Why is "1971 Iraq poison grain disaster" trending?

Wikipedia Overview

The 1971 Iraq poison grain disaster was a mass methylmercury poisoning incident where seed grain treated with a methylmercury fungicide, which was never intended for human consumption, was imported into Iraq from Mexico and the United States. Due to factors like foreign-language labeling and distribution too late into the growing cycle, this toxic grain was consumed as food by Iraqi residents in rural areas of the country. Sufferers experienced paresthesia, ataxia and vision loss, symptoms similar to those observed in Minamata disease-affected Japan. Though the official death toll was 459, figures of as much as ten times greater have been suggested. When it occurred in 1971, the poisoning was the largest mercury poisoning event in history, with cases peaking in February 1972 and stopping by the end of March.
