Wild salmon may have more parasites than salmon.

Wild salmon has many parasites, with Anisakis being the most common, which can easily cause abdominal pain and diarrhea. However, seawater 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 cultured rainbow trout is sometimes used for sashimi, but its risk is much greater than that of salmon. This is because parasites found in freshwater fish can survive in humans, the most common of which are liver flukes.
