mainly due to the recovery of market demand, short shelf life and high logistics cost.

At present, the popularity of salmon in the domestic market is very high, especially the sashimi of chilled salmon is very popular. The main producing areas are Norway, Chile and Australia, all of which are farmed on a large scale and then flown to China for consumption.

The logistics cost is high, and the value of chilled salmon is high. It has not been frozen, and it is original and tastes good, because the transportation of chilled salmon needs air transportation, resulting in high logistics cost. The shelf life is short, and the shelf life is only about 1 days from the time the fish is taken out to the end of consumption, and the cost is increased due to poor control.

Basic information

There are many parasites in wild salmon, among which Anisodes are the most common, which can easily cause abdominal pain and diarrhea. However, marine parasites cannot survive in human body for a long time. In comparison, there may be fewer parasites in farmed salmon. It is worth noting that rainbow trout cultured in fresh water is sometimes used for sashimi, but its risk is far greater than salmon.

This is because parasites in freshwater fish can live in human body, and the most common one is clonorchiasis. Therefore, rainbow trout cultured in fresh water cannot be eaten raw. Anisodes can freeze to death by freezing. Shanghai Food and Drug Administration recommends freezing at minus 2℃ for more than 24 hours or at minus 35℃ for 15 hours according to foreign standards.
