A Tepco sampling survey at the tsunami-crippled Fukushima nuclear plant has found fish around the plant that contain extremely high levels of radiation.<br/> <br />Professor Shugo Watabe explains it is possible the fish accidentally ate mud that may have contained radioactive materials while feeding on shrimp.<br/> <br />He says the contamination is likely to be limited but it was important to prevent contaminated fish from being sold or consumed.<br/> <br />This is not the first time that fish from around Fukushima have been found with radiation but these are reportedly the highest levels found so far.<br/> <br />Many fish from Fukushima are still prohibited from being sold to consumers.
