State-run Tuoi Tre newspaper has quoted Deputy Prime Minister Truong Hoa Binh as saying fishermen should not fish for seafood in deep water within 20 nautical miles from the coast in the four provinces until the Ministry of Health finds it safe to eat and maritime resources restored.

The $US10.6 billion steel complex, which includes a steel plant, a power plant and a deep sea port in Ha Tinh province owned by Formosa Plastics Group, discharged toxins such as cyanide and phenol that exceeded allowable limits during a test run in April 2016.

It caused massive deaths of fish and other sea life along more than 200 kilometres of coastline that devastated fishing communities and tourism in the four provinces. The plant owner was ordered to pay $US500 million in compensation.

In September, the Ministry of Health said tests on samples of sea life in shallow water such as tunas and mackerels in the four provinces were safe to eat, while 132 out of 1,040 samples tested on sea life in deep water such as shrimps, crabs and squids were found to contain phenol.

Several senior officials have been disciplined for their roles in the disaster including Vo Kim Cu, former Communist Party Chief and governor of Ha Tinh province.

The Standing Committee of the National Assembly has accepted Cu's resignation as a deputy of the assembly.
