How long does half and half last in the fridge?
USDA puts half and half at 3–4 days in the fridge — shorter than any other cream on the shelf, so buy the small carton and keep it off the door.

Can it sit out?
Half and half is perishable — the FSIS 2-hour rule applies.
Perishable food left at room temperature for more than 2 hours should be thrown out — 1 hour if it’s 90°F or hotter (a picnic, a hot car, a summer kitchen).
How to tell if half and half has gone bad
- Coffee that goes speckled instead of an even tan
- A sour smell at the carton spout
- A thick, clinging pour
- A yellow or grayish cast to the white
When in doubt, throw it out.
The freezer holds it 4 months, but it thaws grainy — send thawed half and half into a soup or a pan sauce, never into the mug.
