Recently, Mr. Zhu from Guangdong went to the hospital for examination because of the pain in his abdomen. Doctors found hundreds of small bugs nearly two centimeters long hidden in his liver. Doctors suspect liver flukes and immediately arrange for the patient to be tested, and the results show liver fluke antibodies.
Mr. Zhu admitted that he usually has the habit of eating sashimi, and the reason why hepatic flukes are infected may be related to this habit.
Sashimi is nutritious and delicious, and is loved by many people. However, due to the fact that raw fish may contain more parasites, especially freshwater fish, there has been a heated discussion about whether to eat raw fish.
Many people believe that as long as the sashimi is disinfected, there is no need to worry about parasites when eating. So, is that really the case? Let's take a look at it today!
Do you have good disinfection measures, can you eat sashimi with confidence?
Common disinfection measures include mustard, vinegar, high alcohol, etc. But these disinfection measures are difficult to kill parasites in sashimi. Taking hepatic flukes as an example, liver flukes often parasitize in freshwater fish, and the larvae have a protective sac wall and tenacious vitality.
Although the examination and treatment of liver fluke disease is relatively simple, liver flukes will not run all over the body and only stay in the biliary tract, but if it is not treated in time, it will slowly cause cirrhosis. Dipping white wine or mustard alone does not kill the eggs, or even destroy their sacs.
Do freshwater fish have more parasites than marine fish?
In fact, the parasites in marine fish are not less than those in freshwater fish, but because the living environment of freshwater fish is closer to the human body, it is easier for parasites in freshwater fish to survive in the human body.
On the one hand, freshwater fish live in freshwater at 15-27 ° C, a temperature closer to that of the human body, and when the parasite is transferred to the human body, it is easier to grow alive. On the other hand, the osmotic pressure of freshwater fish bodily fluids is closer to that of human bodily fluids living on land, so parasites in freshwater fish are more likely to survive in the human body.
But that doesn't mean marine fish are safe. After the study and detection of 22 species of 188 fish, including pomfret, sardines, eels, yellow croakers, etc., in addition to yellow croakers, the other 21 species were detected with isoscephalonia, and the detection rate of fish species was 95.5%. Heterocephalus can damage the digestive tract and cause allergies in the body.
Are farmed fish safer than wild fish?
Both wild and domestic fish can contain parasites. Studies have shown that both domestic and wild yellow eels may have jaw-mouth nematodes. When a person eats a fish that carries the larvae of the jawline, it will crash into the human body like a headless fly, seriously damaging the health of the body.
Not only is it easy to "annoy the worms" when eating raw fish, shrimp, shellfish, pork, etc. may contain parasites, and the types of meat are different, and the parasites are not the same.
Almost all mammals and birds can transmit Toxoplasma gondii, and the main source of human infection comes from the meat of these animals, such as shabu-shabu lamb, which is not warm enough or too short for a short time, and parasites may remain.
How can parasites be prevented?
Parasites are not the same as bacterial infections. The symptoms of bacterial infection are acute, with acute symptoms such as vomiting and diarrhea, and the reaction cycle is short.
But when the parasite eats it, it often has no symptoms at first. Parasites in the human body to go through the stage of egg laying, hatching, growth and other stages, the whole process is relatively long, for example, the survival of adult hepatic flukes in the human body can reach 20-30 years.
Because many parasitic infections begin with no symptoms or are mild and difficult to detect, the situation is generally severe when symptoms appear. Therefore, the best way to prevent parasites is to avoid "disease from the mouth".
Therefore, when eating meat or some aquatic plants, try to do the following:
1, cooked, cook thoroughly, use high temperature to kill parasites.
2, do not drink raw water, dirty water.
3. Develop the habit of cutting board classification, use different cutting boards to process different foods, especially raw and cooked, to prevent cross-infection.
4. Diners who have the habit of eating raw meat or raw aquatic plants should do a good job of cycle checks, and fight insects 1-2 times a year.
