The Teochew people eat sashimi, originating from the Tang Dynasty, the popular chop is eaten raw. Why TV reports now infected with parasites are almost all other places and Chaozhou almost no (not that Chaozhou people eat raw fish will not be infected with parasites)?

First of all, the living environment of the fish, Chaozhou sashimi usually choose grass carp, the ponds used to raise fish will flow into the domestic sewage and even livestock feces. Once someone or livestock infected with liver fluke, feces centimeters of eggs and then into the pond, the pond inside the fish, shrimp, snails and so on and so infected, the formation of a dead cycle, so before a lot of people who do not eat (mainly can not afford to eat) fish sashimi is also infected with liver fluke. Nowadays, fish are all feed farmed, and there is almost no human or animal life near the ponds, plus people's quality of life has greatly improved, and all households have septic tanks, so the probability of contamination has been greatly reduced.

Secondly, how to eat: in Chaozhou, about 4 pounds of grass carp after slaughter (pinch the head and tail, peel off the skin to remove the red meat and other surface meat) can be eaten on the left about a pound, so that is the high probability of infection of the surface meat, especially the skin removed, and once again to reduce the risk.

Lastly look at the cutting board: killing fish and filleting is a different cutting board, each cut a sashimi will use a knife to scrape the cutting board (not wipe) clean

On the other hand, other places to do sashimi, to the market to buy a fish let the fishmonger on the spot slicing, and even some for the sake of plating look good, the fish in addition to scraping the scales of the basic all cut into slices of fish. Both unhygienic, but also affects the taste, eat a hairline fish raw, so what is the difference between eating and drinking blood?
