A Chinese woman had an 8ft-long (2.5-meter) tapeworm removed from her stomach after eating undercooked meat in South East Asia some months ago, UK MailOnline reported.
While traveling for a holiday in January, the 30-year-old woman is believed to have ingested the rare beef.
Although the worm has been removed from her body, she claims to feel sick at the thought of it.
"It's disgusting and almost makes me faint," she told Chinese media.
The patient, identified as Mrs. Li, noticed unusual fluids in her stools after feeling unwell. She immediately went to see a doctor in Xiamen, in China's Fujian province,
Doctors diagnosed her with teniasis - an infection cause by a tapeworm, The Mirror reported.
After being treated with Chinese medicines, Li was able to pass on the tapeworm in May. Doctors said she is recovering well.
"A tapeworm is a parasite that can live in a person's bowel. They tend to be flat, segmented and ribbon-like," UK MailOnline reported.
"Humans can catch them by touching contaminated stools and then touching their mouths, by swallowing food or water that contains traces of contaminated feces or by eating undercooked, contaminated port, beef or fish."
Stomach pain, vomiting and diarrhea, weight loss and malnutrition are some symptoms of a tapeworm infection.
However, some patients remain unaware of their infection due to lack of experiencing symptoms, only recognizing the problem when they see segments of the worm in their stools.
"The tapeworms are clever parasites, they encourage you to eat more of what they like - beer, chocolate and carbohydrates," Michael Mosley, medical journalist, said.
"They can influence your behavior by fiddling with your gut hormones."
While beef tapeworms can easily be treated with tablets, infections through other tapeworms can lead to serious complications.
Tapeworm infections are most commonly seen in the developing world, UK MailOnline reported.
