Rayong has been hit by an oil spill after an undersea pipeline belonging to Star Petroleum Refining Pcl started leaking off the coast of the province late on January 25.
He warned consumers that if dead fish and fish catchers are found with oil stains on them, they should notify the authorities so they can be inspected for contaminants immediately. He urged people against consuming the contaminated products.
Meanwhile, Anan Nakniyom, deputy governor of Rayong province, said a complaints centre had been opened four days ago, and a number of affected people continued to come in and notify them. He said some 700 people had come with complaints so far, and the number was expected to increase.
