1. Are there crystal rods for king crabs? I bought a king crab. Then I found a transparent worm on its shell. Can I still eat it?

Anyway, it doesn't matter if it's cooked or not. I'm really unhappy, so there's nothing I can do about it.

2. Eating seafood will contain a lot of bacteria and microorganisms. Are there any good ways to prevent them?

Remember not to eat seafood when drinking beer, but you can eat seafood when drinking liquor because it can kill bacteria.

Drinking beer while eating seafood may be a habit for many people, but nutrition experts point out that seafood is a high-protein, low-fat food containing purine and glycoside acid. Beer contains vitamin B1, which is a catalyst for the decomposition and metabolism of purine and glycoside acid. When purine, glycoside acid and vitamin B1 are mixed together, a chemical reaction will occur, causing the uric acid content in the human blood to increase rapidly, destroying the original balance. If uric acid cannot be excreted from the body in time, it will precipitate in the form of sodium salt, forming stones or gout. When this kind of patient is serious, the body is covered with red bumps, itching and pain, rolling on the ground, unable to walk.

Therefore, experts recommend not drinking beer when eating seafood. You can boil the seafood first to remove purine and glycoside acid; drink a lot of boiled water to excrete uric acid from the body in time. When eating seafood, eat some vegetables and fruits rich in vitamins A, C, and E to reduce the precipitation of uric acid. However, cauliflower, spinach and mushrooms are exceptions.

How to eat seafood more safely

1. Freeze seafood before eating it raw and pour some light salt water on it. Oysters and some aquatic shellfish often contain a kind of bacteria called "Vibrio vulnificus". For people with poor intestinal immune function, eating seafood raw is potentially fatal. American researchers have found that putting oysters on ice first and then pouring some light salt water on them can effectively kill this bacteria, making it safer to eat raw.

2. Don’t drink beer with seafood. Drinking a lot of beer while eating seafood will produce too much uric acid and cause gout. Excessive uric acid will be deposited in joints and soft tissues, causing joint and tissue inflammation.

3. Arthritis patients should eat less seafood, because sea cucumbers, marine fish, kelp, and seaweed contain more uric acid, which can form uric acid crystals in the joints after being absorbed by the human body, aggravating arthritis symptoms.

4. Avoid eating seafood with certain fruits. Fish and shrimp are rich in nutrients such as protein and calcium. If they are eaten with fruits that contain more tannic acid, the nutritional value of the protein will be reduced, and the calcium in the seafood will easily combine with tannic acid to form a new substance that is difficult to digest. Fruits that contain more tannic acid include persimmons, grapes, pomegranates, hawthorns, green fruits, etc.

5. Do not eat shrimps with vitamin C. American scientists have found that eating shrimps and other aquatic crustaceans while taking large amounts of vitamin C can be fatal, because an arsenic that is generally considered harmless to the human body can be converted into toxic arsenic under the action of vitamin C.

What should you pay attention to when eating seafood

1. When eating seafood, drink some white wine and rice vinegar in moderation, but it is not advisable to drink beer when eating seafood, because drinking a lot of beer when eating seafood will produce too much uric acid and cause gout.

2. After eating seafood, do not consume cold drinks, watermelon and other foods within one hour, and do not go swimming immediately;

3. Seafood is rich in protein. People who are allergic to protein should not overeat. (Seafood poisoning is caused by this.)

4. Seafood should not be eaten with fruits rich in tannic acid, such as persimmons and grapes. If you have to eat them together, there should be at least two hours between them, because tannic acid will destroy the high-quality protein in seafood and greatly reduce the nutritional value of seafood.

5. The head of marine fish is rich in the mineral arsenic, which will be converted into toxic trivalent arsenic (As3+) under the action of a large amount of vitamin C. Its toxicity is equivalent to arsenic trioxide. Therefore, you should avoid taking vitamin C pills within two hours before and after eating marine fish.

3. Putting crabs in the refrigerator will breed bacteria

Hairy crabs are cold-resistant but not heat-resistant. Live crabs can be placed in the refrigerator, but not in the freezer. If you add some water every day, they can be kept for about ten days. However, they will not be as plump as before, so it is recommended not to keep them for too long. Live crabs will not produce bacteria, but dead crabs cannot be eaten. Once dead, they will produce a lot of bacteria.

4. What kind of bacteria is this? It grows in cosmetics.

It must be mold if it grows this big.

5. How do aquaculture farmers determine what are good bacteria?

Farmers do not need to know how to specifically judge whether bacteria are good or bad. They just need to know that bad bacteria can cause disease and lead to the death of a large number of aquatic products. Good bacteria can be used to adjust water or for treatment, such as Bacillus, EM bacteria, lactic acid bacteria, photosynthetic bacteria, Escherichia coli, etc.

6. Please identify what bacteria this is

It's negative, it won't hurt.
