Shrimp is undoubtedly one of the most delicious seafood presents globally; it is almost impossible not to find it in the restaurant. It practically goes well with every dish that we can imagine, and it is used in sushi too.
Leaving out the fact that it can be used almost everywhere, it is important to consider the condition of the shrimp before purchasing it or eating it, because eating a shrimp that has gone bad can cause food poisoning.
So, how to tell if shrimp is bad? To understand if a shrimp has gone bad, you have to perform 3 actions: 1. check the shrimp’s color by ensuring that the color range is between brown and pink (depending on the typology), 2. Check the smell; if you feel that it is too fishy smelly, it means it is bad. 3. Checking the consistency of the shrimp.

3 Things to Check To Recognize when a shrimp is gone bad
Depending on the situation, there could be different causes, and you might face different scenarios to evaluate the quality of your shrimp. The most common scenario when we will arise in our mind the question about the quality of the shrimp is when:
- We are purchasing the shrimp fresh
- We are buying the shrimp frozen
- We are eating the shrimp
Depending on the situations where you will find yourself, there could be different methods of valuations regarding the conditions of the shrimp. But do not worry because now we will see every aspect in detail.
How to understand if the shrimp is bad when purchasing it fresh

But in today’s life, there could be some possibility of a scam, and recognizing a fresh shrimp from a bad one is an important skill that will help you evaluate its condition when you are purchasing it fresh.
The most important thing to check is the color of the shrimp. Since there are different types of shrimp, it is important to recognize which one of them you have in front; because of the different varieties, you might purchase pink, brown, very red shrimp.
