A recent Japanese government test uncovered radioactive Plutonium-239 and 240 in fish caught off the coast of Japan, according to Energy News.
Japan's Ministry of Heath, Labor and Welfare found that species gathered from a depth of 425 to 980 feet near Onahama, Japan -- about 37 miles from Fukushima -- contained traces of the radioactive element. Of the fish collected and tested June 21-23, anchovies contained the most radiation.
Even though some seafood caught in the area has been labeled safe to consume, it's a very limited amount. Only octopus and sea snail are market approved.
Dr. Ken Buesseler, a marine radioactivity expert, told the Huffington Post, "We still don't know the answers to many important questions concerning the impacts of Fukushima on the oceans. For example, we still don't have a good handle on how much radioactivity was released, and we don't fully understand where it has ended up."
One thing remains clear, according to the National Institute of Radiological Science in Germany, which conducted the analysis. Plutonium is present.
