Shrimp is one of the favorite commodities consumed by many people. Before you buy shrimp, you should know what fresh shrimp looks like so you don’t end up with the wrong kind and put your health at risk. There are various tips for choosing fresh shrimp and distinguishing between fresh and spoiled shrimp. Find out more below!.
As a seafood lover, I eat a lot of shrimp. I love tossing plump, juicy shrimp into stir fries, simmering them in seafood stews, and grilling them up for shrimp kabobs. But before I can cook up any shrimp dish, I need to start with high-quality, fresh raw shrimp.
When buying raw shrimp at the store or market it can be tricky to tell if you’re getting the good stuff. Shrimp can easily spoil, so it’s important to pick out shrimp that is fresh and safe to eat. The best indicator? Checking the color!
Follow this complete color guide to picking out raw shrimp at peak freshness. I’ll explain what hue you should look for, what colors to avoid and how color relates to shrimp quality. Read on for pro tips to ensure you select delicious fresh-from-the-sea shrimp every time.
The Ideal Raw Shrimp Color – Translucent Pink
Freshly caught raw shrimp sport a distinctive translucent pink hue. You should see the pinkish flesh showing through a thin, pale shell. The shrimp should not appear too opaque.
This pale pink color indicates the shrimp was recently caught and properly handled. As shrimp ages, the flesh will become more opaque and take on a whiter, grayish color. Stay away from shrimp with an overly milky or chalky look.
When cooked, fresh pink shrimp will turn a deeper, richer reddish-pink. This vibrant coral color shows the shrimp is at optimal freshness for eating.
What Other Natural Shrimp Colors Mean
While translucent pink is ideal, some other natural shell colors can indicate high quality:
-
Spotted brown shrimp shells show maturity. Spots don’t affect quality.
-
Green or blue hues come from aquatic plant pigments. Totally normal and safe.
-
Darker shell tips can indicate warmer habitat waters. Meat remains fine to eat when fresh.
The key is making sure these naturally darker shrimp still have brightly colored, semi-transparent flesh showing through.
Colors to Avoid in Raw Shrimp
Certain colors act as warning signs that raw shrimp is past its prime:
-
Whitish flesh means the shrimp is old. The meat starts to oxidize and lose its natural pinkness.
-
Yellow, tan, or beige flesh is a bad sign. This likely means temperature abuse during storage.
-
Grayish, dull, or faded color indicates the shrimp is not freshly caught or properly stored.
-
Black/dark spots or streaks mean quality loss and spoilage. Don’t purchase these shrimp.
-
Bright red and very opaque shrimp may contain added dye. Natural shrimp is never bright red when raw.
If you see any of these colors dominating the visual appearance of raw shrimp, it’s best to pass it up.
What Makes Shrimp Change Color?
Now you know what to look for color-wise when buying raw shrimp. But what makes shrimp change from that ideal translucent pink hue during storage and handling? Here are the main factors:
1. Age
As shrimp naturally ages after being caught, enzymes start breaking down the flesh. This causes the color to fade and turn more opaque.
2. Temperature
Improper temperature during storage and transport is a major color-changer. Heat abuse turns shrimp tan or yellow. Cold abuse gives it a bleached appearance.
3. Bacteria
As bacteria grow on aging, temperature-abused shrimp, their waste products interact with proteins in the flesh, causing dullness.
4. Freezing
Repeated freezing/thawing cycles degrade shrimp cell structure. This leads to protein denaturing and a whitish, opaque color.
5. Additives
Some unethical sellers add dyes and chemicals to old shrimp to mask color changes. Watch for unnaturally bright hues.
The takeaway is to select shrimp with the lively translucent pink color that signals freshness and proper handling.
Quick Ways to Check Shrimp Freshness
Shrimp color gives you great insight into freshness at a glance, but don’t stop there. Here are a few other quick checks to perform:
-
Give shrimp a sniff – it should have a neutral, briny scent, not a strong fishy odor.
-
Look at texture – raw shrimp should be firm with tight, plump meat. Avoid mushy or slimy.
-
Check legs and antennae – they should be intact, not broken or missing.
-
Inspect the shells – they should cling tightly to the shrimp meat.
-
Check for dark veins – minimize vein visibility by buying smaller shrimp sizes.
If you see any flaws like strong odors, soft texture, or dark spotting, pass on purchasing the shrimp. Remember, when in doubt, it’s best to throw it out.
Storing Shrimp to Maintain Color and Freshness
Once you’ve picked out high-quality raw shrimp to take home, be sure to store it properly to maintain that just-caught color and flavor:
-
Keep raw shrimp chilled at 32-40°F, coldest part of refrigerator
-
Place in moisture-proof container or resealable plastic bag
-
Avoid overcrowding shrimp, keep single layer
-
Use ice packs/ice to keep extra cold
-
Consume within 1-2 days of purchasing for peak quality
-
Handle cleaned and cooked shrimp carefully to prevent cross contamination
Proper cold storage preserves texture and minimizes any color fading or spoilage. Follow these tips for delicious shrimp no matter what dish you have in mind.
Cooking Vibrant Pink Shrimp
When starting with high-quality raw shrimp with that beautiful translucent pink color, it’s hard to go wrong with any cooking method. Here are some of my favorite ways to enjoy fresh-from-the-sea shrimp:
-
Quick saute with lemon, garlic, and white wine
-
Grilled shrimp skewers brushed with chili sauce
-
Air fryer coconut shrimp with mango dipping sauce
-

No matter how you cook it, ultra-fresh shrimp keeps its signature pop of color on the plate, letting you know it’s at peak quality before you take that first delicious bite.
So next time you shop for raw shrimp, remember to consult this color guide. Seek out that natural translucent pink hue and avoid any washed-out or unnatural shades. With properly handled fresh shrimp, you can feel confident creating all kinds of vibrant, lip-smacking dishes at home. Happy shrimping!
Signs of Spoiled Shrimp
Having learned what fresh, high-quality shrimp looks like, it’s time to learn what spoiled shrimp looks like and how to tell them apart.
Signs of Fresh Shrimp
Fresh and high quality shrimp can be assessed based on color, texture, movement, and several other criteria.
The color of a shrimp reflects its freshness. Fresh shrimp should have a slightly transparent pink or gray color.
Fresh shrimp can also be assessed by their tails. The tail of fresh shrimp should be firm and tightly curved, not limp.
In addition to the overall color of the shrimp, the color of the gills also indicates its freshness. Fresh and healthy shrimp should have bright red gills.
Another characteristic of fresh shrimp is a full and intact gut. A shrimp with a full gut has a healthy digestive system and is taking in enough nutrients from its food.
From the head to the tail, a fresh shrimp should have a body that is whole and not missing or damaged organs. The shrimp shell should also appear shiny, smooth, and free from cracks.
