Doctors have warned the public about the risks of eating raw meat and drinking tap water after parasitic tapeworms were found in a woman’s spine.
The woman, in her 30s, who often ate sashimi and drank tap water, began experiencing severe back pain and partial paralysis in her legs, the Chinese-language Apple Daily reported.
When the woman’s symptoms worsened, she sought treatment at the Kaohsiung Chang Gung Memorial Hospital, where doctors performed a magnetic resonance imaging (MRI) scan.
Lin Tsu-kung (林祖功), head of the hospital’s Department of Neurology, was quoted by the Apple Daily as saying that the MRI scan showed long irregular shapes in the woman’s lumbar spine, spreading across five vertebrae.
“We saw [her spine] was filled with objects of irregular shapes, but it was not until we operated that we discovered the objects were still moving,” he said, adding that they were shocked to discover sparganosis — a parasitic infection caused by the larvae of tapeworms.
The larvae, with the longest being about 20cm, were removed from the woman’s spine and taken to the hospital’s Department of Pathology for examination.
Lin said the woman was in the habit of drinking tap water and often ate raw tilapia, so the larvae likely entered her body orally and made their way into her spine where they damaged her nervous system, causing back pain, partial paralysis in her legs and urinary dysfunction.
Lin Jui-wei (林瑞偉), a physician at the Department of Pathology, was quoted by the Apple Daily as saying that sparganosis is caused by the larvae of a type of parasitic tapeworm that can grow up to 10m in the human body, adding that its larvae can grow up to 30cm.
While the definitive hosts for this type of tapeworm are dogs and cats, its larvae can live in fish, snakes and humans for many years, the Apple Daily said.
Lin Jui-wei said that although the tapeworm larvae were removed, the damage to the woman’s nervous system might be permanent.
Lin Tsu-kung said people can prevent sparganosis by boiling tap or mountain spring water before drinking it and avoid eating raw meat.

FAST TRACK? Chinese spouses must renounce their Chinese citizenship and pledge allegiance to Taiwan to gain citizenship, some demonstrators said Opponents and supporters of a bill that would allow Chinese spouses to obtain Taiwanese citizenship in four years instead of six staged protests near the Legislative Yuan in Taipei yesterday morning.

SILENT MAJORITY: Only 1 percent of Chinese rejected all options but war to annex Taiwan, while one-third viewed war as unacceptable, a university study showed Many Chinese are more concerned with developments inside their country than with seeking unification with Taiwan, al-Jazeera reported on Friday. Although China claims Taiwan as its own territory and has vowed to annex it, by force if necessary, 23-year-old Chinese Shao Hongtian was quoted by al-Jazeera as saying that “hostilities are not the way to bring China and Taiwan together.” “I want unification to happen peacefully,” Shao said. Al-Jazeera said it changed Shao’s name to respect his wish for anonymity. If peaceful unification is not possible, Shao said he would prefer “things to remain as they are,” adding that many of his friends feel
Taiwan has “absolute air superiority” over China in its own airspace, Deputy Minister of National Defense Po Horng-huei (柏鴻輝) told a meeting of the legislature’s Foreign Affairs and National Defense Committee on Monday, amid concern over whether Taipei could defend itself against a military incursion by Beijing. Po made the remarks in response to a question from Democratic Progressive Party Legislator Chiu Chih-wei (邱志偉) on whether Taiwan would have partial or complete air superiority if Chinese People’s Liberation Army (PLA) warplanes were to enter Taiwan’s airspace. Po, a retired pilot, said that the Taiwanese military has “absolute air superiority” over PLA
A shipment of basil pesto imported by Costco Wholesale Taiwan from the US in the middle of last month was intercepted at the border after testing positive for excessive pesticide residue, the Food and Drug Administration (FDA) said yesterday. Samples taken from a shipment of the Kirkland Signature brand of basil pesto imported by Costco contained 0.1 milligrams per kilogram of ethylene oxide, exceeding the non-detectable limit. Ethylene oxide is a carcinogenic substance that can be used as a pesticide. The 674kg shipment of basil pesto would either be destroyed or returned to its country of origin, as is the procedure for all
