With plastic and debris from last year’s tsunami in Japan already causing trouble on American shores, there’s a new cause of domestic concern from that devastating event.

As reported by Reuters, small amounts of cesium-137 and cesium-134 were found in 15 tuna caught in the vicinity of San Diego last August, four months after the disaster in Japan and far outpacing ocean and air debris.

Researchers conducting the study claim that while the tuna were measured to contain five times the amount of cesium-137 than normal, the radiation is not enough to harm people if eaten, and are “far less” than general Japanese safety levels.
