7–10 days at 4°C (40°F) or colder (opened). Count from the day it was cooked, opened or bought.
How long does coconut milk last in the freezer?
Not listed. FoodKeeper gives no freezer time for coconut milk.
How long does coconut milk last at room temperature?
No more than 2 hours, or 1 hour above 32°C (90°F). Perishable food left out longer should be thrown away.
How long does coconut milk last after opening?
7–10 days in the fridge once opened. The printed date stops applying the moment you break the seal.
How long does unopened coconut milk last?
Use-by date in the fridge, if the seal is intact and it is stored as the label says.
How long is coconut milk good for past the expiration date?
FoodKeeper gives unopened coconut milk use-by date in the fridge, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
How can you tell if coconut milk is bad?
Sour or cheesy smell when it should be clean and mild. Lumps, curdling or a thick, slimy body. Yellowing or a pink, green or grey tinge.
How long can coconut milk sit out?
2 hours at room temperature, 1 hour on a hot day above 32°C (90°F). Overnight is always too long.

Coconut milk left out overnight
Coconut milk left at room temperature for more than 2 hours (1 hour above 90°F / 32°C) should be thrown away. Bacteria multiply fastest between 40°F and 140°F, and reheating does not remove every toxin they make.
Bacteria multiply fastest between 4 °C and 60 °C (40–140 °F).
