Four out of five Thai workers who ate raw snails earlier in the month became infected with a potentially deadly parasite, the Department of Health (DOH) said on Wednesday.
Centers for Disease Control Deputy Director Chou Jih-haw (周志浩) said that three of the workers were in stable condition, while one had left Taiwan and the other had not shown any symptoms of illness.
Three of the workers were reported to have been infected with the parasitic nematode Angiostrongylus cantonensis — an elongated cylindrical worm — early this month and developed symptoms of eosinophilic meningitis, including headaches, fever and vomiting, Chou said.
The DOH discovered that the trio and some of their friends had caught apple snails, Pomacea canaliculata, in fish ponds in southern Taiwan and eaten them raw with sauce.
Snails are usually the primary host of the worm, also known as the rat lungworm — a parasite endemic to Southeast Asia and the Pacific region.
Humans become infected by ingesting the parasite’s larvae, which is then carried in the blood to the central nervous system. This can result in eosinophilic meningitis, which is characterized in the early stages by severe and acute headaches, fever, nausea and vomiting, and stiffness of the neck, and can result in death or permanent brain damage.
Chou said that it was once believed that eating giant African snails could cure certain illnesses and that there were frequent reports in Taiwan of infections of this type of roundworm.
A 70-year-old man in Kaohsiung was treated for the same conditions in 2007 after eating raw frogs in an effort to cure back pain.
Another case in 2005 saw Hualien’s Tzu-Chi Buddhist General Hospital treat a 48-year-old man who had become infected with the parasite after eating raw snails.
In 1998, eight Thai workers came down with eosinophilic meningitis as result of eating raw snails and in 1999, Kaohsiung Veterans General Hospital reported that nine Thai laborers had been infected with rat lungworms.
In light of the recent case, the DOH said it would contact Thai authorities to step up health education to avoid a recurrence of the problem.
AGING: While Japan has 22 submarines, Taiwan only operates four, two of which were commissioned by the US in 1945 and 1946, and transferred to Taiwan in 1973 Taiwan would need at least 12 submarines to reach modern fleet capabilities, CSBC Corp, Taiwan chairman Chen Cheng-hung (陳政宏) said in an interview broadcast on Friday, citing a US assessment. CSBC is testing the nation’s first indigenous defense submarine, the Hai Kun (海鯤, Narwhal), which is scheduled to be delivered to the navy next month or in July. The Hai Kun has completed torpedo-firing tests and is scheduled to undergo overnight sea trials, Chen said on an SET TV military affairs program. Taiwan would require at least 12 submarines to establish a modern submarine force after assessing the nation’s operational environment and defense
A white king snake that frightened passengers and caused a stir on a Taipei MRT train on Friday evening has been claimed by its owner, who would be fined, Taipei Rapid Transit Corp (TRTC) said yesterday. A person on Threads posted that he thought he was lucky to find an empty row of seats on Friday after boarding a train on the Bannan (Blue) Line, only to spot a white snake with black stripes after sitting down. Startled, he jumped up, he wrote, describing the encounter as “terrifying.” “Taipei’s rat control plan: Release snakes on the metro,” one person wrote in reply, referring
The coast guard today said that it had disrupted "illegal" operations by a Chinese research ship in waters close to the nation and driven it away, part of what Taipei sees a provocative pattern of China's stepped up maritime activities. The coast guard said that it on Thursday last week detected the Chinese ship Tongji (同濟號), which was commissioned only last year, 29 nautical miles (54km) southeast of the southern tip of Taiwan, although just outside restricted waters. The ship was observed lowering ropes into the water, suspected to be the deployment of scientific instruments for "illegal" survey operations, and the coast
An inauguration ceremony was held yesterday for the Danjiang Bridge, the world’s longest single-mast asymmetric cable-stayed bridge, ahead of its official opening to traffic on Tuesday, marking a major milestone after nearly three decades of planning and construction. At the ceremony in New Taipei City attended by President William Lai (賴清德), Premier Cho Jung-tai (卓榮泰), Minister of Transportation and Communications Chen Shih-kai (陳世凱) and New Taipei City Mayor Hou Yu-ih (侯友宜), the bridge was hailed as both an engineering landmark and a long-awaited regional transport link connecting Tamsui (淡水) and Bali (八里)
