4 types of seafood to deceive buyers, be careful not to lose money

1. Shellfish

Before, people rarely heard about weight cheating seafood, however, the way to do it is very simple. When soaked in salt water with a certain concentration, shellfish such as oysters and clams will absorb a lot of salt water, becoming plump and soft, but the weight also increases a lot, when you go home, it will shrink. and no meat.

2. Crab, crab

Crab has a delicious taste, a favorite dish of many people. Crab is not cheap, some are sold by the child, some are weighed by weight, up to millions of VND 1 kg. Therefore, when choosing crabs, you should pay special attention to the following points.

If you buy a lace-up whole, you can tell if it’s alive or dead by seeing if it spits air bubbles and if its eyes are moving.

Since many may have died, then it will contain a lot of bacteria, inedible and harmful to the stomach.

If the crab is weighed by the weight, it is best to buy the untied type, because the crab leash is very heavy, sometimes 5-7 pounds, so it will cost the buyer more money.

3. Shrimp

In many places, shrimp are sold wrapped in a thick layer of ice, traders say this is done to keep the shrimp meat fresh and tender. However, when I bought it, I found that the shrimp was friable and had an unpleasant smell.

Shrimps that are frozen directly in ice can keep for a long time, but shrimp in the market are often thawed and then re-frozen many times, easy to breed bacteria, lose water and spoil. With shrimp, it is best to buy fresh shrimp and peel it yourself, not frozen shrimp.

4. Hogfish

Traders often say that the fish will inevitably be bumped during transportation, so it is normal for the silver luster on the surface to fall off.

However, if the fish is fresh, the silver layer on the surface is very strong and difficult to fall off. This silver is not a fish scale but a special layer of fat containing a lot of unsaturated fatty acids, very good for health, so when buying fish, if you find this silver is low, it means that the fish has been prepared and spoiled. should buy.
