A major Swedish industrial project was halted after 34 workers fell ill under mysterious circumstances. The steel company SSAB provided an explanation for the illnesses, leading to the reopening of the worksite and the return of construction workers. However, an investigation by *Dagens Nyheter* reveals that SSAB’s own medical advisors deem the company’s explanation “improbable.” Despite the skepticism, SSAB maintains confidence in its conclusions regarding the cause of the illnesses. The incident has raised concerns about workplace safety and transparency surrounding the health of workers at the site. The project’s future now hinges on resolving the disagreement between the company and its medical experts.
