For three consecutive years the Shizuoka Prefectural Government has contracted a certified independent agency to test, in its own laboratory, green tea for radiation harvested from all parts of the region. Each year all of the samples tested safe for human consumption in accordance with USA (USDA), European Union, Australian and Japanese government standards.
No unsafe tea has ever reached any consumer.
With the health and well being of consumers in mind, the Ministry of Health, Labor and Welfare of Japan has set strict safety standards for green tea. The report “Results of Tests for Radioactivity of Tea Produced in Shizuoka Prefecture” is available. The samples tested were for “brewed tea” which is the state it is actually consumed. The test results for all the samples were nearly the same. Radioactive Cesium 134 and 137 were near zero while the safety limit is 100bq/1KG. Shizuoka green tea has once again been certified to be absolutely safe for your consumption and enjoyment.
