At least 40 people have been diagnosed as suffering from a
parasite-caused meningitis after eating raw or half-raw snails at
Beijing restaurants.
It is the first time the so-called Guangzhou angiostrongylus
meningitis has been found in Beijing, according to the Beijing
Municipal Health Bureau's website.
It has warned people not to eat raw seafood, which may carry
parasites that threaten health.
The first case, involving a 34-year-old man, was found by the
Beijing Friendship Hospital in June.
The patient suffered from unbearable headaches and nausea after
eating a dish called cold snail meat in the Shuguo Yanyi
Restaurant.
The snail meat was from Amazonian snails Fushouluo in Chinese a
popular dish in Sichuan-style restaurants in Beijing
Doctors took samples from the restaurant and found the parasite
in two of the snails.
By last Thursday, 23 people had been found to suffer from the
meningitis in the capital's hospitals, said the bureau.
They had all eaten cold or spicy snail meat, from Amazonian
snails, at branches of the same restaurant.
According to the bureau, five of the 23 were in a serious
condition, three had left hospital, and two were seemingly
self-cured. No deaths have been reported.
As it can take as long as a month after eating for symptoms to
appear, some diners may not link their headache with the snails,
and doctors may not be able to find the real reason for the
illness.
After local media reported the news, the Beijing Friendship
Hospital received more than 90 people over the weekend, all worried
they might get the disease since they had eaten snail dishes in the
past two months.
The hospital claimed 17 of them were suffering from meningitis.
The youngest patient was 13 years old, the Beijing Evening News
reported yesterday.
Currently the Shuguo Yanyi Restaurant is not selling the dish
while diners elsewhere are refusing to eat Amazonian snails. "After
I heard that Fushouluo could lead to meningitis, I decided not to
order this dish any more," said Wang Yingchao, 34.
According to the bureau, other seafood may also contain
parasites but the Amazonian snail can host more than others.
