Turin, May 8 - Health authorities in the Valesia area near the Piedmont town of Vercelli said on Wednesday that have found extremely high levels of Cesium 137 in wild boars from the area. Of the 90 boars tested, 15 showed levels of 600 Bq/Kg, well above acceptable levels, authorities said. Health officials are also testing milk, mushrooms and forest berries from the area for radioactivity. Authorities found contamination last March, which they said could originate from toxic waste dumps or a local nuclear reactor that was dismantled in 1987. Scientists have also said that radioactivity found in the boars could possibly stems from Ukraine's Chernobyl nuclear meltdown that happened in 1986, which deposited contamination through much of Europe.
