This is a shocking fact.
As we start the New Year, I am reminded of the importance of growing tea without using pesticides and chemical fertilizers.
The article was published in the President magazine to be released on the 12th of this month.
Figure 1 shows a study on the presence of pesticides in tea leaves and bottled green tea sold in Japan (*1). The tea leaves were purchased at supermarkets and other grocery stores in Japan, while the PET-bottled tea beverages were purchased at convenience stores, where anyone can buy them.
The names of the pesticides are the latest generation of neonicotinoid pesticides (neonicotinoids), of which the seven listed here are approved by Japan.
Unfortunately, 100% of the neonicotinoid pesticides found in Japanese tea were extracted with hot water because they are water soluble. I think we have to accept this as a fact. However, the concentration detected is only a few percent of the residue level, so there is no need to be overly concerned.
This is what Associate Professor Yoshinori Ikenaka of Hokkaido University, one of the team that investigated this shocking fact, said.
The team tested 39 samples of tea leaves and 9 samples of bottled tea, and found neonicotinoids in all of them. The reason for the small amount of neonicotinoids in PET bottles compared to tea leaves is probably due to the small amount of tea leaves used.
In any case, our bodies are being contaminated with pesticides by drinking tea.
Tawara Natural Farm uses natural farming methods to grow tea in an environment as close to nature as possible, without using any pesticides or chemical fertilizers.
Importers and wholesalers are welcome.
Suppliers who are planning to deal in tea are also welcome.
