Following 34 reported mysterious illnesses among construction workers at SSAB’s new steel plant in Luleå, the county administrative board requested comprehensive investigation into the cause. SSAB has declined to conduct toxicity tests, citing excessive costs, unreasonableness, and lengthy timelines. This refusal was revealed by Dagens Nyheter. The company’s decision raises concerns regarding worker health and safety on the project. Authorities had hoped the tests would identify potential hazardous substances contributing to the illnesses. SSAB has not detailed alternative plans for investigating the cause of the health issues. The new steel plant is a significant investment, but the reported illnesses are prompting scrutiny.
