Major retailers in Europe...are breaking EU rules designed to protect consumers from harmful chemicals, an investigation has found. Under the landmark Registration Evaluation Authorisation and restriction of Chemicals (REACH)… consumers…have been given the 'right to know' about whether products they are buying contain certain chemicals known to be toxic or carcinogenic…An investigation by the European Environmental Bureau (EEB)…saw just 22 per cent of requests receive adequate responses. Half of the requests were not answered at all by retailers including Tesco, Carrefour and Toys R Us…Many retailers confessed being unable to find the products requested on their inventory or…to get information from suppliers…Carrefour did not respond to enquiries about the EEB investigation but a spokesperson for Tesco said…”We have worked closely with our suppliers to identify these substances and have replaced them with suitable alternatives”.
