Why the freezer is not an option here

The USDA marks the freezer as not recommended for this item, so the whole answer is a single field: 4 days to 6 days in the refrigerator from the day of purchase. 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. Within Produce it is filed under Fresh Vegetables.

Turning the range into a date

One row, one deadline: 6 days in the refrigerator from the day of purchase, counted from the day it went in rather than the day it was made.

Is this window about safety or about taste?

The answer at the top of this page reads 4 days to 6 days in the fridge. What decides that is the food and not the shelf the source files it on: Cucumbers is raw and whole. Past it, judge it by look and smell: this window rates how good the food will be, not the day it becomes a hazard.

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 Cucumbers past its 4 days to 6 days in the fridge window. Past that the calendar stops deciding and the food itself does. Mold, a slimy or sticky surface, soft or darkened spots, or a sour smell mean it goes out whatever the date 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?

2 items in the Produce list keep exactly as long as this item, 6 days, so they all share place 64 of 89 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 38% of them.

Items that behave the same way

The 6 items below are the closest match to this item by storage behavior, running 5 days to 7 days and bracketing its 6 days.

Products the USDA rates in the same places

14 other products are rated in exactly these places — refrigerator from the day of purchase — out of the 466 in the file, so this is an uncommon shape of record. The nearest of them by keeping time are Rhubarb, Fresh clams and Bean sprouts. They are listed below with their own answers, closest first, which is why this list differs from the one on their pages. Of the 8 shown, 8 keep longer than this one. The longest-keeping of them is Cream cheese at 2 weeks.

The rest of the Fresh Vegetables shelf

The USDA puts this product on the Fresh Vegetables shelf together with 58 others, and 45 of them keep longer outside the freezer. The shelf runs from Kimchi at 12 months down to Corn on the cob at 2 days. Nearest this product by window are Beans and peas, Broccoli and broccoli raab and Brussels sprouts, 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 6 days rather than at the 4 days sealed in the fridge its own answer prints.

If it has to keep longer than this

If it has to keep longer than 6 days, the Produce aisle gives 44 products that hold at least twice as long outside the freezer. The smallest step up is Blueberries at 2 weeks against this one's 6 days; after it come Melons, Artichokes and Bamboo shoots. They are printed below in the order the step gets bigger, not alphabetically. In the other direction, 8 entries in the category keep half as long or less, Bananas and Bok choy among them. The largest step the category offers is Coconut at 1 year.

The record this page is built from

This page is built from a single FoodKeeper row, record 283 — the source’s own number for it, not a position — one of the 661 rows in the snapshot. That row fills 1 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. 1 slot is marked not recommended, which is an answer rather than a gap. It is filed under Fresh Vegetables inside Produce, 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.
