How long does Bison last?
- Ground1 day to 2 days
- Whole3 days to 5 days
Turning the range into a date
Each kind gets its own dated rows here, 4 rows across the 2 the USDA lists under this name, because a date is only worth printing against the window it belongs to.
Bison, whole
- In the freezerUse by6 months to 9 months after the day you stored it
- In the fridgeUse by3 days to 5 days after the day you stored it
Bison, ground
- In the freezerUse by3 months to 4 months after the day you stored it
- In the fridgeUse by1 day to 2 days after the day you stored it
The USDA rates 2 kinds of this separately
The USDA files 2 separate entries under this name — whole and ground — and they do not keep for the same time: Bison, ground holds 1 day to 2 days outside the freezer, Bison, whole holds 3 days to 5 days.
The shortest of these, Bison, ground at 2 days, is a safety limit, and past it the food goes out untasted.
Every storage figure the USDA publishes for this item
The USDA rates this item cold or frozen and never at room temperature: no pantry figure exists for it, as for 222 of the 466 foods in the data that get no pantry time at all. The source also indexes it as whole and ground.
Bison, whole
- In the freezer6 months to 9 months
- In the fridge3 days to 5 days
Bison, ground
- In the freezer3 months to 4 months
- In the fridge1 day to 2 days
Can you freeze bison?
Yes. The USDA gives bison (whole) 6–9 months in the freezer, and held at 0 °F food stays safe beyond that: the figure is about quality. Wrap it airtight or overwrap the store tray: freezer burn dries the surface but does not make meat unsafe.
How to tell if bison has gone bad
Go by the windows listed above first. Signs are a sour or off smell, a sticky or slimy surface and graying or greenish spots. Dangerous bacteria give no such signs, so past the window it goes out even if it seems fine. Cook ground meat to 160 °F, poultry to 165 °F, and steaks, chops and roasts to 145 °F.

It is past the date. Now what?
Say the shortest window under this name — Bison, ground at 1 day to 2 days in the fridge — has run out, 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.
What decides that is the food and not the shelf the source files it on: Bison, ground is an animal food, or made with one. 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. Freezing stops the clock but does not turn it back: food already past its window is not rescued by putting it in the freezer. 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
Bison carries no single window to compare — its 2 kinds each keep their own — so these 6 are simply what the USDA rates on the same shelf, shortest first: Sausage at 2 days through Chorizo at 2 days.
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.

No one of the 2 is the kind the plain name means, so this page prints no single figure: the kinds are listed with their own windows and you pick yours.
