How long does Mung bean last in the fridge?
Turning the range into a date
Mung bean (dry, food-grade bags) keeps 1 year in the fridge. Each kind gets its own dated rows here, 5 rows across the 3 the USDA lists under this name, because a date is only worth printing against the window it belongs to.

The USDA rates 3 kinds of this separately
Mung bean, sprouts keeps 4 weeks, which is shorter than the window this page answers with. The USDA files 3 separate entries under this name — sprouts, dry, food-grade bags and dry, vacuum-sealed — and they do not keep for the same time: Mung bean, sprouts holds 4 weeks to 6 weeks outside the freezer, Mung bean, dry, vacuum-sealed holds 8 years to 10 years.
The freezer changes nothing here
The USDA gives this item the same window either way: 1 year in the refrigerator and 1 year in the freezer. Freezing is not a mistake here, it simply buys nothing, and the refrigerator is the cheaper place to keep it. On the same shelf it sits 7 of 23, between Peas, dried split at 1 year and Bulgur at 12 months. Sprouted mung beans, sprouted mung bean and sprout are the same food in the source list.
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 sprout, mungbean, sprouts and dry.

What the USDA adds in words
The USDA attaches 2 handling notes to this item, reproduced below word for word. None of them is a storage time: they qualify the figures above rather than replacing them. 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.
Mung bean, sprouts, in the refrigerator. Never refrigerate wet sprouts. Transfer to a plastic bag or use a glass or plastic container.
Mung bean, dry, food-grade bags, in the pantry. Keep the beans in an airtight container as it’s imperative that they remain dry.
Can you freeze mung bean?
Yes. The USDA gives mung bean (dry, food-grade bags) 1 year in the freezer, and held at 0 °F food stays safe beyond that: the figure is about quality. Freeze it well wrapped while it is still well inside its fridge window: the freezer keeps quality, it does not restore it.
How to tell if mung bean has gone bad
Go by the date first: mung bean keeps 1 year in the fridge. A sour or off smell, mold, slime or an odd color mean it goes out. The bacteria that make people sick change none of these, so past its window it goes out even if it seems fine. Never taste to test.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 1 year in the fridge. What decides that is the food and not the shelf the source files it on: Mung bean, dry, food-grade bags is acid, dry, sweet, alcoholic or pure fat. Past it, whether it has gone bad is yours to judge by look and smell: this window rates quality, not the day it turns hazardous.
The figure in the fridge here is a safety limit. 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 Mung bean, dry, food-grade bags past its 1 year in the fridge window. Past that the calendar stops deciding and the food itself does. Insects or webbing in the package, a musty or rancid smell, or clumping that says damp got in mean it goes out whatever the date says.
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 whole rule, including the cases the source does not cover, is set out under what to do when the date has passed.
Items that behave the same way
Every one of the 6 nearest items keeps the same or less, 3 months to 1 year against the 1 year of Mung bean, dry, food-grade bags, which makes it the durable end of the cluster.
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.
