More than 75 percent of major convenience stores, coffee shops and fast food chains continued to use polystyrene cup lids for hot drinks after the material was found to be non-resistant to high temperatures, Democratic Progressive Party (DPP) Taipei City councilors said yesterday, urging Taipei City’s Department of Health to instruct local stores to stop using the lids.
Plastic cup lids made of polystyrene can withstand temperatures of up to 90°C.
The Department of Health (DOH) under the Executive Yuan said polystyrene should be used for non-acidic cold drinks or food, while for hot drinks, stores are advised to use containers made of polypropylene, which can withstand temperatures of up to 140°C and is resistant to acidic, alkaline or alcoholic beverages.
Both polystyrene and polypropylene are legal container materials under the Act Governing Food Sanitation (食品衛生管理法), and starting on July 21, business owners will be required to include information on the materials, maximum temperature and manufacture date of the containers on them. However, the act does not mandate the use of polypropylene for all hot drinks.
A random inspection by DPP Taipei City Councilor Wu Su-yao (吳思瑤) and Liang Wen-chieh (梁文傑) found that only four out of 16 convenience stores, coffee chain stores and fast food chains in Taipei used polypropylene cup lids for take-out coffee.
Three major convenience store chains, including FamilyMart, OKmart and Hi-Life, have replaced polystyrene lids with polypropylene lids, and 85°C Bakery Cafe chain also used polypropylene lids for hot drinks.
President Chain Store Corp, which operates the nation’s largest convenience store chain, 7-Eleven, major coffee chains including Starbucks and Mr Brown Coffee, and fast food chains including McDonalds, Mos Burger and KFC continued to use polystyrene cup lids for hot drinks, the inspection found.
“The temperature of a cup of hot coffee can reach 95°C, and using polystyrene lids for high-temperature food can cause users to ingest carcinogens. The stores that still use polystyrene lids are ignoring the health of consumers and before the department takes more actions to ban the use of the harmful material for hot drinks, the city government should do more to protect our residents,” Wu said.
Taipei Food and Drug Division Director Chen Li-chi (陳立奇) said the department has been communicating with 7-Eleven and other local stores on the use of polypropylene lids, and the department will continue to conduct regular inspections on stores citywide to promote the use of polypropylene lids until July.
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

Whether Japan would help defend Taiwan in case of a cross-strait conflict would depend on the US and the extent to which Japan would be allowed to act under the US-Japan Security Treaty, former Japanese minister of defense Satoshi Morimoto said. As China has not given up on the idea of invading Taiwan by force, to what extent Japan could support US military action would hinge on Washington’s intention and its negotiation with Tokyo, Morimoto said in an interview with the Liberty Times (sister paper of the Taipei Times) yesterday. There has to be sufficient mutual recognition of how Japan could provide
UPDATED TEST: The new rules aim to assess drivers’ awareness of risky behaviors and how they respond under certain circumstances, the Highway Bureau said Driver’s license applicants who fail to yield to pedestrians at intersections or to check blind spots, or omit pointing-and-calling procedures would fail the driving test, the Highway Bureau said yesterday. The change is set to be implemented at the end of the month, and is part of the bureau’s reform of the driving portion of the test, which has been criticized for failing to assess whether drivers can operate vehicles safely. Sedan drivers would be tested regarding yielding to pedestrians and turning their heads to check blind spots, while drivers of large vehicles would be tested on their familiarity with pointing-and-calling
