Can Eating Crab and Tomatoes Together Cause Poisoning? Eating Dead Crabs and Steaming Times

Every Mid-Autumn Festival season, large quantities of crabs start to hit the market in China, and at this time many people also like to buy a few to take home and eat steamed, boiled, and so on. However, because there are particular ways to eat crabs and many foods that clash with them, you must be careful when eating them, so can eating crab and tomatoes cause poisoning? Can they still be eaten after they die? How long should they be steamed to taste best?

1. Can eating crab and tomatoes cause poisoning?

Eating crab and tomatoes together will not cause poisoning. Although crab contains arsenic, its content is far below the national standard, and after combining with the vitamin C in tomatoes it will not produce a substance similar to arsenic trioxide, so eating them together will not cause poisoning. However, people with a cold constitution or indigestion should eat as little as possible, because crab is cold in nature and can cause diarrhea, indigestion, and similar symptoms in people with a cold constitution or an upset stomach.

2. Can crabs still be eaten after they die?

Crabs cannot be eaten after they die; even those that have just died cannot be eaten. This is because crabs have a very broad diet and mostly feed on animal carcasses and rotting food, harboring large amounts of bacteria or harmful substances inside. After death they produce the toxic substance histamine, and it is very easy for bacteria or harmful substances to spread to other parts, causing abdominal pain, diarrhea, and similar symptoms after people eat them, so it is best not to eat them.

3. How long should crabs be steamed to taste best?

Crabs generally only need to be steamed for about thirty minutes, but if they are larger individuals the time can be appropriately extended to thoroughly kill the bacteria and harmful substances inside. However, when steaming or boiling, the length of time still needs to be determined by the size and number of the crabs and the heat level, so the specific time still has to be decided according to the specific situation. Under normal circumstances, when the shell is cooked until it is glossy and red, it means it is already thoroughly cooked.

4. Which parts of a crab cannot be eaten?

1. Crab stomach: The crab stomach is in the crab roe inside the back shell of the crab, and its shape is a triangular sac. When opening the crab shell, use a spoon to take out the crab roe, then gently suck the crab roe with your mouth until a hard lump appears, which is the triangular sac.

2. Crab gills: The crab gills are on both sides of the crab's head and thorax, and generally can be seen as soon as the crab shell is opened; like fish gills, they are distributed on both sides in a whisker-like form. This place has the most bacteria, and eating it can easily cause diarrhea, abdominal pain, and similar symptoms.

3. Crab heart: The crab heart is in the center of the crab's head and thorax area, wrapped in a hexagonal capsule, and generally can be seen as soon as the crab shell is opened.

4. Crab intestine: The crab intestine is at the end of the crab's head and thorax area, and generally can be seen after opening the crab shell; it appears as a black line, part of which is wrapped in the crab roe, so you must carefully remove it when eating. This place also has relatively many bacteria and impurities, so it is best not to eat it.

5. Crab mouth: The crab mouth is a little below and between the crab's two eyes, with several movable plates; this part cannot be eaten.

5. Must crabs be sold tied with rope?

Crabs can be sold without being tied with rope, but they easily hurt people and easily cause the crab roe to leak out, the crabs to escape, the crabs to fight each other, and similar situations, so many vendors habitually tie them up to sell them. However, if you go to a live crab market to buy crabs, the vendor can let the consumer choose the crabs first and then tie them up, and this is also acceptable.
