Fridge
32°F (0°C)
Store in airtight container with ice packs
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).
2 days
90 days
Unpleasant fishy odor, slimy texture, discoloration
Proper packaging helps prevent freezer burn and contamination. Using freezer-safe storage bags (Amazon) can help preserve food quality during freezer storage.

Cooked shrimp, prawns
Fresh raw shrimp should be consumed within 1-2 days of purchase for optimal quality. Over time, shrimp can degrade in texture and flavor as enzymes break down proteins and fats. While the expiration date indicates safety, the best quality is usually within the first few days of purchase. Freezing can extend the shelf life for several months.
To check if raw shrimp has gone bad, look for a slimy texture, discoloration or dark spots on the surface, and a strong fishy or ammonia-like smell. Fresh shrimp should have a firm texture, a translucent appearance, and a mild oceanic scent. If you notice any of these signs, it's best to discard the shrimp to avoid foodborne illness.
Consuming raw shrimp poses risks of bacterial contamination, particularly from Vibrio species such as Vibrio parahaemolyticus and Vibrio vulnificus. To reduce the risk of foodborne illness, always ensure proper cooking to an internal temperature of at least 145°F (63°C) and avoid cross-contamination by keeping raw shrimp separate from ready-to-eat foods. High-risk scenarios include leaving raw shrimp at room temperature for extended periods and consuming undercooked shrimp.
For optimal storage, keep raw shrimp refrigerated at temperatures below 40°F (4°C) in airtight containers or sealed bags to prevent odor transfer. To maintain freshness, place a layer of ice on top of the shrimp and drain any excess water regularly. Avoid refreezing thawed shrimp and use within a few months for best quality. Marinating shrimp in citrus juice or vinegar can help reduce bacterial risks.
Shrimp has a rich cultural history, with evidence of shrimp consumption dating back thousands of years. In many cultures, shrimp symbolize happiness, abundance, and good fortune. In some regions, shrimp are considered a delicacy reserved for special occasions or festive celebrations. Shrimp are also a versatile ingredient used in a wide range of traditional dishes worldwide.
If Shrimp Fresh Raw has been at room temperature for 2 hours, it's best to discard it. Seafood is perishable and can quickly develop harmful bacteria at room temperature, increasing the risk of foodborne illness.
Once opened, Shrimp Fresh Raw should be consumed within 1-2 days for optimal freshness and safety. Ensure it's tightly sealed in a container to minimize exposure to air and odors in the fridge.
Yes, the type of container can impact the shelf life of Shrimp Fresh Raw. It's best to store seafood in airtight containers to prevent exposure to air and moisture, which can accelerate spoilage. Consider using glass or BPA-free plastic containers for optimal freshness.
