South Korean food safety inspectors will pay a second visit to Japan next week before deciding whether to lift a ban on imported marine products, the Foreign Ministry said Friday.

During its four-day inspection, the team of South Korean researchers and consumer representatives will visit wholesale markets in Hokkaido, Aomori and Iwate prefectures to assess radiation inspection procedures for seafood. The visit begins on Tuesday.

A similar delegation in December visited the Fukushima No. 1 nuclear power plant and other locations, requesting additional data on ocean radiation levels, officials at the farm ministry said.

South Korea expanded its import ban in September 2013 to include all fishery products from Fukushima and seven other prefectures due to consumer worries over the toxic radioactive water leaks at the meltdown-stricken plant.
