How Long Does Shrimp Last?

How long does raw shrimp last in the fridge?

Raw shrimp lasts 1-2 days in the fridge when stored at 40 degrees F or below. For longer fresh life, store shrimp on ice in a sealed container; place the container of ice on the bottom shelf of the fridge, and the lower temperature extends life by 1-2 days. Drain melted ice and replace as needed. Most shrimp sold in the US has been previously frozen and thawed for display; the 'fresh' shrimp from the seafood counter started its clock at the store's thawing time. If buying frozen shrimp, keep frozen until ready to use; thaw in the fridge overnight or in cold water for quick thawing. Shell-on shrimp lasts the same as shell-off; the shells don't significantly extend storage time. Head-on shrimp deteriorate faster than headless because the digestive enzymes in the head accelerate spoilage of the body meat.

How long does cooked shrimp last?

Cooked shrimp lasts 3-4 days in the fridge stored in airtight containers at 40 degrees F or below. Cool cooked shrimp to room temperature within 2 hours before refrigerating; the small size of shrimp means they cool quickly when spread in a single layer. Cooked shrimp in pasta, salads, or other dishes lasts 3-4 days. Cooked shrimp salad with mayo lasts 3-5 days. Boiled, grilled, or pan-seared shrimp all follow the same window. Avoid reheating cooked shrimp multiple times; quality declines and overcooking is easy with seafood. Eat cooked shrimp cold (in salads, pasta salads, or shrimp cocktail) or gently reheat just until warm to prevent rubbery texture.

How long does frozen shrimp last?

Frozen raw shrimp lasts 3-6 months at 0 degrees F for best quality (safe indefinitely). Frozen cooked shrimp lasts 2-3 months. The relatively short freezer life for shrimp comes from its high moisture content and delicate cellular structure; ice crystal damage during freezing can affect texture. To freeze raw shrimp at home: arrange in a single layer on a baking sheet, freeze for 1-2 hours until firm, then transfer to freezer bags or containers with air pressed out. The pre-freezing prevents shrimp from clumping together in the bag. Vacuum-sealed frozen shrimp lasts longer (6-9 months) due to the lack of oxygen slowing oxidation.

How can you tell when shrimp has gone bad?

Bad shrimp shows clear signs. Strong ammonia or fishy smell distinct from the mild ocean-fresh aroma indicates spoilage; fresh shrimp should smell barely noticeable or slightly briny. Slimy or sticky texture on raw shrimp indicates bacterial growth; fresh shrimp should feel slightly moist but firm. Gray, dull, or yellowish color on previously pearly-white or pink shrimp indicates oxidation. Cooked shrimp should be uniformly pink-orange; pale coloring suggests spoilage. Mushy texture in raw shrimp indicates breakdown. Black spots on the shell (melanosis) are an early sign of decline but don't necessarily mean spoilage; if the shrimp smells fine, you can use it. Trust your nose; spoiled shrimp can cause severe food poisoning. When in doubt, throw it out; shellfish food poisoning can be particularly dangerous.
