Using tea bags and spice pouches may produce good tea and tasty dishes, but people should use them with care to prevent harmful effects, the Consumer Protection Commission said yesterday.
The commission urged the Department of Health to amend regulatory standards for food and utensil packaging to protect public health.
A recent test of 30 items by the commission all met the “Sanitation Standards for Food and Utensil Packaging,” but the results were still worrisome because the regulatory standards do not take into account Taiwanese cooking habits, said Wu Cheng-hsueh (吳政學), a section chief at the commission.
Of the 30 items, 22 used plastic packaging and the other eight used paper.
The plastic packagings did not contain lead or cadmium solutes and their potassium permanganate levels of 1.1mg per liter to 7.9mg per liter were well within the legal limit of 10mg per liter, the commission said.
Neither were there traces of plasticizers, including Di(2-ethylhexyl) phthalate (DEHP), di-n-butyl phthalate (DBP), diisodecyl phthalate (DIDP), diisononyl phthalate (DINP), butylbenzyl phthalate (BBP) and di-octyl phthalate (DOP) — in the packaging, it said.
The six chemicals were targeted because of the plasticizer scare that rattled the nation in May.
Current standards for plastic packaging stipulate that the packaging should not emit solutions containing lead or cadmium when cooked for 30 minutes at 95oC, nor plasticizers such as DEHP or DBP when cooked for an hour at 25oC.
The eight paper packaging products did not contain traces of optical brightening agents (OBA) or formaldehyde, the commission added.
Paper packaging regulations state that there should be no traces of OBA when the product is placed in liquid at or more than 95oC for more than 30 minutes.
However, the commission expressed concern over the fact that Taiwanese dishes are usually cooked over a matter of hours, which may result in elevated levels of the chemicals.
“We have already recommended that the Department of Health consider amending sanitation standards to take into account Taiwanese cooking habits,” Wu said.
The commission said it also found that the tags that come with tea bags or spice pouches are usually not labeled as part of the packaging. A casual test of the tags according to the standards of the Sanitation Standards for Food and Utensil Packaging yielded 11.7 parts per million (parts per million) of potassium permanganate, exceeding the legal amount.
Users of tea bags and coffee bags should avoid dropping or placing the tags in the water, the commission said.
The plastic packaging found in 22 of the 30 samples is a departure from the common expectation that spice pouches are wrapped in cloth or paper bags, the commission said, adding that it had recommended the department consider regulating material specification for foodstuff packaging being steeped or cooked at high temperatures.

More than half of the bamboo vipers captured in Tainan in the past few years were found in the city’s Sinhua District (新化), while other districts had smaller catches or none at all. Every year, Tainan captures about 6,000 snakes which have made their way into people’s homes. Of the six major venomous snakes in Taiwan, the cobra, the many-banded krait, the brown-spotted pit viper and the bamboo viper are the most frequently captured. The high concentration of bamboo vipers captured in Sinhua District is puzzling. Tainan Agriculture Bureau Forestry and Nature Conservation Division head Chu Chien-ming (朱健明) earlier this week said that the
The first bluefin tuna of the season, brought to shore in Pingtung County and weighing 190kg, was yesterday auctioned for NT$10,600 (US$333.5) per kilogram, setting a record high for the local market. The auction was held at the fish market in Donggang Fishing Harbor, where the Siaoliouciou Island-registered fishing vessel Fu Yu Ching No. 2 delivered the “Pingtung First Tuna” it had caught for bidding. Bidding was intense, and the tuna was ultimately jointly purchased by a local restaurant and a local company for NT$10,600 per kilogram — NT$300 ,more than last year — for a total of NT$2.014 million. The 67-year-old skipper
BREACH OF CONTRACT: The bus operators would seek compensation and have demanded that the manufacturer replace the chips with ones that meet regulations Two bus operators found to be using buses with China-made chips are to demand that the original manufacturers replace the systems and provide compensation for breach of contract, the Veterans Affairs Council said yesterday. Democratic Progressive Party Legislator Michelle Lin (林楚茵) yesterday said that Da Nan Bus Co and Shin-Shin Bus Co Ltd have fielded a total of 82 buses that are using Chinese chips. The bus models were made by Tron-E, while the systems provider was CYE Electronics, Lin said. Lin alleged that the buses were using chips manufactured by Huawei subsidiary HiSilicon Co, which presents a national security risk if the
