Background of infusion
• “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.

Analytical Method for
Maximum Residue Levels (MRL)
Japanese official analysis methods for
agricultural products announced by
Ministry of Health,Labor and Welfare
• Multi analysis

Japanese Positive List system for MRL
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.

Situation of Japan after Disaster
11th 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.
