How long doesCheesecakelast in the fridge once opened?

Freezing changes the unit, not just the number

Here the freezer does not so much extend the answer as replace it. 7 days in the opened fridge becomes 6 months in the freezer: 26 times longer, and days turning into months. The freezer from the day of purchase figure alone spans 3 months to 6 months, a factor of two.

Every storage figure the USDA publishes for this item

The USDA rates this item cold or frozen and never at room temperature: no pantry figure exists for it, as for 222 of the 466 foods in the data that get no pantry time at all. The source also indexes it as cake and cheese.

• In the freezer3 months to 6 months
• Once opened · in the fridge5 days to 7 days

Turning the range into a date

Two clocks run on this item: one from the day it went into storage and one from the day the seal broke. Both are listed below, 2 rows in all.

Is this window about safety or about taste?

The answer at the top of this page reads 5 days to 7 days in the fridge once opened. What decides that is the food and not the shelf the source files it on: Cheesecake is an animal food, or made with one. Past it, throw it out rather than taste it: a perishable food can carry enough bacteria to make you ill while it still looks and smells fine.

The figure in the freezer here is 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. Held at 0 °F food stays safe for as long as it stays frozen, which is why a freezer figure counts as quality on this site whatever the food is. Every figure assumes the food was sound when you stored it, that your refrigerator holds 40 °F or below and your freezer 0 °F or below, and that the package was handled normally.

It is past the date. Now what?

Say the calculator above puts Cheesecake past its 5 days to 7 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 FoodKeeper entry this page is built from prints storage times and nothing else, so anything past them here is USDA and FSIS guidance rather than a figure from the source. The whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.

Is that a long time?

3 items in the Baked Goods list keep exactly as long as this item, 7 days, so they all share place 42 of 52 rather than being put in an order the data does not support. Among the 340 foods the USDA also gives a refrigerator figure, it keeps longer than 39% of them.

Items that behave the same way

The 6 items below are the closest match to this item by storage behavior, running 4 days to 10 days and bracketing its 7 days.

Products the USDA rates in the same places

Only 1 other product in the whole file carries the same set of rated places as this one, freezer from the day of purchase and refrigerator after opening: Dairy filled eclairs. That is 1 product out of 466, which makes this a rare shape of record rather than a common one, and it is worth knowing that the comparison below is drawn from a very small group. Of the ones shown, none keeps longer than this one does. The longest-keeping of them is Dairy filled eclairs at 3 days.

Closest by shape, but not an exact match — they share most of these places, not all of them.

The rest of the Bakery shelf

The USDA puts this product on the Bakery shelf together with 15 others, and 6 of them keep longer outside the freezer. The shelf runs from Pastries at 14 months down to Macaroons at 2 days. Nearest this product by window are Fruit pies, Muffin and Quiche, which is the order the list below is printed in. The order counts the longest window outside the freezer, so this item sits here at 7 days rather than at the 5 days in the fridge once opened its own answer prints.

If it has to keep longer than this

If it has to keep longer than 7 days, the Baked Goods aisle gives 39 products that hold at least twice as long outside the freezer. The smallest step up is Commercial bread products at 3 weeks against this one's 7 days; after it come Garlic, Cookies and Bread. They are printed below in the order the step gets bigger, not alphabetically. In the other direction, 6 entries in the category keep half as long or less, Dairy filled eclairs and Cinnamon rolls among them.

The record this page is built from

This page is built from a single FoodKeeper row, record 198 — the source’s own number for it, not a position — one of the 661 rows in the snapshot. That row fills 2 of the nine storage slots with a time, and the source prints its binding figure in days, so the window at the top of this page is the source's own number untouched. The same record answers to cake and cheese in the source's own index. It is filed under Bakery inside Baked Goods, which is where every shelf comparison on this page comes from.

Where these numbers come from

Every range on this page is published by the USDA FoodKeeper and reproduced unchanged. The multipliers, the rankings, the percentages and the dates are ours, computed from those ranges. Where the source gives a span such as 3 to 5 weeks, comparisons use the upper figure, and the full span is always printed.

Rankings cover only the items the USDA gives a usable figure for, and identical ranges share a place rather than being ordered arbitrarily. Neighbors are chosen by nearest storage time within the same category, never alphabetically: two foods filed next to each other by name usually have nothing to do with each other. The freezer is excluded from ranking because it flattens almost everything.

Where the USDA lists several kinds under one name, they share one page here and every kind keeps its own windows: the source prints them as separate rows, and a page that merged them would be inventing a figure the source never published. Comparisons and the place in the category are computed for the kind the plain name means — the shell egg for eggs, the can for tuna — which is settled name by name rather than by the order the source lists its rows in, and the page names it. Where the plain name means no single kind, the page prints no single figure at all and lists the kinds instead.
