What could be more delicious than eating a fish raw?
But the disease comes from the mouth, and some things really can't be eaten indiscriminately...
1. Eating raw fish became a habit and was diagnosed with liver fluke disease
Recently, a Mr. Zhu from Zhongshan, Guangdong Province, had a lot of pain in his abdomen, and he was surprised by the results after checking at the hospital. Mr. Zhu thought it was just a minor illness, but he did not expect that the doctor found that there were hundreds of small bugs nearly two centimeters long hidden in his liver during the examination...

Oh my goodness! So many insects, how did it enter Mr. Zhu's body, is it harmful to the human body?
After judging, the doctor suspected that the worm in the patient's liver was most likely a liver fluke. And immediately arranged for the patient to conduct an in-depth examination, the results showed that the judgment was not wrong...
In order to help Mr. Zhu excrete the liver flukes in his body, the hospital immediately arranged surgery for him. After the operation, a biliary drainage tube was placed in place for the patient, and the insecticide was taken orally. Eventually, there are hundreds of bugs drained through the catheter.
The doctor also expressed surprise, how did Mr. Zhu get this disease? Under careful questioning, I learned that Mr. Zhu had the habit of eating raw fish. The reason for this infection with this liver fluke disease is probably related to this habit.
In fact, in many parts of China, "fish raw" has gradually become a food culture.
By descaling, deboning and slicing selected freshwater fish, and dipping sauces such as soy sauce, sesame oil and mustard, diners can enjoy the original taste of raw fish.
However, this diet method hides many hidden dangers. Among them, hepatic fluke disease is the most important disease to pay attention to.
So what is hepatic fluke disease?
Liver fluke eggs like to "hide" in freshwater fish and shrimp, etc., as people eat raw, unripe fish and shrimp and other ways to quietly lurk into the human body, making people sick.
When people are infected with hepatic fluke disease in the early stage, the symptoms are not obvious, mainly diarrhea, bloating, epigastric pain, physical discomfort, poor appetite, fatigue and so on.
If left untreated and treated, severely infected people with hepatic fluke disease can cause complications such as cholangitis, gallstones, and cirrhosis.
One might say that eating sashimi is not dipped in vinegar and mustard, and these spices can help kill parasites.
But in fact, this perception is wrong.
Experts did a specific study and they found that:
Even if soaked in high concentrations of mustard, garlic juice, vinegar and soy sauce, liver flukes can survive in it for several hours, put in the mustard sauce and cover the lid for 20 minutes, only about 3% of the larvae die, and the larvae soaked in high liquor can survive for more than 40 minutes...
Therefore, it is not realistic to rely on mustard and vinegar to kill parasites. The best way to kill liver flukes is at high temperatures. Only by boiling the fish thoroughly can the parasite be killed.
In addition to liver flukes, this newspaper also shared cases of fresh diseases in an article on Saturday. This parasite has been found in fresh fish in Japan and Australia...
2. How to prevent parasites?
So these parasites are so terrible, how do we prevent them?
First of all, eating sashimi to make sure that 100% is parasite-free is not possible. To pursue 100% safety, it is necessary to avoid mouth.
However, if fresh fish are frozen rapidly (-35°C for 15 hours) and processed by an experienced sushi chef, the likelihood of contracting the parasite and developing a serious disease is low.
In particular, if you or someone close to you is in the following situations: cancer patients, AIDS patients, organ transplant patients, various immunocompromised patients, seafood allergy people, children under 3 years of age, and the elderly (generally defined as 65 years old and older), please avoid using any raw fish!
What should I do if I can't give up the delicious food and worry about my health?
1. Eat only rapidly frozen marine fish (including salmon, tuna, etc.).
2. Find a trustworthy sushi restaurant and sushi chef to eat the raw fish that has been screened and processed.
3. Eat only tuna (tuna is a fighter in the deep sea, swimming fast, so the parasitic infection rate is extremely low, is the US Food and Drug Administration licensed to enter the raw fish meat without rapid freezing).
4. It is best not to eat freshwater fish raw.
5. Raw and cooked foods should be stored and cut separately to avoid cross-infection between foods.
In Australia, where water is abundant, there are also frequent cases of nematodes infected with sashimi by diners. Chinese who like to eat sashimi should pay special attention!
At last
Most importantly, if you feel unwell after eating raw fish, be sure to seek medical attention in time and tell the doctor that you have recently eaten raw fish!
