How to Store Raw Shrimp in Refrigerator

Fresh shrimp is delicious but highly perishable — it deteriorates even faster than most fish. Knowing how to store raw shrimp in the refrigerator correctly is essential for both food safety and quality. Here's the complete guide.

Fresh vs. Previously Frozen Shrimp

Most "fresh" shrimp at the grocery store has actually been previously frozen and thawed. This is important because previously frozen shrimp should never be refrozen — it significantly degrades texture and safety. Check with your fishmonger or look for "previously frozen" labeling.

How to Store Raw Shrimp in the Refrigerator

1. Store on ice for maximum freshness — Place shrimp in a ComSaf Airtight Container filled with ice. Set the shrimp on top of the ice (in their bag or a colander placed over the ice so they don't sit in meltwater). Cover and refrigerate on the bottom shelf.
2. Standard storage — If not using ice, keep shrimp in their original packaging or transfer to a sealed SPLF Reusable Bag with air squeezed out. Place on a plate on the bottom shelf.
3. Always store on the bottom shelf — Shrimp juices can contaminate other foods if stored above them.
4. Cook within 1–2 days — Fresh or thawed shrimp has a very short refrigerator window.

How Long Does Raw Shrimp Last in the Refrigerator?

• Fresh raw shrimp (on ice): 1–2 days
• Fresh raw shrimp (standard fridge): 1–2 days
• Previously frozen, thawed shrimp: 1–2 days (do not refreeze)
• Frozen raw shrimp: 3–6 months

How to Freeze Raw Shrimp

If your shrimp has never been frozen, you can freeze it for longer storage. Peel and devein if desired, pat dry, and store in a FoodSaver Vacuum Sealer Bag for best results. Alternatively, place in a SPLF Reusable Freezer Bag with air squeezed out. Label with the date. Thaw in the refrigerator overnight or under cold running water.

Signs Raw Shrimp Has Gone Bad

• Strong ammonia or "off" fishy smell (fresh shrimp smells mildly of the sea)
• Slimy texture
• Black spots on the shell (some discoloration is normal, but widespread black spots indicate spoilage)
• Yellowing or discolored flesh
• Past the use-by date
