It's okay to eat it once or twice occasionally, even parasites won't kill you, because the immune system in the human body can kill a small amount of parasites, but if you eat it for a long time, it will be serious.

Rainbow trout is a freshwater fish, and it is parasitic, and it is often used to fake salmon. If you don't feel well, go to the hospital and ask the hospital to open an insect repellent for you, but remind you that insect repellent is also toxic ~

What's more, salmon itself carries many parasites. Frozen preservation and mustard can kill insects in theory, but it can't be completely killed. Generally speaking, there are two kinds of salmon on the market, one is Atlantic salmon, also called Norwegian salmon, which can be eaten raw because there are fewer parasites. Another kind of salmon is called Pacific salmon. This kind of salmon has many parasites and can't be eaten raw (but it can be cooked), so you need to pay attention.
