Do oysters have parasites when eaten raw? Where should I not eat oysters?

No matter what kind of food is cooked at high temperatures, there will be more or less parasites. Oysters, in particular, such as seafood, live in an environment with a lot of bacteria. There are also many experiments at home and abroad that show that raw oysters contain many bacteria and viruses.

Eating oysters raw, these bacteria and viruses can enter our body through the esophagus, erode the stomach and intestines, and continue to multiply and grow, causing great harm to our health. Parasites are actually bacteria and viruses, so it's best not to eat raw oysters. In addition, parasites also need nutrients to grow; The nutrients in raw oysters are eaten by parasites.

In addition to the good taste, it is best to eat raw oysters after cooking at high temperatures.

Many people may think that when seafood is soaked in seawater, salt can directly kill these parasites. The results showed that soaking in salt water did not kill the parasites. Many meat and seafood are parasites.

Oysters must be cooked before eating. Parasites can only be killed by high temperatures. People who usually like to eat raw oysters should avoid eating oysters directly for their own health.

What parts of the oysters should not be eaten.

1. Raw oyster shells are not edible, and it is best not to eat raw oyster offal, because raw oyster offal contains some pollutants and high heavy metal content.

2. When eating oysters, be sure to look at the color. If you see a little blackened meat, most of the meat is offal, so don't eat it. Generally speaking, when we eat oysters in a restaurant, many chefs do not remove the internal organs of the oysters when cooking the oysters because this will affect the imaging of the oysters, so when we eat oysters in a restaurant, it is best to use a knife to slowly remove the internal organs.

3. Raw oyster viscera contain a large number of metabolites and sediments, when eating raw oysters, it is best to soak them in salt water for about an hour, so that the sediment can be better metabolized.

4. When eating oysters, be sure to eat fresh ones, not spoiled ones. Fresh oysters are highly nutritious, while stale oysters can contain some harmful elements, which can affect people's health.

Yes, oyster eyes should not be eaten because they are highly toxic and can cause food poisoning.

When eating oysters, they must be steamed or roasted before they can be eaten, because oysters will have parasites if they are eaten raw, and the head of the oyster is not eaten by ordinary people.

Contains certain parasites.

Oysters generally live on shallow sea objects or reefs near the sea, feed and breathe by opening and closing shells, and usually feed on small plankton, diatoms and other organic matter, and their bodies contain certain parasites.

However, as long as the oysters are raised in a regular manner, they generally do not have a great impact on the human body, and the oysters are cooked before they are eaten, and the parasites can be killed during the cooking process, so there is no need to worry too much.

Buying oysters

1. See if there is an opening.

If you buy a whole shelled oyster in the market, it will generally stick to the mud and be dirty, so first of all, you should first see if the seams of the oyster shell are tight, if there is an opening, it is not recommended to buy. If it is an oyster purchased online, it will generally be handled relatively cleanly, and there is a slight opening when received, it may be that the oyster is dehydrated and thirsty, you can put it in light salt water to soak it, if the oyster quickly retracts and closes its mouth, it indicates that the oyster is breathing and not fresh enough.

Second, look at the appearance and shape.

The second is to choose the outer ** to go up to the thicker, take it and feel it, the same form of oysters choose heavier, the oyster shell protruding part is larger and heavier, and the oyster meat is fuller and fatter. As for the shape, some people say that they should choose a round one, but in fact, it is not necessarily, because it is necessary to divide the oysters of that sea area, and the oysters of Rushan are almost all long and of good quality, and some people say that the oysters of Zhanjiang are sweeter.

3. Try not to buy oysters soaked in water.

In front of the oyster stalls in the market, there is a row of boxes containing some oyster meat, which is sold separately by size. This soaked oyster meat may be soaked for a longer period of time and is not so fresh, and if soaked in fresh water, the raw oyster meat will look fat, but when cooked, it will shrink badly, and it will not taste good.

1 may have.

Oysters are a kind of marine organisms, which are not easy to breed orange digging bacteria and parasites, but due to the relatively large pollution of the sea in recent years, oysters may have certain parasites, and if they are eaten raw, then the parasites cannot be killed, so they will enter the human body.

Therefore, it is recommended that it is best to cook oysters before eating, if you want to eat them raw, then it is recommended to choose deep-sea non-polluting oysters, which will be relatively safer.

2. Basically, you can eat it.

Oysters are "vegetarians", mainly feeding on phytoplankton and natural seaweed in the sea, and the black, black, green and green lump of material in the stomach is actually the digestive organs of oysters and food residues that have not been completely digested, which does not contain toxic substances, and is relatively nutritious.

Therefore, the meat in the oyster can basically be eaten, but it may have a certain fishy smell when eaten, and if you can't accept it, then you can also remove this lump of material before eating.

3 all have a certain aphrodisiac effect.

From the point of view of traditional Chinese medicine, oysters are salty, slightly cold, and return to the liver, gallbladder and kidney meridians, which have the effect of calming the nerves, latent yang and replenishing yin, and dispersing knots in the human body.

However, for ordinary raw oysters, they may contain some bacteria and parasites in their bodies, so from the perspective of the human body, it is recommended that they are best cooked before eating.

1-2 for 4 large and 3-4 for small.

Although oysters are rich in nutrients, they also contain a high level of protein, and if you eat too much, it will also cause a greater burden on the body, and you are prone to abdominal pain, bloating, constipation, diarrhea and other symptoms of indigestion.

Therefore, it is recommended to eat it in moderation, if it is a large oyster, then it is recommended to eat 1-2 at a time, if it is a small oyster, then it is recommended to eat 3-4 at a time.

There are no parasites, it is better not to eat them raw, and Vibrio enteritidis and Salmonella have been detected in Vietnamese oyster products.

Vibrio parahaemolyticus (i.e., Vibrio enteritidis) is a foodborne pathogen that is mostly distributed in estuarine, coastal seawater and sediments. Vibrio parahaemolyticus is found in many aquatic products, such as cod, sardines, clams, octopus, shrimp, crabs, lobsters, crayfish, scallops and oysters.

Salmonella is considered to be one of the most important foodborne pathogens worldwide, and many food products such as meat (especially poultry), eggs and egg products, unpasteurized milk and dairy products, etc., have been linked to Salmonellosis. In recent years, salmonella has been detected in fish and shellfish such as rainbow trout, tilapia and Atlantic salmon, and even on the surface of water bodies.

Oysters are a kind of seafood that is delicious and loved by many people. However, some people often worry about whether eating oysters will cause parasites. So, do oysters have parasites? Let's take a look at the situation.

Parasite species.

Parasites refer to organisms that rely on other organisms as hosts and illegally use the substances and other conditions in the host to grow and reproduce. There are two types of parasites associated with oysters, one is a zoonotic fluke and the other is a tapeworm in marine animals.

Impact on people.

People are worried that eating oysters with parasites can lead to some adverse reactions such as diarrhea, abdominal pain, nausea, etc. However, the number of parasites is very small and generally does not have a major impact on human health.

How to prevent it. To avoid eating oysters with parasites, we can take the following precautions:

Choose regular merchants to buy oysters, and try to avoid buying them at street stalls, etc.;

Carefully check the quality of the oysters before eating them, and do not eat them if they look bad or have an off-flavor;

If you are concerned about parasites, you can roast, steam or cook the oysters to avoid the presence of parasites.

Conclusion. On the whole, oysters have the possibility of parasites, but the number is very small, and the source of oysters generally does not have a major impact on human health. As long as we buy oysters from regular merchants and carefully check the quality of the oysters before eating, or choose to guess the oysters roasted, steamed or cooked, we can avoid the potential risks posed by parasites to our health.
