Producers of fish products in the Russian Federation continue to replace salmon with cheaper trout.
According to the Federal State Budgetary Institution „National Center for the Safety of Fish Products” (NTsBRP) subordinated to Rosselkhoznadzor, this is confirmed by the results of ongoing research.
Thus, in the first half of this year, the center’s reference laboratory received 24 samples of Atlantic salmon (salmon) for DNA testing. As a result, rainbow trout DNA was found in 10 samples (41%).
The Center clarifies that to determine the species composition of fish food products, laboratory staff use both the sequencing method and the polymerase chain reaction (PCR) method.
