Discard it after the expiration date.
⚠️ Seafood spoils quickly and can cause severe food poisoning if consumed past its prime.
Fridge
32°F (0°C)
Store in original packaging on a bed of ice
Consistent cold storage is essential for food safety. A refrigerator thermometer (Amazon) helps monitor refrigerator temperature and ensures food stays at safe levels (40°F or below).

30 days
Foul smell, slimy texture, mold growth
Proper packaging helps prevent freezer burn and contamination. Using freezer-safe storage bags (Amazon) can help preserve food quality during freezer storage.

Caviar is a perishable product that degrades over time due to exposure to air and light. As caviar ages, its texture may become softer, flavor may diminish, and it may develop off-putting odors. While caviar may still be safe to eat past its expiration date if properly stored, the best quality is typically enjoyed within a few weeks of purchase.
To determine if caviar has gone bad, check for any off-putting fishy or sour smell. Visually inspect the caviar for any signs of mold, discoloration, or sliminess. Fresh caviar should have a firm texture and individual eggs should be separate, not mushy or clumped together.
Consuming raw or undercooked caviar poses a risk of foodborne illnesses such as salmonella and listeria. To prevent these risks, always ensure that caviar is properly sourced from reputable suppliers, stored at proper temperatures, and consumed within the recommended timeframe. High-risk scenarios include leaving caviar at room temperature for extended periods or consuming expired caviar.
To maintain the quality of caviar, store it in the coldest part of the refrigerator, preferably between 28-32°F (-2 to 0°C). Keep the caviar tin tightly sealed to prevent air exposure and avoid placing it in the freezer, as this can alter the texture. Serve caviar on a bed of ice to maintain its freshness during gatherings.
Caviar has been considered a luxury food for centuries, with historical records of its consumption dating back to ancient Greece and Rome. It holds cultural significance as a symbol of wealth and sophistication in many societies. Interesting trivia includes the classification of caviar based on the fish species, such as Beluga, Osetra, and Sevruga.
Refrigeration helps extend the shelf life of Caviar by maintaining a consistent cold temperature, slowing down bacterial growth. Store Caviar in the coldest part of the fridge, ideally between 32-39°F (0-4°C), in its original sealed container or tightly wrapped with plastic wrap to prevent exposure to air.
Caviar should not be consumed if left at room temperature for 2 hours or more. Bacterial growth accelerates at room temperature, increasing the risk of foodborne illness. Discard any Caviar that has been left out for an extended period to prioritize food safety.
Once opened, consume refrigerated Caviar within 2-3 days for the best quality and safety. Ensure to seal the container tightly with its original lid or plastic wrap after each use to prevent air exposure and contamination, which can lead to spoilage.
