• “MACCHA” which is powdered green tea is used for Japanese tea ceremony. It is mixed with hot water and taken itself. As green tea was taken after brewing, it was isolated from “MACCHA”.

• As It is popular to take green tea itself these days by mixing in other foods, new methods are not required to set infusion preparation for analysis.

• Therefore analysis methods were set for “MACCHA” and “another tea” when Food Sanitation Low was effective in 1947.

　 Foods in which any agricultural chemical residues (including pesticides, feed additives, and veterinary drugs) are found in excess of the level determined by the Minister of Health, Labour and Welfare (Uniform Limit:0.01ppm) shall not be produced, imported, processed, used, cooked, or stored for sale, or sold, provided, however, that the foregoing provision shall not be applied to the case where the residue limit levels of chemical substances are stipulated in compositional specification for foods (MRLs:following web) separately.

Authorized Tea MRLs

Situation of Japan after Disaster11th March 2011

Hydrogen explosions scattered radio active substances in the air!

Radio active substances from Fukushima NPP

• 11th March : Massive Earth quake & Tsunami attacked North East Japan

• 12th March : Fukushima Daiichi NPP Unit 1 Hydrogen Explosion

• 14th March : Fukushima Daiichi NPP Unit 3 Hydrogen Explosion

• 15th &16th March : Fukushima Daiichi NPP Unit 4 got fire • 4th – 10th April : Put out contaminated water into the ocean• Radio active substances have been emitted into the air

from Unit 1 & 3, and will not stop for the time being.• So, how much radio active substances are falling down on

our tea gardens in Japan?

Major tea producing areas in Japan

Distance between Fukushima Daiichi Nuclear Power Plant to Shizuoka is 350Km

Kyoto is more than 500Km away from the site.

Environmental radiation surveillance (falling substances during regular period)

• Everyday, all prefecture report total amount of radio active substances falling on land to the Ministry of Education, Culture, Sports, Science & Technology.

• These data are available from the internet web sites.
