(AP) LOS ANGELES - Across the vast Pacific, the mighty bluefin tuna
carried radioactive contamination that leaked from Japan's crippled
nuclear plant to the shores of the United States 6,000 miles away — the
first time a huge migrating fish has been shown to carry radioactivity
such a distance.
"We were frankly kind of startled," said
Nicholas Fisher, one of the researchers reporting the findings online
Monday in the Proceedings of the National Academy of Sciences.
The
levels of radioactive cesium were 10 times higher than the amount
measured in tuna off the California coast in previous years. But even
so, that's still far below safe-to-eat limits set by the U.S. and
Japanese governments.
