Reasons:1Dead crabs or dying crabs may have been purchased.

When a crab is dying or dead, the bacteria break down the proteins in the crab and give off a foul smell. When cleaning crabs, it is essential to carefully inspect for partial deaths, such as crab legs. If the crab leg is necrotic, it can also be cooked.

It may be because the crab is not fresh and has rotten parts inside, which causes the smell. It is advisable to use sturdy crabs and consume them as soon as possible after cooking.

2.May be undercooked. Sometimes the smell and fishy smell are similar.

If the crabs are not cooked, they will have a fishy smell. If you boil the crab, it will take a longer time to cook it. If the crabs are not cooked thoroughly, they will also have a large fishy smell.

Extended Information: Tips for Eating Crabs:

First, choose fresh, live crabs and don't eat raw crabs or drunk crabs. Crabs are omnivores, and even eat the carcasses or humus of other animals, and their body surface, gills and gastrointestinal tract are covered with various bacteria, sludge and possibly even parasites. Therefore, before eating crabs, you must scrub them clean, do not eat gills, intestines and other internal organs, and they must be steamed and cooked thoroughly before eating.

Second, don't eat too much. The protein contained in crabs and the cholesterol in crab roe are relatively high, and excessive consumption at one time is not conducive to human digestion and absorption, so the average person should not eat more than 1 catty of crabs each time, and should not exceed 3 times in a week.

Crabs that smell bad and are not fresh cannot be eaten, especially dead crabs. Crabs contain more histidine in their bodies, and the longer the crab dies, the more histidine accumulates in the body, and even if the dead crab is cooked, this toxin is not easily destroyed.

In addition, there are lung fluke larval cysts and Vibrio parahaemolyticus in the body surface, gills and gastrointestinal tract of crabs, which can cause lung damage after entering the human body without high temperature disinfection. If Vibrio parahaemolyticus invades the human body in large quantities, infectious poisoning will occur, and symptoms such as intestinal inflammation and bleeding will occur.
