A product survey carried out by The Independent has found that 90 per cent of all canned foods sold in the UK contain bisphenol-A (BPA), a toxic chemical which has been constantly in the headlines for its harmful effect on human health. Claire Dimmer of Breast Cancer UK said that all manufacturers who use BPA should make sure that the cans containing the compound should be clearly labelled. She went on to say that unless this is done, it is impossible for consumers to make their own choices as to whether or not they want to use products that contain BPA.
