Question by question

Caviar shelf life, answered

How long does caviar last in the fridge?

2 days at 4°C (40°F) or colder (opened). Count from the day it was cooked, opened or bought.

How long does caviar last in the freezer?

Not recommended. Freezing caviar is not recommended; texture breaks down or the result is unsafe to rely on.

How long does caviar 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 caviar last after opening?

2 days in the fridge once opened. The printed date stops applying the moment you break the seal.

How long does unopened caviar last?

1–4 weeks in the fridge, if the seal is intact and it is stored as the label says.

How long is caviar good for past the expiration date?

FoodKeeper gives unopened caviar 1–4 weeks 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 caviar is bad?

Strong fishy, sour or ammonia odour. Fresh seafood smells of the sea. Mushy flesh that does not spring back, or a milky slime. Dull, grey or yellowing flesh; dark edges.

How long can caviar sit out?

2 hours at room temperature, 1 hour on a hot day above 32°C (90°F). Overnight is always too long.

Reheating

How to reheat caviar safely

1

Reheat to 74°C (165°F)

Check the thickest part with a food thermometer; it should be steaming hot all the way through.

2

Only once

Reheat just the portion you will eat. Each cool-and-reheat cycle gives bacteria another chance.

3

Cover and stir

In the microwave, cover the dish and stir halfway so there are no cold spots.

4

From the freezer

Thaw in the fridge first, or reheat straight from frozen and allow extra time.

The 2-hour rule

Caviar left out overnight

Caviar 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.
