Chaozhou people's eating of sashimi originated in the Tang Dynasty, and it is well known that sashimi is eaten raw. Why is it reported on TV that almost all people infected with parasites are from other places, while there are almost no parasites in Chaozhou (not to say that chaozhou people will not be infected with parasites if he eats sashimi)?

First of all, the living environment of fish, Chaozhou fish generally choose grass carp, and the ponds that used to raise fish will flow into domestic sewage and even livestock manure. Once people or livestock are infected with Clonorchis sinensis, eggs with feces cm will flow into the pond again, and fish, shrimp and snails in the pond will be infected, forming an infinite cycle, so many people who have not eaten raw fish (mainly can't afford it) are also infected with Clonorchis sinensis. Nowadays, all the fish are fed, and few people and animals live near the pond. In addition, people's quality of life has been greatly improved, and every household has septic tanks, which greatly reduces the probability of pollution.

Secondly, how to eat it: in Chaozhou, after a grass carp weighing about 4 kg was slaughtered (cutting off the head and tail, peeling off the surface meat such as red meat), only about 1 kg was left. This is to remove the surface meat with high infection probability, especially the fish skin, and reduce the risk again.

Finally, look at the chopping block: killing fish and cutting fish are different chopping blocks. Every cut fish will be scraped (not wiped) clean with a knife after it is born.

On the other hand, raw fish is made elsewhere. You can buy a fish in the market and let the fishmonger slice it on the spot. Some people even cut the fish into fillets, except for scraping the scales. Unsanitary, but also affect the taste. What is the difference between eating raw wool and eating raw fish?
