Hong Kong authorities have banned all aquatic products, sea salt and seaweeds originating from 10 metropolises and prefectures of Japan following the Japanese government’s plan to discharge nuclear-contaminated water at the Fukushima Nuclear Power Station.

The 10 areas are: Tokyo, Fukushima, Ibaraki, Miyagi, Chiba, Gunma, Tochigi, Niigata, Nagano and Saitama, the government said in a notification on Tuesday.

In the food safety order, the Director of Food and Environmental Hygiene prohibited the products from being imported into and supplied in Hong Kong.

The Centre for Food Safety (CFS) of the Food and Environmental Hygiene Department is conducting comprehensive radiological tests on other Japanese aquatic products, sea salt and seaweeds that are not prohibited from import to make sure the radiation levels do not exceed the permitted levels.

According to the center, it tested 185 food samples imported from Japan for radiological levels from Monday noon to Tuesday noon and no sample exceeded the safety limit.

The Agriculture, Fisheries and Conservation Department (AFCD) meanwhile also tested the radiological levels of 50 local catch samples and found them to be admissible.
