Hey there, fellow seafood lovers! I’ve been cooking shrimp for years, and one question keeps popping up – what’s that dark line running through our favorite crustacean? Let me break it down for you in simple terms, so you won’t have to worry next time you’re preparing your shrimp dinner.
What Actually Is That Dark Line?
Let’s get straight to the point – that dark line you see isn’t actually a vein! I know, mind-blowing right? Here’s what it really is:
- On the top: It’s the shrimp’s digestive tract (yes, containing waste material)
- On the bottom: It’s actually a nerve bundle (like our spinal cord)
The Top “Vein” – Let’s Talk About It
Okay, I’m gonna be real with you – the dark line on top is basically the shrimp’s poop chute. But before you freak out, here’s what you should know
What’s Actually In There?
The digestive tract contains
- Partially digested food
- Sand and debris
- Waste material from the shrimp’s diet (plankton, tiny sea creatures, etc.)
Is It Safe to Eat?
Here’s the good news – YES! It’s totally safe to eat as long as you cook your shrimp properly. Here’s why:
- Cooking kills any harmful bacteria
- The FDA doesn’t require deveining
- Millions of people eat undeveined shrimp without issues
To Devein or Not to Devein?
This is totally your call! Here’s what I think about both options:
Reasons to Devein:
- Better appearance (no dark line)
- Avoiding potential grittiness
- Personal preference
- Improved texture in larger shrimp
Reasons to Skip Deveining:
- Saves time
- Works fine for smaller shrimp
- No safety concerns
- Preserves natural flavor
How to Devein Shrimp – My Quick Guide
If you decide to devein, here’s my simple method:
-
Grab Your Tools:
- Sharp paring knife or deveining tool
- Clean cutting board
- Bowl of cold water
-
The Process:
1. Make a shallow cut along the back2. Lift out the dark tract3. Rinse under cold water4. Pat dry with paper towels
The Bottom “Vein” – What’s That About?
Now, let’s talk about that other dark line on the bottom of the shrimp. This one’s actually pretty interesting:
- It’s a nerve bundle
- Controls the shrimp’s basic functions
- More visible in certain species (like White Tiger shrimp)
- Completely harmless and doesn’t affect taste
Pro Tips from My Kitchen
After years of cooking shrimp, here are some tips I’ve learned:
-
Size Matters:
- Larger shrimp = more noticeable tract
- Tiny shrimp = barely visible tract
-
Storage Tips:
- Keep refrigerated until ready to devein
- Devein before freezing if planning to freeze
-
Cooking Guidelines:
- Cook to 145°F internal temperature
- Look for firm, pink flesh
- Avoid overcooking (nobody likes rubber shrimp!)
Common Questions I Get Asked
“Will I get sick if I eat the vein?”
Nope! As long as you cook the shrimp properly, you’re good to go.
“Does the vein affect taste?”
Sometimes it can be a bit gritty or add a slight bitter taste, especially in larger shrimp.
“Should I remove both lines?”
The top one is up to you, but the bottom nerve line doesn’t need removal.
When to Definitely Consider Deveining
You might wanna devein when:
- Serving to guests (looks better)
- Working with jumbo shrimp
- Making a clear soup or dish where the line would be visible
- If you’re particularly texture-sensitive
The Bottom Line
Look, here’s the deal – whether you devein or not is totally your choice. It’s more about personal preference than food safety. I personally devein larger shrimp but don’t bother with the small ones.
Remember, shrimp is one of the most popular seafood choices worldwide, and people enjoy it both deveined and with the tract intact. Just make sure to cook it properly, and you’re golden!
Quick Shopping Tip
When buying shrimp, look for:
- Fresh, clean smell
- Firm texture
- Clear or light gray shells
- No black spots or edges
Now you’re ready to handle shrimp like a pro! Whether you choose to devein or not, you can cook with confidence knowing exactly what those dark lines are all about. Happy cooking, everyone!

Can eating shrimp poop make you sick?
Now that we’ve established the dark line is the shrimp’s intestines—okay, yes, its poop—should you worry about eating it? While it may seem a little icky (or a lot), the general consensus is that it doesn’t pose a health risk…provided that you prepare it the right way.
“Eating the shrimp’s digestive tract doesn’t make you sick—as long as you cook it thoroughly,” says Dr. Love. That means steaming, baking, frying, or otherwise preparing it until it reaches 145°F. At this internal temperature, the shrimp will take on a firm texture.
To be clear, that’s not to say you can’t get sick from eating shrimp in general. You certainly can, but the food poisoning risk related to shellfish typically comes from eating it raw or undercooked, says Dr. Love. For instance, just like ground beef, raw shrimp can contain bacteria like E. coli. But if you cook it thoroughly, the heat will kill off the bacteria (as well as other potentially harmful pathogens that may be lurking) before it can wreak havoc with your digestive tract. So you may want to skip raw dishes like sashimi and spring for a cooked one like a curry, stir-fry, garlicky pasta, or zesty taco instead.
In fact, add shrimp—cooked right—to your diet and you’ll reap a bunch of nutritional rewards. Like other types of seafood, shrimp is a solid protein source. Just three ounces of shrimp (around 11 to 12 medium-size ones) contains around 20 grams of protein—close to the same amount you’d find in three large eggs (19 grams) or a cup of Greek yogurt (22 grams). What’s more, that portion also packs a solid punch of some other nutrients, including iron, zinc, and selenium. It even delivers around 20% of the daily value (DV) for phosphorus and 15% of the DV for vitamin B12, according to Tufts University. And while shrimp don’t contain quite as many omega-3 fatty acids as fatty fish like salmon or tuna, they still boast some of these heart-healthy compounds. (In case you were wondering, while seafood has a reputation for high mercury content, shrimp don’t pose a threat in that regard. Unlike, say, shark, swordfish, and bigeye tuna, shrimp contains low levels of the toxic chemical.)
What’s that black line in shrimp?
The dark line running through the backs of shrimp goes by many names—the dorsal tract, back vein, or sand vein, Tori Stivers, MS, a seafood specialist at the University of Georgia Marine Extension and Georgia Sea Grant, tells SELF. The marking is made up of the shellfish’s stomach, midgut, and intestine. Those structures support its digestive process, so yes, that black stuff is waste, she says.
As for what you’re actually seeing there? Shrimp are called bottom feeders for a reason: They munch on foods found in the muddy depths of the ocean, like plankton, worms, microscopic animals, and organic debris such as sand. So that black line is likely a combination of all those things in various stages of digestion, Dave Love, PhD, a senior scientist at the Johns Hopkins Center for a Livable Future, tells SELF.
