A raft of experts & charities have urged the UK Government to ban bisphenol A (BPA) in baby bottles because of "compelling scientific evidence" linking it to cancer & other chronic conditions. Launching the campaign, Breast Cancer UK said the weight of research raised clear concerns about BPA. The call has been backed by a number of scientists & charities, including the NCT (formerly National Childbirth Trust), the Cancer Prevention & Education Society & CHEM Trust. BPA is a chemical used in food packaging, including in polycarbonate baby bottles & the epoxy lining of food cans. It belongs to a broad class of compounds called endocrine disruptors. There has been growing concern in the US over the continued use of the chemical, with several states already banning the substance & a number of manufacturers & retail chains switching to BPA-free alternatives. Canada is expected to finalise a ban for its use in baby bottles by the end of the year. The US Federal and Drugs Administration is currently reviewing its approval of BPA.
