Korea, must be interesting!
Yes, properly cooked through food is a must in some countries.
Pork is notorious for having diseases and parasites, something that was discovered thousands of years ago. Hence the Jewish ( and later Islamic) ban of this meat.
Animals that are omnivorous or carnivorous tend to have more, for us dangerous, parasites. Again, the Middle Eastern people discovered this the hard way ages ago.
My dad told me that when he was a youngster ( pre WW2), he used to help on his grandparents estate with the slaugter and with testing the slaughtered animals for TB and other diseases.
I recall he told me the Vet had a kit to test for some diseases, but when he tested each pig carcass he took a slice sample from the neck and it got tested straight away using slides and a strong magnifying glass.
These were animals that were slaughtered for consumtion by the people there, not for resale to butchers.
I still remember when he told me this, it was when we visited the Andree museum in Gränna in Sweden in the very early -70'.
He told me that Andree must have been a total idiot, as the whole trip was doomed to fail, and that Andree and his young two friends knew very well the danger of eating semi cooked bear meat. Plenty of firewood there on the beaches.
