It is reported that researchers have found that Koi-Pla, a popular traditional dish in northeast Thailand, contains carcinogenic parasites, which may lead to liver cancer. Koi-Pla is a dish mixed with chopped raw fish and spices, commonly known as raw fish.

people in Isaan, northeastern Thailand, often eat this dish. For a long time, the proportion of people living in Yishan area suffering from liver cancer is extremely high. More than half of the male cancer patients in this area suffer from liver cancer, and the culprit is the freshwater fish used to make Koi-Pla, which have carcinogenic parasites.

Parasites will attack the bile duct in human body, causing cell inflammation, and the more serious cell inflammation may deteriorate into liver cancer. However, most people infected by parasites will not have any symptoms, but some people will develop liver cancer in a few years.

Because the symptoms of liver cancer appear late, patients are generally not diagnosed with cancer until a later stage. Most patients die within six months to one year after being diagnosed with liver cancer, and the number of patients who can survive for five years is equal to zero.

It is reported that local doctors are helping people understand the potential dangers of eating this kind of fish, and it seems to have achieved initial results. The infection rate in some areas used to be as high as 8%, but now it has begun to decline. Young people began to cook this dish before eating it, but some older people were stubborn and unwilling to change their habit of eating raw food.
