17 cases of bile duct cancer found among printing plant workers
The Ministry of Health, Labor and Welfare said Tuesday that at least 17 cases of bile duct cancer have been reported among workers at printing companies in five prefectures. Eight are known to have died of the disease, the ministry said.
Health Minister Yoko Komiyama told a news conference that the ministry’s Labor Standards Bureau had surveyed 561 printing firms in Tokyo, Osaka, Miyagi, Ishikawa and Shizuoka prefectures in June, Sankei Shimbun reported. The survey was conducted after 12 workers at an Osaka printing plant were diagnosed with bile duct cancer, six of whom have since died, the paper reported.
Komiyama said the ministry will investigate to see if printing companies where workers contracted the cancer were adhering to safety standards on the use of chemicals and cleaning agents, as well as ventilation facilities.
