Radioactive cesium exceeding the legal limit has been detected in four tea products that reached the market and were made with tea leaves from Saitama and Chiba prefectures, a recent health ministry inspection showed.
One of the products, using tea leaves from Chiba Prefecture, contained 2,720 becquerels of cesium per kilogram, far above the government-set limit of 500 becquerels, the Health, Labor and Welfare Ministry said Friday.
The three other products, made with tea leaves from Saitama Prefecture, were found to contain between 800 and 1,530 becquerels of cesium. It is the first time cesium exceeding the maximum limit has been detected in Saitama tea leaves.
