Tea is considered as a 'health beverage' due its antioxidant properties and resultant beneficial effects on human health. Such a beverage should be free from toxic elements such as pesticide residues and heavy metals. A large scale survey of teas produced in the tea factories of south India had been carried out for a period of three years from 2006 to 2008 and 912 tea samples were analysed for the residues of certain pesticides such as dicofol, ethion, quinalphos, hexaconazole, fenpropathrin, fenvalerate and propargite which are used for pest and disease control in tea in this part of the country. The analytical data proved that only less than 0.5 percentage of tea samples had residues of these pesticides. However, residues of pesticides were below their maximum limits in tea, stipulated by the European Union, Codex Alimentarius Commission of FAO/WHO and Prevention of Food Adulteration Act of Govt. of India.
茶被认为是一种“健康饮品”，因为它具有抗氧化特性，对人体健康有有益的影响。这种饮料应该不含农药残留和重金属等有毒元素。在 2006 年至 2008 年的三年期间，对印度南部茶厂生产的茶叶进行了大规模调查，对 912 个茶叶样本进行了分析，以检测某些农药的残留情况，如狄氏剂、乙硫磷、喹硫磷、己唑醇、甲氰菊酯、氰戊菊酯和丙溴磷，这些农药用于该国这一地区的茶叶病虫害防治。分析数据证明，只有不到 0.5%的茶叶样本含有这些农药的残留。然而，茶叶中的农药残留均低于欧盟、粮农组织/世卫组织食品法典委员会和印度政府《防止食品掺假法》规定的最大限量。
