ROCKVILLE, Sept 16: A major study links a chemical used in many plastic products including baby bottles to human problems such as heart disease and diabetes, while US regulators on Tuesday said they still believe it is safe.

The chemical bisphenol A, or BPA, is widely used in plastic food and beverage containers and in the coating of food cans.

Until now, environmental and consumer activists who have questioned the safety of BPA have relied on animal studies. But the study by British researchers in the Journal of the American Medical Association found that among 1,455 US adults, those with the highest levels of BPA were more likely to have heart disease, diabetes and liver-enzyme abnormalities than those with the lowest levels.

US Food and Drug Administration officials said they would review the new findings, which were not taken into consideration when the agency issued a draft conclusion in August that BPA is safe at current exposure levels.—Reuters
