Greenpeace finds banned pesticides in major Chinese tea brands
Is drinking tea good for you? Yes and no, depending on many factors.
Drinking three or more cups of tea a day is just as good as drinking plenty of water — and the flavonoids tea contains helps protect drinkers against heart disease and some cancers. The polyphenol antioxidants found in tea leaves have been shown to prevent cell damage. Other health benefits include protection against tooth plaque and the strengthening of bones.
That’s what British nutritionists from the Kings College London said in a 2006 study published in the European Journal of Clinical Nutrition. The work, which was funded by the United Kingdom’s Tea Council, also dispelled the common belief that tea dehydrates. The British researchers said the amount of caffeine contained in even four cups of tea isn’t enough to cause dehydration — and tea actually rehydrates as well as water does.
So tea is good for you. And it should be more so, if it’s bought from China, the main source and world’s biggest tea producer, right?
No, Greenpeace says in a statement on April 11. That’s because there’s pesticides in that tea.
The international environmental organization says it has detected pesticides banned from use in tea in products made by major Chinese brands — including Tenfu’s Teas, Zhang Yiyuan, Wuyutai and China Tea King.
The pesticides it found in Chinese tea were banned because these could affect fertility and cause permanent genetic damage, Greenpeace says.
The group bought 18 products from nine Chinese tea companies in the major cities of Beijing, Chengdu and Haikou, representing north, west and south China, respectively. Seven of those firms are among China’s top 10 tea sellers. The tea products included green tea, oolong tea and jasmine tea.
After sending the teas for testing in an accredited lab, Greenpeace found that 12 of the 18 samples contained at least one pesticide banned from use in tea — including methomyl and endosulfan.
The World Health Organization (WHO) classifies methomyl as highly hazardous because of its high acute toxicity. Endosulfan is another highly toxic pesticide. Because it bioaccumulates, its toxic effects persist in the body for a long time — that’s why it’s been banned worldwide under the Stockholm Convention.
Specifically, this is what the Greenpeace investigators found:
• Even some of the most famous and expensive teas sold under popular brands — like Wuyutai, Tenfu and Eight Horses — contained pesticides that are banned in China or even worldwide.
• 18 samples contained at least three pesticides.
• 14 out of 18 teas tested contain the kind of pesticides that may affect fertility, harm an unborn child or cause heritable genetic damage.
• 11 of the samples — including Tenfu’s Bi Luo Chun tea and jasmine tea produced by Zhang Yiyuan and Wuyutai — contain both methomyl and endosulfan.
• Richun’s Tieguanyin 803 tea – even showed up with 17 different kinds of pesticides
“You don’t know how many people — and for how long — have unknowingly been drinking toxic pesticides in their tea,” Wang Jing, a food and agriculture campaigner with Greenpeace, said in a statement sent to the Financial Times.
