How to distinguish clean shrimp and shrimp injected with impurities
The danger of shrimp injected with chemicals and treated with urea
The act of injecting shrimp with impurities and banned antibiotics to increase their weight or keep them fresh for a long time, etc. is not only a fraudulent act, it also affects the health of consumers. According to Dr. Doan Thi Tuong Vi (Deputy Director - Institute of Clinical Nutrition), shrimp injected with chemicals (especially liquid impurities) is a suitable environment for many types of bacteria to grow. If consumers eat this type of shrimp, they are very susceptible to food poisoning leading to digestive disorders, diarrhea, typhoid, dysentery, etc.
In addition, to keep the appearance of fresh shrimp longer, many sellers also use urea to marinate. Using urea-soaked shrimp has the risk of acute poisoning, chronic poisoning, insomnia, physical weakness, memory loss; affects the liver, kidneys, etc.
How to distinguish clean shrimp from shrimp "injected with chemicals"
One of the ways to check fresh shrimp that many wise housewives apply is for frozen or steamed shrimp, you pick up the shrimp, hold the head and tail of the shrimp to pull the shrimp straight. When you see the joints between the shrimp segments are tight, it is fresh shrimp, but if these joints are wide, it means the shrimp has been frozen for too long.
Never choose shrimp that has turned pink because it is spoiled. With mantis shrimp, in addition to being alive, you should choose shrimp with a pink-white shell and blue-black eyes. As for iron shrimp, do not choose shrimp with a dark pink color because the shrimp is old and no longer fresh.
Check the width between the shrimp joints
When buying shrimp, to know if the shrimp is fresh or not, it is best to look at the tail first. Check the tail of the shrimp to determine their freshness.
One of the great tips to check the freshness of shrimp. Especially for large shrimp, you hold the shrimp up to the light and stretch the shrimp and look at the width between the joints on the shell and the shrimp meat. When you check this wide joint, it shows that the shrimp is not fresh because it is left for too long or left in the freezer for a long time, the narrower the shrimp joint, the fresher the shrimp meat.
