Salmon can be eaten raw or cooked. Raw food tastes delicate, and the fish is bright in color, orange or orange, which looks very appetizing. Most people want to eat fish? Fresh? Slice the salmon and dip it in the seasoning, not to mention how delicious it is. But while delicious, there is also a hidden risk, that is, parasites. I remember there was a news before that a man in Shunde, Guangdong likes to eat salmon raw, and he often feels unwell after eating it. He went to the hospital for an X-ray and found that there were many parasites in his body, which was the chief culprit of his long-term physical discomfort.
Are there parasites in salmon? Of course, animals living in the wild will have parasites more or less, and it is safest to eat them when cooked. Although some people know that cooking and eating are safe, they are willing to take a little risk in the face of delicious raw salmon. Many people think salmon sashimi is delicious, which is better than cooked food. Salmon sashimi is a kind of cuisine, which is made of raw salmon fillets and is called sashimi.
Parasitic infection of marine salmon is mainly anisakis, which can not survive well in human body. Unless you eat a lot of raw meat containing more anisakis nematodes, it is difficult to really infect the human body. But it doesn't mean that raw food is relatively safe, but there are still some risks. In Japan, many people say that Japanese food is safe, but it is not. In recent years, the number of people who go to the hospital because of infection has increased year by year, mainly because Japanese people like to eat sashimi. Even the Japanese Ministry of Health has issued a warning because of this incident, reminding consumers to pay attention to the infection risk of heterologous bacteria.
It is not difficult to kill anisakis, and it dies quickly at high temperature. Of course, freezing can also kill anisakis. For this reason, the European Union stipulates that seafood must be frozen at minus 20 degrees Celsius for 24 hours before it can enter the market. America is stricter. It is recommended to freeze at MINUS 20 degrees Celsius for one week. If it is MINUS 35 degrees Celsius, you can enter the venue after freezing 15 hours. China's standards are similar to those of the European Union. It takes more than 24 hours to enter the market at minus 20 degrees Celsius. Therefore, it is safe for us to buy salmon products that meet this standard.
However, in the salmon market, some freshwater fish are also used to make salmon. Parasites infected by freshwater fish can survive well in human body, which greatly increases the risk of infection, such as clonorchis sinensis infection. This parasitic infection disease is more dangerous, which can parasitize bile duct and gallbladder, cause pathological changes and even induce tumors. It is classified as a 1 carcinogen by the World Health Organization. It is a carcinogenic parasite and very dangerous. Freezing is not easy to kill clonorchiasis, but it still needs high temperature heating.
So from this perspective, eating cooked food at high temperature is the safest way.
Back to the topic, why should salmon be eaten raw? Cann't you boil it in water?
Eat salmon raw because it tastes delicious. It is safe to buy raw salmon from regular channels, but there is no guarantee. Many people are willing to take this risk and eat salmon raw, but they don't know that you may be at risk of being infected by parasites. Therefore, it is safe to eat cooked food at high temperature, and all meat products should do so.
