On 8/21/2014, Ministry of Oceans and Fisheries of South Korea announced they retuned 20 t of Japanese marine products from January to July in 2014.
The specific reading was not published, but the ministry comments they detected Cs-134/137 from the returned products.
S. Korea banned imports from Fukushima prefecture and 7 adjacent prefectures last September, so this 20 t of returned marine products are not from the main contaminated regions in Japan. They announce it was 20 t of 9,300 t marine products in total.
