Les Routes du Silence is a 2004 documentary that investigates public health scandals where industrial interests have overshadowed safety concerns. The film examines cases such as contaminated blood, BSE (mad cow disease), foot-and-mouth disease, asbestos, and glycol ethers, highlighting how financial priorities often took precedence over public well-being. In the aftermath of the Erika oil spill, the documentary delves into the potential toxicity of bitumen, emphasizing the necessity for transparency and the public's right to information. By drawing parallels with the asbestos scandal, it holds accountable the industrialists and officials responsible for safeguarding workers exposed to bitumen fumes.
