One woman complained of pain in her throat area.
The unnamed woman is 25 years old from Tokyo.
She visited St Luke’s International hospital in the Japanese capital after experiencing a sore throat and irritation for five days.
After a blood test, and after a quick check, the doctor found black worms moving down tonsils.
The rare case, published in the American Journal of Tropical Medicine and Hygiene, states that the worm’s body is black, 38 mm long, 1 mm wide, and is shedding the outer cuticle of the woman’s tonsils.
After further identification, before feeling severe pain in her throat, the woman previously ate sashimi, a Japanese dish that is usually made from raw fish meat.
As can be seen in the image above, the disgusting worm was reportedly still alive after doctors removed it with tweezers.
After the medical procedure was carried out and the worms were removed, the woman’s condition improved quickly.
“DNA and the fact that the worm is in exuviation reveals that this worm is a fourth-stage azarasi Pseudoterranova larva,” said the medical report as quoted by the Mirror, Friday (August 31).
This is a parasite that can infect people who eat raw fish, including sushi and sashimi.
The study also said that the number of reported cases had increased worldwide due to the increasing popularity of sushi and sashimi.
