Additional information:

Wild salmon has many parasites, the most common of which is Anisakis, which can easily cause abdominal pain and diarrhea. However, marine parasites cannot survive in the human body for a long time.

In comparison, farmed salmon may have fewer parasites. It is worth noting that freshwater farmed rainbow trout is sometimes used for sashimi, but its risk is much greater than that of salmon.

This is because parasites in freshwater fish can survive in the human body, the most common of which is liver fluke. Therefore, freshwater farmed rainbow trout cannot be eaten raw. Anisakis can be killed by freezing. The Shanghai Food and Drug Administration recommends freezing at minus 20 degrees Celsius for more than 24 hours or freezing at minus 35 degrees Celsius for 15 hours, in accordance with foreign standards.
