As late as July 2013 slightly elevated levels of radioactivity were found in beef on sale at Tokyo markets. A fire occurred in the turbine section of the Onagawa Nuclear Power Plant following the earthquake. The blaze was in a building housing the turbine, which is sited separately from the plant's reactor, and was soon extinguished. The plant was shut down as a precaution. On 13 March the lowest-level state of emergency was declared regarding the Onagawa plant as radioactivity readings temporarily exceeded allowed levels in the area of the
