Turning the range into a date

Coconut milk keeps 7–10 days in the fridge once opened. Each kind gets its own dated rows here, 4 rows across the 2 the USDA lists under this name, because a date is only worth printing against the window it belongs to.

The USDA rates 2 kinds of this separately

Coconut milk, canned keeps 4 days, which is shorter than the window this page answers with. The USDA files 2 separate entries under this name — USDA record 429 and canned — and they do not keep for the same time: Coconut milk holds 7 days to 10 days outside the freezer, Coconut milk, canned holds 2 years to 5 years.

A short window, and what shortens it further

Coconut milk is one of the short-lived entries in the data: 10 days outside the freezer, position 22 of 31 in the Dairy Products & Eggs list. At that scale a day of delay is a large share of the whole window, which is why the figure is printed as a range rather than an average. On the same shelf it sits 22 of 31, between Rice milk at 10 days and Quark, fresh cheese at 10 days.

Every storage figure the USDA publishes for this item

All three places the USDA recognizes are rated here — pantry, refrigerator and freezer — which only 65 of the 466 foods in the data manage. The source also indexes it as canned and can.

Where the USDA answers in words instead of days

1 of the nine slots the USDA keeps for this item holds an answer that is not a number, and an answer in words is still an answer: in the fridge it answers with the package date rather than a number, and the use-by date printed on that particular package is the figure to go by.

What the USDA adds in words

The USDA attaches 1 handling note to this item, reproduced below word for word. It is not a storage time: it qualifies the figure above rather than replacing it. These are the source's own sentences, not ours, and they are the part of the FoodKeeper record that a table of durations cannot carry.

Coconut milk, in the refrigerator. Keep refrigerated.

Can you freeze coconut milk?

Some kinds, yes. The USDA gives coconut milk (canned) 3 months in the freezer; held at 0 °F food stays safe beyond that. For coconut milk, the kind this page answers for, it gives no freezer figure. Dairy can separate or turn grainy once thawed, so frozen it is better cooked with than eaten as it was.

How to tell if coconut milk has gone bad

Go by the date first: coconut milk keeps 7–10 days in the fridge once opened. Sour or off smell, lumps in milk or cream, and mold mean it goes out. On hard cheese, cut away 1 inch around a moldy spot; soft cheese with mold goes out whole.

Sources: USDA FSIS: the danger zone USDA FSIS: freezing and food safety USDA FSIS: molds on food FDA: are you storing food safely FoodSafety.gov: the FoodKeeper app.

Is it still safe to eat, or just past its best?

The answer at the top of this page reads 7 days to 10 days in the fridge once opened. What decides that is the food: the source files Coconut milk under Dairy Products & Eggs, a heading it keeps for perishable food. Past it, it is not safe to eat: throw it out without tasting, because bacteria build up while food still looks and smells fine.

The figures in the freezer and in the pantry here are a quality window. The same page carries windows of more than one kind, so which sentence applies depends on which row you are reading, not on the food.

It is past the date. Now what?

Say the calculator above puts Coconut milk past its 7 days to 10 days in the fridge once opened window, or the container sat out on the counter overnight. Throw the container out without tasting it, and count any hours it already spent out of the refrigerator as part of that window rather than on top of it.

The USDA's limit for perishable food standing at room temperature is 2 hours, or 1 hour when the kitchen is above 90 °F, and that clock runs whatever the storage figure says. Freezing stops the clock but does not turn it back: food already past its window is not rescued by putting it in the freezer. The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.

Where these numbers come from

Every storage time on this page is the USDA’s own published figure from the FoodKeeper data, one of the 9 it keeps per food, reproduced unchanged and never an estimate of ours. Where the USDA lists several kinds under one name, each kind keeps its own windows, and the page names the kind its answer is for. The dates and multipliers are ours, computed from those ranges.
