You might assume cooked shrimp lasts a long time in the fridge, but here's a surprise: cooked shrimp typically stays fresh for only 3 to 4 days. After that, even if it looks fine, it can start to harbor dangerous bacteria.
Imagine whipping up a big batch of shrimp tacos for a party, only to wonder a few days later—is it still safe to eat? That uncertainty can be risky. The reality is, the shelf life of cooked shrimp varies based on factors like storage temperature, how it was cooked, and how quickly it was refrigerated. Keep reading to learn how to keep your shrimp fresher for longer—and avoid a serious case of food poisoning.
Quick Answer: How Long Does Cooked Shrimp Last in the Fridge?
-
On average: 3–4 days
-
Fastest spoilage time: As soon as 2 days if improperly stored
-
Longest safe time: Up to 4 days when stored correctly at or below 40°F
What Affects How Long Cooked Shrimp Lasts?
1. Storage Temperature: The Critical Factor
Keeping cooked shrimp at 40°F (4°C) or lower is essential. Warmer temperatures encourage bacteria growth, which speeds up spoilage.
Pro Tip: Always refrigerate shrimp within 2 hours of cooking to maximize freshness
2. How Quickly It Was Refrigerated
Leaving shrimp out on the counter for too long is a major mistake. According to the USDA, perishable foods shouldn't sit out longer than 2 hours, or 1 hour if the room is above 90°F.
Quick Fix: Put cooked shrimp into shallow containers for faster cooling
3. Cooking Method and Seasonings
Simple boiled shrimp tends to spoil a bit faster than shrimp cooked with acidic marinades (like lemon or vinegar), which can slow bacterial growth slightly.
Tip: Acid-based seasonings may offer a tiny buffer, but still stick to the 3–4 day guideline
4. Quality Before Cooking
If the shrimp wasn't fresh before you cooked it, it won’t last as long after cooking. "Garbage in, garbage out" definitely applies here.
Tip: Always use shrimp that smells fresh (no ammonia smell) and has a firm texture.-
5. Airtight Storage
Oxygen exposure speeds up spoilage. Using airtight containers helps keep shrimp fresher longer.
Advice: Store shrimp in a clean, airtight container or heavy-duty freezer bag
Best-Case vs. Worst-Case Scenarios
If you refrigerate your shrimp promptly at the right temperature and use airtight storage, you can safely enjoy it for up to 4 days.
But if you leave cooked shrimp out for more than 2 hours or store it loosely covered in the fridge, it may spoil in just 2 days—or even sooner if your fridge runs warm.
Always trust your senses: if it smells off or feels slimy, toss it

-
Stovetop: Sauté gently over low heat for 1–2 minutes
