Up to 88 percent of cold noodle products tested by the Consumers’ Foundation contained excessive levels of bacteria, secretary-general Wu Jia-cheng (吳家誠) said yesterday.
Sixteen cold noodle samples — four from convenience chain stores and 12 from traditional shops or vendors — were tested in late May, he said.
All 12 samples from traditional stores or vendors had excessive levels of viable bacteria and 11 contained excessive amounts of Escherichia coli (E. coli) bacterium, which is commonly found in soil and in the intestines of humans and animals and causes severe food poisoning.

The total viable bacteria counts in two samples each from convenience stores also exceeded permitted levels, Wu said
Factors contributing to the presence of E. coli include cross-contamination between raw and cooked food, as well as poor food handling and storage, Wu said.
Total viable bacteria counts, considered to be the most reliable marker of contamination, are often employed to assess food safety and sanitation during the manufacturing process. High bacteria counts can be attributed to improper cleaning and sanitizing of water, equipment and food materials, Wu said.
He said the sanitary conditions for cold noodle products have deteriorated since the foundation began its annual safety checks on the product two years ago. The foundation urged the Department of Health to demand immediate improvements by imposing stricter penalties for food sanitation violations.
Products that fail safety tests should be removed from store shelves and storeowners should improve their food hygiene standards, the foundation said.
A spokesman for the Hi-Life chain of convenience stores said his company had demanded that the manufacturer of the problem products suspend its supply, adding that it would also launch a comprehensive inspection.
A 7-Eleven store representative questioned the foundation’s methodology, saying that cold noodles generally undergo several rounds of testing during the manufacturing process before stored in refrigerators at 4ºC. The samples that failed to pass the foundation’s test might have been tested under high-temperature conditions, the representative said.
The foundation insists its tests were conducted in accordance with professional standards.
Taiwanese paleontologists have discovered fossil evidence that pythons up to 4m long inhabited Taiwan during the Pleistocene epoch, reporting their findings in the international scientific journal Historical Biology. National Taiwan University (NTU) Institute of Ecology and Evolutionary Biology associate professor Tsai Cheng-hsiu (蔡政修) led the team that discovered the largest snake fossil ever found in Taiwan. The single trunk vertebra was discovered in Tainan at the Chiting Formation, dated to between 400,000 and 800,000 years ago in the Middle Pleistocene, the paper said. The area also produced Taiwan’s first avian fossil, as well as crocodile, mammoth, saber-toothed cat and rhinoceros fossils, it said. Discoveries
WATCH FOR HITCHHIKERS: The CDC warned those returning home from Japan to be alert for any contagious diseases that might have come back with them People who have returned from Japan following the World Baseball Classic (WBC) games during the weekend are recommended to watch for symptoms of infectious gastroenteritis, flu and measles for two weeks, the Centers for Disease Control (CDC) said. Flu viruses remain the most common respiratory pathogen in Taiwan in the past four weeks and the influenza B virus accounted for 55.7 percent of the tested cases, exceeding the percentage of influenza A (H3N2) infections and becoming the local dominant strain, CDC Epidemic Intelligence Center Deputy Director Lee Chia-lin (李佳琳) said at a news conference on Tuesday. There were 82,187 hospital visits for
Alumni from Japan’s Kyoto Tachibana Senior High School marching band, widely known as the “Orange Devils,” staged a flash mob performance at the Grand Hotel in Taipei yesterday to thank Taiwan for its support after the Great East Japan Earthquake. The show, performed on the earthquake’s 15th anniversary, drew more than 100 spectators, some of whom arrived two hours before the show to secure a good viewing spot. The 26-member group played selections from “High School Musical,” “Beauty and the Beast,” and their signature piece “Sing Sing Sing” and shouted “I love
