More than 5,000 jars of organic wild blueberry jam made in Italy have been intercepted and recalled by the Tokyo Metropolitan Government in Japan after multiple batches of the fruit spread tested positive for unacceptable levels of radioactive cesium-137. According to the Japanese news source Shukan Asahi, the blueberries used in the Fiordifrutta brand jam, which originated in Bulgaria, were affected by radiation not from a recent nuclear event like Fukushima but rather from the infamous Chernobyl nuclear disaster of 1986.
