Arsenic poisoning in 1955, Morinaga Milk, Japan

Many babies who had taken arsenic-tainted milk produced by Morinaga Milk Industry died. A head of factory production was sentenced to jail after an 18 year long legal case. Families' alliances asked for compensation.


Description

As described in "Industrial Pollution in Japan", UNU, edited by Jun Ui, from June 1955 some infants in western Japan came down with diarrhoea or constipation, vomiting, a swollen abdomen, and a darkening of skin colour. There was no clue as to the cause of this commonly seen problem.

Project Details and Actors
Project DetailsIn 1955, Japanese babies began getting sick. It took a long time — inexcusably long — for the danger to be publicly announced, and as a result, Japan had over ten thousand victims of arsenic poisoning, and over 100 deaths. In the 1970s, the Morinaga company was subject to civil society boycott, and was found guilty in civil and criminal court cases. There were involved negotiations for twenty years on the exact amounts for compensation (of a few thousand USD mortal victim).

Brett Walket (Toxic Archipelago, p. 95) gives these figures for 1981: 13389 ingested the milk, 600 died, 6093 with health difficulties, 624 plagued with retardation.
