Does salmon have parasites

Salmon is a fish that is very suitable for eating raw. Due to its good taste when eaten raw, many people have fallen in love with sashimi. Especially in Japan, the way of eating salmon is more particular. Although salmon is delicious, some people question whether salmon has parasites. It does not rule out that any fish carries parasites, but it is also related to the environment in which the salmon grows. Let's learn more about whether salmon has parasites?

1. Classification of salmon and whether it contains parasites

According to the sea areas where they live, salmon can be divided into two categories: Pacific salmon and Atlantic salmon. Pacific salmon mainly live in Alaska in the United States and Hokkaido in Japan. Most of them are wild fish that swim between rivers and seas. Therefore, it is generally believed that Pacific salmon are freshwater river fish and contain more bacteria and insects. The North Atlantic salmon from Norway and Chile do not go through the process of "going back to the river" and are generally farmed in the deep sea, so they are more suitable for sashimi. However, deep-sea salmon are not absolutely parasite-free, and eating raw marine fish cannot eliminate the risk of parasite infection. Compared with parasites, fish are more likely to be contaminated by microorganisms during transportation and processing, and need more attention. There is a kind of fake salmon on the market with the scientific name "rainbow trout". This fish is a freshwater fish and is not suitable for consumption as sashimi. If you encounter salmon that is "freshly caught and cut", please be careful. Not only do restaurants use rainbow trout to impersonate salmon, but salmon meat or products sold in supermarkets are sometimes also impersonated by rainbow trout meat.
