Original title: The abolition of rare earth limit standards to the tea industry has a positive impact
Recently, the National Health and Family Planning Commission published a new national standard for food safety on its official website, removing the requirements for rare earth limits in plant-based foods, including tea, this set of 26 years of tea "rare earth limit order" was finally lifted. So how did the tea rare earth standard come about? Will the removal of rare earth standards affect consumer rights? What impact will it have on the tea industry? Reporters in this in-depth tea production area to investigate.
rare earths, , radon, radon and other 17 elements, are rare in nature, but not uncommon. Inner Mongolia, Jiangxi, Fujian and other regions are rich in rare earths in the soil.
1991, the Ministry of Health for the first time issued the "Limited Rare Earth Hygiene Standards in Plant Foods", which stipulates that the amount of rare earth oxides per kilogram of tea should not exceed 2 milligrams. For the next 26 years, the Rare Earth Limit Order continued until the new standard was abolished.
, a member of the Chinese Academy of Engineering and a researcher at the Tea Research Institute of the Chinese Academy of Agricultural Sciences, said the tea rare earth limit standard has been of concern to the industry since its implementation. Relevant scientific research institutions from the tea rare earth measurement methods, content levels, source channels and other aspects of research, confirmed that the tea rare earth limit standards there is a certain degree of irrationality. One of the most important points is that the amount of rare earths consumed through tea is safe for the human body.
this view has also been confirmed in this revision of the standard. An interpretation by the National Health and Family Planning Commission, issued at the same time as the new standard, explains why the rare earth limit requirement should be abolished: "According to the risk assessment of the exposure of rare earth elements in the diet of Chinese residents, no significant sub-chronic toxicity was found in the 90-day oral feeding test of the representative rare earth elements radon, radon and radon rats, except for high doses of radon affecting the animal's weight gain and intake."
Tea expert Lin Rongxi said that at present, other tea-producing and importing countries besides China, including the United States, Japan, India, Sri Lanka, Kenya, etc., have not set a limit on rare earths, because there is no scientific conclusion about the impact of rare earths on human health abroad.
the standard is abolished, will the rare earth content in tea rise to the point of harm? In this regard, the official website of the State Health and Planning Commission further explained that even potentially high-exposure groups, such as long-term drinking of pressed tea adults, rare earth mining area residents, the average daily intake of rare earth elements from the diet did not exceed the temporary daily allowed intake of 5%, it can be considered that the current dietary exposure of rare earth elements will not pose a potential health hazard.
Quanliang agricultural technician in the village of Wuhu, said that some tea farmers' tea indicators are very good in all aspects, because the rare earth problem led to "prices fall and sell difficult." For tens of millions of tea farmers, no longer detecting rare earths is undoubtedly a "good thing for farmers."
For tea companies, the abolition of rare earth standards will not only save hundreds of thousands of yuan a year in testing costs, but more importantly, no longer worry about being hit by the problem of rare earths.
of rare earth standards will also save a lot of administrative resources. Lin Youshuang, deputy director of the Anxi County Market Supervision Bureau, said that the original Anxi County government for tea rare earth projects more than 1000 times a year, can now save this part of the energy and financial resources, into monitoring pesticide residues, heavy metals and other really risky projects.
years, relevant national ministries and major tea-producing regions have attached importance to the basic work of risk assessment - data collection, monitoring and collation. In particular, Fujian Province, not only tea, but also soil, season, climate, varieties, location, fertilization, etc. are included in the scope of monitoring, the data are more comprehensive and detailed. The data eventually led to the removal of the rare earth standard. (Reporters Kang Wei and Lin Chao)
