Sushi chef Mitsuru Tamura uses a radiation detector on seafood before it is prepared in Manhattan's Sushi Yasuda restaurant April 8, 2011 in New York City. The restaurant has begun using the detector as a precautionary measure due to consumer concerns over possible radiation contamination in seafood from the nuclear emergency in Japan. Health officials believe contamination is unlikely to threaten the food supply chain and none has been found in this restaurant. (Photo by Mario Tama/Getty Images)
