Why is it said that mackerel from the Sea of Japan is less likely to cause food poisoning even when eaten raw?
- Because the water temperature is low and there are fewer parasites.
- Because it’s said that Anisakis is unlikely to transfer to the flesh
- Because the skin is thick, bacteria have difficulty entering.
See the answer
Because it’s said that Anisakis is unlikely to transfer to the flesh
It’s said that the Anisakis parasites found in mackerel from the Sea of Japan are less likely to migrate into the flesh than those in mackerel from the Pacific side, so eating them relatively raw carries a lower risk of food poisoning. Also, because the region has a long-standing culture of eating raw fish, it may be standard practice for chefs to carefully check that Anisakis hasn’t migrated into the flesh.
