How long doBagged greenslast in the fridge once opened?
Why the freezer is not an option here
The USDA marks the freezer as not recommended for this item, so the answer comes from the refrigerator after opening figure: 2 days. The source fills 2 of its fields outside the freezer here, and every one of them is printed below. 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.

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.
In the refrigerator. Unopened product will last 3 - 5 days after date on bag; after opening it will last 2 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 2 days in the fridge once opened. What decides that is the food and not the shelf the source files it on: Bagged greens, leaf, spinach, lettuce, etc. is cut and ready to eat. 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.
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 Bagged greens, leaf, spinach, lettuce, etc. past its 2 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?
9 items in the Produce list keep exactly as long as this item, 5 days, so they all share place 66 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 30% 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 6 days and bracketing its 5 days.
Products the USDA rates in the same places
No other product in the file is rated in exactly this set of places: refrigerator 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 — Apricots, Peaches and Plantains. 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. The longest-keeping of them is Kiwi fruit at 6 days.
Nothing carries this exact set of places, so these share most of it.

The rest of the Fresh Vegetables shelf
The USDA puts this product on the Fresh Vegetables shelf together with 58 others, and 46 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. Across the whole of Produce the same product ranks 66 of 89. The middle of the shelf is Swiss chard, at 2 weeks.

If it has to keep longer than this
If it has to keep longer than 5 days, the Produce aisle gives 47 products that hold at least twice as long outside the freezer. The smallest step up is Basil at 10 days against this one's 5 days; after it come Bean sprouts, Cherry tomatoes and Blueberries. They are printed below in the order the step gets bigger, not alphabetically. In the other direction, 1 entry in the category keeps half as long or less, Corn on the cob 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 415 — 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. 1 slot is marked not recommended, which is an answer rather than a gap. The record carries 1 handling note, quoted on this page word for word.
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.
