How long doesHummuslast in the fridge once opened?

The USDA rates 2 kinds of this separately

The USDA files 2 separate entries under this name — commercial (pasteurized, with preservatives) and traditional (no preservatives, not pasteurized) — and they do not keep for the same time: Hummus, traditional (no preservatives, not pasteurized) holds 7 days outside the freezer, Hummus, commercial (pasteurized, with preservatives) holds 3 months.

Why the freezer is not an option here

The USDA marks the freezer as not recommended for every one of the 2 kinds under this name, and for Hummus, commercial (pasteurized, with preservatives) the whole answer is 7 days in the refrigerator after opening. It is not a warning: food held at 0 °F stays safe, so a not-recommended is a verdict on what would come out of the freezer.

Every storage figure the USDA publishes for this item

The refrigerator is the only place the USDA gives this item a storage time, as it does for 64 of the 466 foods the USDA lists. The source also indexes it as commercial, pasteurized, preservatives and preservative.

Turning the range into a date

Each kind gets its own dated rows here, 3 rows across the 2 the USDA lists under this name, because a date is only worth printing against the window it belongs to.

Is this window about safety or about taste?

The answer at the top of this page reads 7 days in the fridge once opened. What decides that is the food and not the shelf the source files it on: Hummus, commercial (pasteurized, with preservatives) is cooked or ready to eat and still moist. 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 fridge 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. 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 Hummus, commercial (pasteurized, with preservatives) past its 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. 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?

Among the 25 items the USDA files under Deli & Prepared Foods, Hummus, commercial (pasteurized, with preservatives) ranks 2 by how long it keeps outside the freezer. Olives holds 18 months, Canadian bacon holds 80 days. Among the 340 foods the USDA also gives a refrigerator figure, it keeps longer than 77% of them.

Items that behave the same way

Every one of the 6 nearest items keeps the same or less, 5 days to 80 days against the 3 months of Hummus, commercial (pasteurized, with preservatives), which makes it the durable end of the cluster.

Products the USDA rates in the same places

No other product in the file is rated in exactly this set of places: refrigerator, refrigerator from the day of purchase and refrigerator after opening, and nothing else. That makes the shape of this record unique among the 466 products here, so the closest comparisons available are the entries that share most of it — Canadian bacon, Luncheon meat or poultry and Salami. Their windows are printed beside them below, and none of them is rated in quite the same way. Of the 8 shown, 1 keeps longer than this one.

Nothing carries this exact set of places, so these share most of it.

The rest of the Deli & Prepared Foods shelf

The USDA puts this product on the Deli & Prepared Foods shelf together with 24 others, and 1 of them keeps longer outside the freezer. The shelf runs from Olives at 18 months down to Pate at 2 days. Nearest this product by window are Canadian bacon, Commercial brand vacuum-packed dinners and Luncheon meat or poultry, which is the order the list below is printed in. Across the whole of Deli & Prepared Foods the same product ranks 2 of 25. The middle of the shelf is Fruit, cut, at 4 days.

If it has to keep longer than this

If it has to keep longer than 3 months, Deli & Prepared Foods offers 1 product that holds at least twice as long outside the freezer. The nearest step up is Olives at 18 months against this one's 3 months, and the rest are none beyond it. A short list like this one is itself the finding: the category has few longer options. In the other direction, 22 entries in the category keep half as long or less, Commercial brand vacuum-packed dinners and Luncheon meat or poultry among them.

The record this page is built from

The USDA publishes 2 separate rows under this name — records 181 and 183 — and this page carries all of them rather than picking one, because their windows differ. Between them they fill 3 of the nine storage slots with a time. Comparisons and the place in the category are computed for Hummus, commercial (pasteurized, with preservatives), which is the kind the plain name means here, chosen kind by kind rather than by the order the source happens to list them in. 1 slot is marked not recommended, which is an answer rather than a gap.

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.
