A shipment of frozen white shrimp imported from China in June has been found to contain enrofloxacin, an antimicrobial that is not approved for use in fish farming, with much of the shipment believed to have been sold to consumers, a Department of Health official said yesterday.

`not serious'
Cheng said that enrofloxacin is sometimes administered to prevent the reproduction of bacteria in humans. He said the antimicrobial had no serious impact on human health, although it could cause gastrointestinal discomfort, allergies or the formation of crystals in the urinary tract.
The Council of Agriculture prohibits the use of the drug in animal and fish farming in order to prevent the evolution of drug resistant bacteria, he said.

In 2005, the US Food and Drug Administration reported that enrofloxacin had been found to promote the development of drug-resistant strains of Campylobacter, a human pathogen.
The Department of Health banned imports of frozen shrimp from China on Aug. 22 after detecting a carcinogenic drug in seven shrimp shipments, Cheng said, adding that shrimp imported from China before that date may still be on the market.
Cheng said his department had authorized the National Animal Industry Foundation to inspect shrimp samples acquired in Pingtung County on Sept. 3 under a program to monitor aquatic product quality.
Taiwanese scientists have engineered plants that can capture about 50 percent more carbon dioxide and produce more than twice as many seeds as unmodified plants, a breakthrough they hope could one day help mitigate global warming and grow more food staples such as rice. If applied to major food crops, the new system could cut carbon emissions and raise yields “without additional equipment or labor costs,” Academia Sinica researcher and lead author the study Lu Kuan-jen (呂冠箴) said. Academia Sinica president James Liao (廖俊智) said that as humans emit 9.6 billion tonnes of carbon dioxide compared with the 220 billion tonnes absorbed
The Taipei Mass Rapid Transit (MRT) Wanda-Zhonghe Line is 81.7 percent complete, with public opening targeted for the end of 2027, New Taipei City Mayor Hou You-yi (侯友宜) said today. Surrounding roads are to be open to the public by the end of next year, Hou said during an inspection of construction progress. The 9.5km line, featuring nine underground stations and one depot, is expected to connect Chiang Kai-shek Memorial Hall Station to Chukuang Station in New Taipei City’s Jhonghe District (中和). All 18 tunnels for the line are complete, while the main structures of the stations and depot are mostly finished, he
Taipei is to implement widespread road closures around Taipei 101 on Friday to make way for large crowds during the Double Ten National Day celebration, the Taipei Department of Transportation said. A four-minute fireworks display is to be launched from the skyscraper, along with a performance by 500 drones flying in formation above the nearby Nanshan A21 site, starting at 10pm. Vehicle restrictions would occur in phases, they said. From 5pm to 9pm, inner lanes of Songshou Road between Taipei City Hall and Taipei 101 are to be closed, with only the outer lanes remaining open. Between 9pm and 9:40pm, the section is
China’s plan to deploy a new hypersonic ballistic missile at a Chinese People’s Liberation Army Rocket Force (PLARF) base near Taiwan likely targets US airbases and ships in the western Pacific, but it would also present new threats to Taiwan, defense experts said. The New York Times — citing a US Department of Defense report from last year on China’s military power — on Monday reported in an article titled “The missiles threatening Taiwan” that China has stockpiled 3,500 missiles, 1.5 times more than four years earlier. Although it is unclear how many of those missiles were targeting Taiwan, the newspaper reported
