 Marine Products Monitoring Results

 Marine products are being monitored in Chiba Prefecture.

 The results of present tests show that the levels of radioactive Iodine and Cesium in marine products are below the Provisional Standards as of:

 

  May  7^th, 2012 

According to tests conducted after April 2012, there were no saltwater fish exceeding the radiation standards of 100 Bq/kg.

Regarding freshwater fish, carp and stone moroko from Lake Teganuma as well as Crucian carp from the Tonegawa River have exceeded the radiation standards; however, a voluntary stop on the shipment of fish from Lake Teganuma is already being conducted. Additionally, fishing is not being conducted along areas of the Tonegawa River running along Chiba Prefecture (upstream of the estuary barrage).

Chiba Prefecture will continue to monitor the radiation levels in marine products and promptly publish these results in order to ensure the safety of marine products from Chiba Prefecture. We ask that consumers and retailers continue purchasing and business as usual.
