Let me tell you something straight up – if your frozen shrimp has a strong fishy smell, that’s a red flag you shouldn’t ignore. I’ve learned this the hard way after years of cooking with shrimp, and today I’m sharing everything you need to know about frozen shrimp and those suspicious fishy odors.
The Quick Answer
No, frozen shrimp should not have a strong fishy smell. Fresh, properly frozen shrimp should have just a mild, ocean-like scent. If you’re getting hit with an overpowering fishy or ammonia-like odor, that’s your cue to toss it out.
Why Does Frozen Shrimp Sometimes Smell Fishy?
Here’s what usually causes those unwanted fishy odors:
- Bacterial Growth: When shrimp isn’t handled properly during processing or storage, bacteria multiply quickly
- Poor Freezing Methods: Slow freezing or refreezing thawed shrimp creates perfect conditions for bacteria
- Oxidation: When shrimp gets exposed to air, especially at warmer temps, it starts breaking down
- Contamination: Sometimes things like bilge water during fishing can taint the shrimp
- Overcooking: This can intensify any existing off-odors

Common Questions I Get About Fishy Shrimp
Q: Can I cook away the fishy smell?
A: Nope! Cooking won’t make spoiled shrimp safe to eat.
Q: Will soaking in milk help?
A: That’s an old wives’ tale – if it’s truly spoiled, no amount of milk will help.
Q: What about black spots on the shell?
A: Those are usually just melanosis and are safe if only on the shell.
Bottom Line
Trust your nose on this one – if your frozen shrimp smells fishy, it’s probably gone bad. Better to waste a few bucks tossing it than risk getting sick. When in doubt, throw it out!
Remember, good frozen shrimp should smell like a fresh ocean breeze, not like the dumpster behind a seafood restaurant. Stick to proper storage methods, and you’ll be enjoying delicious, non-stinky shrimp in your favorite recipes.

Shrimp Smell Removal Additional Tips & Tricks
If you want to take your shrimp odor removal game to the next level, or the primary hacks didn’t quite do the trick, don’t worry! I’ve got a few more tips and tricks up our sleeve to ensure your shrimp are as fresh and fragrant as possible.
- Milk Soak: If you’re still noticing a slight fishy odor after trying the previous hacks, soaking your shrimp in milk for 15-20 minutes can help neutralize it further. The milk proteins bind to the TMA (the compound responsible for the smell), effectively removing it.
- Herb & Spice Infusion: Not only do herbs and spices add flavor to your shrimp, but they can also help mask any lingering odor. Toss a few sprigs of thyme, rosemary, or bay leaves into the cooking water, or try adding a pinch of your favorite spice blend.
- Proper Storage: Prevention is key! To avoid fishy smells in the first place, ensure proper storage of your shrimp. Keep them in the coldest part of your refrigerator (usually the back) and use them within a day or two. If you’re not planning on cooking them right away, freezing is the best option for maintaining freshness.
- Other Options: While less common, you can also experiment with soaking shrimp in a weak coffee solution or using lemon peels to help neutralize odors. These methods might not be as effective as the primary hacks, but they could be worth trying if you have the ingredients on hand.
Why Does Shrimp Smell Fishy?
Fresh shrimp should have a mild, slightly salty aroma of the sea. The overpowering “fishy” smell develops when enzymes and bacteria break down the proteins in the shrimp, producing trimethylamine (TMA), the compound responsible for the pungent odor.
It’s important to distinguish between fresh shrimp and spoiled shrimp – if the smell is ammonia-like, throw it out! If you question it all, it’s not worth including it in your dish.
The following hacks work best on fresh shrimp to neutralize any early odor development. And I’ll tell you the shrimp smell removal hack that I use all the time and why.
