Crabs are not only delicious and rich in vitamins, but they also have certain medicinal value. However, many people experience symptoms such as abdominal pain, diarrhea, nausea, and vomiting after eating crab. This is usually because they didn't pay attention to the details when eating crab. Pay attention to the following 8 aspects to minimize the problems that may occur after eating crab.
1. Eat live crabs, not dead ones
The rigidity and autolysis periods of a river crab after death are greatly shortened. Bacteria in the crab's body will rapidly multiply and spread to the crab meat, causing the eater to vomit, experience abdominal pain, and have diarrhea.
The shell of a fresh, live crab is dark greenish-black with a lustrous sheen, and its abdomen is full and white. A dying crab, on the other hand, has a yellowish shell, softer legs, and difficulty turning itself over.
2. Steam or boil crabs thoroughly; do not eat raw crab
Crabs feed on animal carcasses or humus, so their body surface, gills, and gastrointestinal tracts are covered with various bacteria and silt. If people don't wash the crabs clean, steam or boil them thoroughly, or eat raw crabs marinated in wine or pickled, they are consuming the bacteria or parasites inside the crab. How could they not get sick? This problem won't exist if the crab is steamed or boiled thoroughly before eating.
3. Steam and eat crabs immediately; do not store them
If you can't finish them, the leftovers must be stored in a clean, cool, and well-ventilated place. Before eating, they must be reheated and cooked thoroughly again.
4. Don't eat crab carelessly
When eating crab, after opening the top shell, pay attention to the four removals: remove the crab stomach, which is the small, triangular, bony package inside the crab's shell. First, eat the top shell part, use a small spoon to scoop out the middle crab stomach part, and gently suck the crab roe clean from the surrounding area. Note: do not suck the triangular-shaped crab stomach in the middle, as it contains dirty sand and should be discarded. After eating the top shell, move on to the crab body. First, use scissors to cut off the extra crab legs and mouthparts. Use a spoon handle to pick out the hexagonal, plate-like object in the middle of the crab's body; that is the crab heart and should be discarded. Also, remove the crab intestine, which is the black line running from the crab stomach to the crab's navel; and the crab gills, which are the two rows of soft, eyebrow-like things on the crab's abdomen.
5. Eat in moderation; do not eat too much
Crab meat is considered "cold" in nature. People with a weak spleen and stomach should be especially cautious to avoid causing abdominal pain and diarrhea.
6. Try to avoid drunken or raw crab
Although raw crab is delicious, it may not only have various viruses and bacteria attached to it, but it may also be parasitized with lung fluke cysts. Simply marinating it in yellow wine, white wine, etc., cannot achieve a thorough sterilization and disinfection effect.
7. Do not eat with tea
Do not drink tea while eating crab or for 1 hour after eating. Because tea can dilute stomach acid and cause certain components of the crab to solidify, which is not good for digestion and absorption and may also cause abdominal pain and diarrhea.
8. Do not eat with persimmons
When crabs are in season, persimmons are also ripe. These two foods should not be eaten at the same time. Tannic acid and other components in persimmons can cause the crab meat protein to coagulate. This coagulated substance will remain in the intestines for a long time, ferment and spoil, causing reactions such as vomiting, abdominal pain, and diarrhea, and it may also cause conditions like stone formation.
Note: (Four parts of the crab should not be eaten)
1. Crab gills: The crab's respiratory organs, which are very dirty. Remove them first after opening the crab shell.
2. Crab intestine: Contains the crab's excrement.
3. Crab stomach: The triangular package hidden in the crab roe. Like the intestine, it contains the crab's excrement.
4. Crab heart: Also called the crab's hexagon plate. This is in the crab roe, it's hard to find, but its hexagonal shape is very noticeable.
Take a look at this before eating crab again, it would be a shame to have symptoms like diarrhea from not knowing how to eat it properly.
