How long does Rhubarb last in the fridge?
Turning the range into a date
Rhubarb keeps 3–7 days in the fridge from purchase. One row, one deadline: 7 days in the refrigerator from the day of purchase, counted from the day it went in rather than the day it was made.

A short window, and what shortens it further
This item is one of the short-lived entries in the data: 7 days outside the freezer, position 49 of 89 in the Produce list. At that scale a day of delay is a large share of the whole window, which is why the figure is printed as a range rather than an average. On the same shelf it sits 49 of 89, between Mushrooms at 7 days and Taro at 7 days.

Can you freeze rhubarb?
The USDA prints no freezer time for rhubarb. Frozen at 0 °F any food stays safe; whether it is still good after thawing is a matter of quality. Keep the fridge at 40 °F or below and the freezer at 0 °F.
How to tell if rhubarb has gone bad
Go by the date first: rhubarb keeps 3–7 days in the fridge. Mold, slime, a sour smell or soft dark spots mean it goes out; firm produce can be saved by cutting 1 inch around a small moldy spot, soft produce cannot. Refrigerate cut or peeled produce within 2 hours.

Is it still safe to eat, or just past its best?
The answer at the top of this page reads 3 days to 7 days in the fridge. What decides that is the food and not the shelf the source files it on: Rhubarb is raw and whole. 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.
It is past the date. Now what?
Say the calculator above puts Rhubarb past its 3 days to 7 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 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
All 6 of the 6 items nearest this item keep exactly as long as it does, 7 days, so the ranking around it is a tie rather than an order.
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.
