When you buy fish from China and eat that fish from China you may get ill and possibly die because fish from China has been shown to pose a significant safety risk for peoples health.
Especially as of now in the year 2020 with the Coronavirus happening I would not want any fish or any type of food that came from China.
You would likely get ill.
But some other foods from China without the Coronavirus going on would be safe to eat.
However I try my best to avoid any food products that are from China because I don't want to risk my health.
