Many people believe that squid does not contain parasites, and some popular blogs even claim that it is safe to eat because it does not contain parasites. However, this is incorrect.
In particular, the cuttlefish, which is called the king of squid and is a high-quality target for fall eging fishing, also has parasites, but not as many as other fish.
Parasites that affect cuttlefish include Nibernia (niberine tapeworm) and Anisakis , which are found in many fish .
Some say that anasakis can be killed with spicy seasonings such as ginger, garlic, and horseradish, but this is completely false. It will not be killed by pickling in salt or vinegar, so it must be removed before consumption or killed by heating or freezing for a long time.
Also, Nibernia is about 5mm long and looks like a grain of rice in color and shape. It is said that almost 100% of squid have Nibernia. In particular, because many parasites live in the intestines of squid, the part of the squid where the intestines are connected, which is enjoyed for its soft texture, must be cleaned especially thoroughly.
However, this niberinia is known to be harmless to humans. But is there really any need to eat parasites? ^^
Niberinia is particularly abundant in the intestines of cuttlefish and may also be present on the skin surface. Its milky white color contrasts with the white color of the cuttlefish, making it easily identifiable with the naked eye.
In conclusion, when eating squid, especially cuttlefish, it is recommended to heat it to a temperature of 60℃ or higher for more than 1 minute or store it at -20℃ or lower before eating. There is a theory that it takes 24 hours for all parasites to die when frozen, but in Japan, where research on cuttlefish is advanced, 48 hours is recommended.
Also, when eating freshly caught cuttlefish as sashimi, be sure to remove the intestines. Some people enjoy eating the part surrounding the intestines because it has a particularly soft texture, but we recommend that you remove the intestines and wash it thoroughly with salt before eating.
