South Korea orders probe into battery maker's alleged worker injections

South Korea's presidential office announced the directive following reports that workers at a car battery production facility received injections intended to flush lead from their bodies without their informed consent or knowledge of the treatment's true purpose. The injections were allegedly presented to employees as routine vitamin shots during workplace health programs.

The investigation will examine the circumstances surrounding the medical interventions, including whether proper protocols were followed and if workers were adequately informed about the nature of treatments administered. Authorities will also assess compliance with occupational health and safety regulations governing workplace medical procedures and employee protection standards.

The case highlights concerns about worker welfare and transparency in South Korea's manufacturing industry. Lead exposure remains a significant occupational health hazard in battery production, though any medical interventions typically require explicit informed consent and documentation. The inquiry is expected to determine whether established guidelines were violated and what accountability measures may be necessary.

President Lee's order reflects growing scrutiny of corporate practices affecting worker safety, with the investigation likely to influence future regulations governing occupational health programs and employer responsibilities in South Korea.
