Can rainbow trout be eaten raw?

Harmful. Few people in China eat raw rainbow trout, mainly because they are afraid of bacterial infection. Eating raw rainbow trout may infect liver flukes, lung flukes and other parasites, which are harmful to health.

There has been controversy over whether rainbow trout can be eaten raw. The China Aquatic Products Circulation and Processing Association, together with the member units of the salmon branch, issued a "group standard" for "raw salmon", stating that rainbow trout belongs to salmon. The "group standard" seemed to be able to settle the dispute, but unexpectedly, it led to even greater controversy.

Chen Shunsheng, a professor at Shanghai Ocean University, said that rainbow trout is a freshwater fish, similar in shape to Pacific salmon. The Chinese conventional name for salmon is mainly Atlantic salmon. After the "group standard" expanded the definition of salmon, "the name salmon was replaced."

Both marine and freshwater fish may have parasites, and you should also prevent parasites when eating salmon raw, but marine fish have fewer types of parasites, and the osmotic pressure of seawater is high, so they often do not grow into adults in the human body due to the unsuitable environment. Raw rainbow trout may be infected with parasites such as liver flukes and lung flukes, which are harmful to health.

The group standard "Raw Salmon" has strict regulations on parasites with reference to national standards, and explicitly requires that the origin and species of the raw fish be marked on the product label. In other words, although rainbow trout is also salmon, consumers can distinguish whether it is marine Atlantic salmon or freshwater farmed rainbow trout from the label.
