A recent diarrhea outbreak among 102 tourists on Green Island off Taitung was caused by a norovirus infection at a local seafood restaurant that had served contaminated raw oysters imported from South Korea, Taiwan’s Food and Drug Administration (FDA) reported Thursday.
Taitung health authorities have received seven suspected food poisoning cases between June 26-30 which involved 102 tourists in six tour groups who displayed symptoms of diarrhea, with 76 of whom having been hospitalized.
After an investigation, Taitung County’s Public Health Bureau found that all the 120 people had eaten raw oysters at a seafood restaurant on Green Island and directed that all restaurants around the island to stop serving raw oysters.
In addition, two raw oyster samples have been found with the presence of norovirus, while two travelers who visited local hospitals tested positive for the norovirus, according to a report from the FDA on July 8.
The FDA then traced the sources of the contaminated products and found they were among a total of 16,447.5 kilograms of raw oysters imported by two aquaculture companies in New Taipei and Kaohsiung from South Korea, a FDA official said Thursday.
