HHS Minamata disease: A disorder caused by methyl mercury poisoning that was first described in the inhabitants of Minamata Bay, Japan and resulted from their eating fish contaminated with mercury industrial waste. The disease is characterized by peripheral sensory loss, tremors, dysarthria, ataxia, and both hearing and visual loss. Minamata disease, sometimes referred to as Chisso-Minamata disease, is a neurological syndrome caused by severe mercury poisoning. Minamata disease has had devastating effects on the region, and as of 2001, there were still 3000 people living with the disease; no new cases of Minamata disease have been reported. Minamata disease played an important role in environmental awareness — namely the effects of pollution — and element toxicology. The factory eventually stopped the process in 1968 and in the same year the Japanese government announced its opinion that the disease was due to consumption of methyl mercury in contaminated fish and seafood. At Kumamoto University, research suggested that the disease was a type of heavy metal poisoning transmitted by fish and shellfish. During the early stages of the Minamata Disease crisis in Minamata, patients, who were diagnosed with Minamata Disease, seemed to be typical and sever cases of the Hunter- Russell syndrome, including sensory disturbance, concentric constriction of the visual field, ataxia, speech impairment and impaired hearing*12*13*14.
