1 week in the fridge from purchase and 3–4 months in the freezer, with the freezer note “Use for cooking.”
Half-and-half
Half-and-half is a mix of milk and cream with 10.5 to less than 18 percent milkfat. FoodKeeper gives it 3–4 days in the refrigerator, counted from the day you buy it, and 4 months in the freezer. It has one row for half-and-half and doesn't separate pasteurized from ultra-pasteurized cartons.
If the date printed on your carton is further out than that, FoodKeeper doesn't explain the gap, and we haven't found a USDA source that does. The cautious plan is to finish half-and-half within FoodKeeper's window. Whatever either date says, throw it out if it smells sour or breaks into flecks in hot coffee.
Opened the carton for one recipe? The sealed-carton date says little about an open one. Scan the date when you buy it; when you open ultra-pasteurized cream, add it by hand with a date 1 week out. FreshScan reminds you at 9:00 AM two days before.
Buying cream for Thanksgiving
Thanksgiving 2026 is Thursday, November 26. Buy too early and pasteurized cream can run past FoodKeeper's window before the pies are made. Using the low end of each FoodKeeper range:
| Product | FoodKeeper, fridge from purchase | To still be inside it on Nov 26, buy on or after |
|---|---|---|
| Ultra-pasteurized whipping cream, sealed | 1 month | Monday, October 26 |
| Heavy cream | 10 days | Monday, November 16 |
| Light cream | 1 week | Thursday, November 19 |
| Half-and-half | 3–4 days | Monday, November 23 |
If you open ultra-pasteurized cream on Wednesday, November 25 to make pies, FoodKeeper's 1 week after opening runs to Wednesday, December 2. For the leftovers that follow the meal, see how long Thanksgiving leftovers last.
Can you freeze cream?
The sources don't fully agree, so here is what each one says:
- FoodKeeper gives heavy cream 3–4 months, light cream 3–4 months and half-and-half 4 months in the freezer, and lists ultra-pasteurized whipping cream as “not recommended” for freezing.
- NDSU Extension is stricter: it advises freezing only heavy cream with 40 percent or more butterfat, and says lighter cream and half-and-half “do not freeze well.” Heavy cream only has to reach 36 percent, so not every carton meets that bar.
Both point the same way in practice: frozen cream is for cooking. NDSU notes that cream that has been frozen “will not whip to the usual volume,” so use it in soups, sauces, casseroles and baking, not for whipped cream. Freeze it before its date, thaw it in the refrigerator, stir or blend it if it has separated, use it soon, and don't refreeze it. Whipped cream is the exception: NDSU suggests freezing sweetened whipped cream in individual mounds on a tray, and FoodKeeper gives it 1–2 months frozen.
Whipped cream and coffee creamer
| Product | Refrigerator | Freezer |
|---|---|---|
| Whipped cream, sweetened | 1 day | 1–2 months |
| Whipped cream, aerosol can | 3–4 weeks from purchase | Not recommended |
| Coffee creamer, liquid refrigerated | 3 weeks from purchase | Not listed |
How to tell cream has gone bad
- A sour or off smell.
- Thick, lumpy or curdled texture in the carton, or white flecks when you pour it into hot coffee.
- Mold or discoloration anywhere, including around the spout.
- Time out of the fridge. FDA says not to leave perishables at room temperature for more than 2 hours, or 1 hour above 90°F. Cream left out longer goes in the trash whatever it smells like.
For the rest of the dairy case, see the shelf life chart, or turn a purchase date into a use-by day with the food expiration calculator.
Questions people ask
How long is heavy cream good after the expiration date?
There is no official number of days past the printed date. The date is the dairy's own quality estimate, and USDA's FoodKeeper counts from the day you buy the cream instead: 10 days in the fridge for heavy cream, and 1 month unopened for ultra-pasteurized whipping cream. If the cream has stayed at 40°F or below and is past its date, check it closely, and throw it out if it smells sour, has thickened or lumped, or you aren't sure.
How long is heavy whipping cream good after opening?
FoodKeeper gives ultra-pasteurized whipping cream 1 week in the refrigerator after opening, even though the sealed carton keeps about a month from purchase. Write the opening day on the carton so you know when the week is up. FoodKeeper doesn't list a separate opened time for regular pasteurized heavy cream, which only gets 10 days from purchase in the first place.
How long is half and half good after the expiration date?
USDA's FoodKeeper gives half-and-half 3 to 4 days in the refrigerator, counted from the day you buy it, which is often shorter than the date printed on the carton. FoodKeeper doesn't say how long it lasts past that printed date, and neither does any other USDA source we found. If it is past its date, smells sour or curdles in hot coffee, throw it out.
Can you freeze heavy cream?
Yes, for cooking. FoodKeeper gives heavy cream 3 to 4 months in the freezer, but lists freezing as not recommended for ultra-pasteurized whipping cream. NDSU Extension says frozen cream will not whip to its usual volume, so use thawed cream in soups, sauces and baking. Thaw it in the refrigerator, use it soon, and don't refreeze it.
Why does heavy cream have such a long expiration date?
Most likely because it is ultra-pasteurized. Federal rules define that as heating to at least 280°F for at least 2 seconds, which produces an extended shelf life under refrigeration. The extra time applies only while the carton is sealed: once opened, FoodKeeper gives ultra-pasteurized whipping cream 1 week.
Can heavy cream sit out overnight?
No. FDA's rule for perishable food is no more than 2 hours at room temperature, or 1 hour above 90°F. Cream left out overnight should be thrown away, even if it looks and smells normal.
